Hi,
As my wizard dropped in the water it got completely soaked.
I disassembled it to let it dry, see photos attached, put it together again and presto, almost everything works!!!
Just four keys of the keyboard do not work anymore, and as it all happened a week ago now I do not think this will be fixed.
Does anyone know if they do not work because of the water or because of the impact (the Wizard smashed on the street first)?
Has anybody ever fixed a faulty keypad?
Can anybody tell me where I can get a replacement keypad?
Let me know if you need instructions how to disassemble your wizard.
many thanks!

I have no answer to your question, but it is nice to see the inside of the wizard one time.
A couple of other people were asking about disassembly in other posts - so the instructions would probably be handy.
Hi,
I would love some complete instructions on dissasembly as I am about to take mine apart for painting and a hardware mod.
As far as the keyboard goes, you would be surpised how long they retain water, i doubt its a hardware problem, keyboard are pretty much solid state with only a tiny membrane for contacts. However it is this membrane that is most likely to be your problem, the contacts are very close together and covered in a film that can be verry attractive to water as it has rubber over it. So in essence I am saying I bet it is still wet in there, just a few droplets of condensation would do it.
Options, take it a apart and check and leave in a very warm dry place for a day, or II place whole wizard on a warm heater (not hot) for a while and see if that gets it.

Hi,
I also want to know the details of disassembly the wizard.
I think you had better post the instructions o disassembly here as I'm sure there are quite a few people who wuld like to know, me included.
Just a thought by looking at the picture (brave btw!)
Would it be possible to replace the 2,5mm headphone jack by an 3,5mm one and drill out a new hole for the larger connector?
Would be neat if you weren't so dependable on those stupid converters. Not a pretty sight anyway.
Thanks for sharing the photos.
I took mine apart some time ago to fix the stylist problem and when I put it back together some of the keys wouldnt work. The back light wouldnt work either. I found the problem was the little snap that secures the flat cable form the keyboard to the main board. There is a really small clasp that clicks down on the flat cable after you insert it into the connector. Once I took it back apart and snapped it, everything was normal again.
I plan on taking mine apart to change the keyboard form the English/arabic to just English, (anyone know where I can buy the keyboard/keys?) so any instructions you have will be appreciated.
Thanks
The stylii in the picture look like BA stylii.
Do I get 10 points?
will post instructions
OK guys I will put together the instructions and upload them here. I just have absolutely no time now so I hope you can wait a day or two....
Thanks for the comments. I am aware of the little lock that secures the mini flatcable that connects the keypad to the motherboard. I assume that is not the problem as I snapped it securely back in place.
I will try the heater suggestion, I suppose you mean to put the wizard in an oven set at let's say 50 degrees celsius?
The styluses in the photo are from my Qtek 2020. As the Wizard smashed I lost its stylus.... :-(
Sorry the photos do not show the display half of the wizard disassembled... I realised too late that others would benefit from pictures...
Cheers

I dont think I would put it in an oven. I would think that just inside a vehicle sitting in direct sunlight for a few hours would probably do, unless you are in a really cold climate. You may also try some electrical contact cleaner then get some additional heat to it after it evaportates. There is probably something that has trapped some moisture somewhere. Just for info, I dropped my Jamin the other night about 4 feet directly onto a tile floor. It bounced a couple times, ejected the SD card, and reset. But it is working fine. However, I had a bud that dropped his 2 day old Sony Ericsson P900 into water and dried it off immediatly and let it air dry. It worked, but he had problems ever since. It would drop calls and restart all the time. So there may not be a complete fix for it.
Good luck
Hey guys, someone posted the HTC Service manual for the Wizard!
In this manual you see pictures how to disassemble the phone!
It's realy the best manual to use for opening your mobile friend....
Good Luck

I've successfully fixed my girlfriends crappy creative keyboard once after water damage using a pencil. Depending how the keyboard is made, most of the time there will be really thin conductive tracks literally printed on the substrate. The water isn't particularly nice to these tracks and I found that in some parts there was noticale oxidation/corrosion. By very lightly scratching of the affeted paint and then going over it with a graphite pencil this did the trick.
Just an idea, personally I probably wouldn't do it to my vario but then again I'm still in the honeymoon phase with it.
Good luck
I fix phones for a living for many stores and have many phones that have water damage
what you dont do is charge it.. it will burn out the board
what you do is let it dry out, use the service manual and let it dry out in parts
then get white spirit and a toothbrush... dip it in and clean the contacts for yourk eys
once done, again let it try and then see how it goes. thats what i do, although we have a machine that sends out sonic pulses but the above method works too especially when im lazy
HTC Wizard Disassembly
hi guys. a lot of confusion over this simple matter. I don't know where the PDF file everyone's talking about is, most links didnt work, but here's some pics. USE AT YOUR OWN RISK! hahahahaha!

Hi,
I have a O2 xda model
IPL 1.01
SPL 2.21
GSM 01.12.10
OS 1.5.4.2
there is problem in formating the phone.
Even after a hard reset the Os wont boot,
it says that "formating is failed".
there is a prolem in the flash memory of the phone.
please help me with the assembly and disassembly process so that i can fix it.
Any one?
Hi, I hope someone can help me.
I dropped my phone a couple of months ago and now I'm experiencing a problem. It appears to work fine for hours then suddenly starts losing signal strength to the point where it goes altogether. I can start a call with 5 bars and be cut off with no signal in a minute even though I've not moved. It will nearly always lose the signal when I'm on the phone but takes longer when just in other use. All remaining elements of the phone work fine. Please can someone suggest what it could be as it is getting me down...thanks
I'm sure it's a hardware problem.
have got the same problem.Did you already find the problem.In the beginning the signal just dropped but know i even cannot find any service at all.
gr
I've had some luck by raising all the contacts under the sim card but the signal still comes and goes when I use the phone ??
Snap!
I droppped my phone the other day and it is doing exactly the same thing. Mine is a Qtek S110. I used to 'lurk' on this forum ages ago.. but [email protected] BACK to seek help! If and when I get my phone fixed I WILL post and let you know what it is, if I havent already found the solution here!
I think it definately has something to do with the SIM holder, whenever the signal decays and vanishes, if I take out the sim and put it back in it comes back straight away. if I just take out the battery and replace it doesn't
ok.. next time i lose signal I will do that. maybe even run some isopropyl alcohol over the contacts to make sure they are clean.
I will keep you posted in my findings!
(oh.. i tried a makeshift external aerial last night to see if I could see if it was an internal aerial fault. It didnt make any difference, so either my homemade job was [email protected] or it isnt an aerial problem, I'm yet to find out!!)
Cheers!
oh poooop..
that unfortunately didnt work for me.. Oh well. i even tried cleaning the contacts and making sure the 'sprung' contacts were connecting with the Sim correctly.
I actually lost signal until it came back 15 mins later.. hmmmmmmm!!!
Can anyone advise where I can look on the circuit board to see if there is any damage. I am capable of doing this and making a basic repair !!
I had a look at the mda strip down guide on here, but I could see any reference to the aerial or anything. I think I'll have to send off for repair! Doh!
I emailed HPC and they wouldn't take mine back as apparently it was not sold in the UK.
I think I'll give xdarepairs.co.uk a go. a mate of mine said they were good n' quick.
merceeeeeeeeeeeeeeeeeeeeeeeee
no wurries!
the unit that sorunded in red (in the Attached picture) is connected to the main board with tiny connector, and this connector is a male to female connector. the male is solderd to the main board and the female to the unit. my guess is that one of the connector parts (the male or the female) was disconnect from its soldering, and you need to resold it. but it is just my guess based on my experience.
I was taking a look at the mda-jam.pdf guide to removing the case and it suggests that the aerial contact on the board you have pictured is with the front panel.
Can anyone confirm if indeed, the aerial for the phone is the metal casing? That would suggest that the dents in the front of mine could have affected that very contact.
Would still like an answer to my previous post.. but I think I may have fixed my phone temporarily.
Using the above information I got a flat bladed blunt instrument (in this case a normal dinner knife) and carefully placed it into the empty sd card slot. Using the diagram from the case removal guide I applied pressure with the knife to the area where the 'aerial connector' rests against the front bezel, inside, whilst at the same time pushing on the front outer casing with my thumb in the same position.
The thought process being, that it may have worked loose.
Sure enough I have noticed a vast improvement in signal yesterday and today. I am going to keep an eye on the phone today when I go out to see if the signal stays up!
YAY!
Okay.. latest update.
The signal did drop out a little bit throughout the day, So I have taken it upon my self to put my electronic training to good use.
Using the (now much read) case removal manual I carefully .. and I MEAN carefully took my phone to pieces.
I was convinced that the reason my signal kept dropping out was either that something had worked loose or that there were some contacts that needed cleaning or reseating.. as I was able to get a signal by squeezing the case at the top.
So.. Here's what I did (In reverse order)
Page 9 straightened and cleaned the 3 contacts on the RHS plastic plate with isopropyl alcohol. Also cleaned the corresponding contact points on the main PCB with alcohol and dried with a lintless bud.
Page 10 3 contact points, top right and top edge left are the contact points I refer to above. Also cleaned the 2 sprung contacts at the bottom of the PCB RHS page 10
Page 16 cleaned sprung 'Aerial Output' contact with alcohol.. also pushed connector outwards to make a betterr contact. Also cleaned 'contact to the antenna' area and dried thorughly with a lintless bud. Any other contacts I could see were cleaned and dried too.
Whilst putting the phone back together I was very careful not to touch any components. Battery contacts and Sim contacts were also cleaned.
One thing to note in the manula is that it it possible to unclip the connector for the camera prior to removing the plate in page 8. However, it is probably best to follow the guide, if you are unfamiliar with the type of connectors used. They can break easily.
My phone booted correctly and is currently on charge.. I am checking functionality at this very moment and can see that the signal is good and all other parts / hardware functions appear to be good. watch this space! It COULD be one fixed phone!!
I can't remember who on this forum wrote the mda-jam.pdf manual, but I would like to publicly thank you as you have helped fix my phone!
I hope its worked !!! Let me know !
OK!
Well so far I have noticed a dramatic improvement on how the phone was. I am sitting here with full signal, whereas on Saturday I had between 2-3 bars.
I lost a little signal earlier today but as soon as I held the phone up, the siganl came back. So, it's not perfect, but the phone is useable now.
As long as it lasts for the rest of my contract, I'll be happy!!
Dood.
my phone broken so i replaced lcd.
Now when I put sim in, it says SIM CARD IS MISSING or it takes forever and is stuck on searching for signal.
Any ideas?
IDEA!!!!
Broken Sim!
anybody?
Can't be a broken sim. Works fine in two other older phones I have. It's what i've been usning. I miss my MDA.
you can disassembly it again
and see if the sin socked pins are solded??? i dont have more ideas... just because of the falling and broken screen
They are. If I shake the phone, sometimes it works. But then I get the searching for signal endless loop..
Well it seems that its screwed up...
but maybe the socket is fine maybe... the anthena is unsolded or the green label for anthena has a little trash or something... but defineltly is hardware issue because the falling problem.
Okay, i tinkered with the phone this morning for the first time in over a week.
My findings:
The back cover where the camera / antenna when the phone fell I guess the clips broke off. It is no longer seated securely on the top (I can wobble it and remove it very easily)
When this moves the phone loses signal.
Hey guys,
The earpiece speaker on my G1 has developed a fault, the fault being it doesn't appear to work, how easy is it to source a replacement for it and how easy is the repair itself? is there any guides as to how to do it around? (i looked but i couldn't find anything).
I've tried flashing the rom and doing a hard reset but its still faulty.
The loud speakers working fine though so atm all my calls have to be done on the handsfree kit or via loudspeaker which can get annoying.
any help is much appreciated
regards
Streather
Are you using a ROM where sound works?
What ROM are you using?
Tried it with cynagen and the stock tmob one, same results.
Same problem
I'm using CyanogenMod 4.2.5. I dropped the phone about a foot (it fell out of my shirt pocket as I was tying my shoe!), and the earpiece stopped working. Everything else (speaker phone, etc.) works fine.
I've seen a number of similar cases in other forums, so I'm thinking that this is a weak point. I'll attempt disassembly and see if the speaker contacts got moved or something simple. Fortunately, replacement receivers/earpiece/speakers are available over the net.
Meanwhile, I'd love to learn of others' experience with this. The tech manual makes it look like you have to just about completely disassemble the phone to get at the earpiece, even though you can easily access 3 screws on the back of the lcd. Is there a shorter route to the receiver than a complete disassembly?
[update] I found some good info (including a technical manual) by Googling "g1 phone disassembly". And searching for "g1 speaker" on eBay gave some decent looking results.
[update 2] I disassembled my phone, took out the receiver, cleaned its contacts, replaced it, and and reassembled everything. That was a pretty serious chore, and it demonstrated that a nearly complete disassembly is required to access the receiver (yes, including all the stuff at the opposite end of the phone). I don't know how to test the receiver without being in cell range, which my house is not. But at least nearly everything else still works, except the camera--I need to tear back into the phone and make sure I fully seated the FPC. I think finding a replacement receiver will be a challenge--most of what turned up on eBay is actually the main speaker on the back of the phone, and I have yet to find a vendor that sells receivers.
Sadly, you will almost have to tear down the whole unit to get to it. It's not extremly diffucult, but you will need to be steady and gentle. Good luck.
Success!
I haven't seen many report back after tearing apart their phones to address issues with a bad receiver, so here goes. My simple-minded approach of opening it up, cleaning the receiver contacts with a pencil eraser, and ensuring good alignment before reassembling WORKED. I did not have to buy a new receiver.
Now if I can just get my camera to work again (I think I didn't get the cable well seated).
[update]: camera works! Seating that FPC took some nimble fingers--I got it on the 3rd attempt. I hope this proves useful to others who, like me, do not have the warranty option for various reasons.
I dropped my phone once, by accident, same thing happened. The speaker you use to put your ear up to when making a phone call doesn't work, but the speaker phone speaker works as does a bluetooth headset. Called HTC lied said that it just stopped working out of no where, they said its covered under warranty. Luckily the phone is under warranty until March and will be replaced.
I ran into the same problem. I was having intermittent problems with the earpiece. Yesterday I was able to take out the battery and put it in and it started working again. Today that didn't help either. I saw this thread and I thought that I'd try blowing really hard on the earpiece to see if that helps. It seems to be working again! I hope it continues to work.

Can you post details on how to do this?
My camera stopped working too.
I personally found it easier when disassembling the phone to carefully lift the entire camera and IMEI sticker as a whole unit and remove it as part of the motherboard. That way you dont need to mess with that hard to reach connector. So from where you are at, lift the board back out, reattach the camera assembly, and reassemble as a unit. I think you will find it is MUCH easier
Seat the camera FPC fully

I had to lift the motherboard up and away from the hook that held it down in order for the FPC clip to open fully. Then I inserted the FPC *fully* before closing the FPC clip (my failures resulted from not being able to fully seat the FPC because the FPC clip could not fully open as long as the motherboard was in place). Then the trick was to get the motherboard back under its hook without accidentally pulling the FPC back out again. What I did was to press it gently straight down, using my fingernail to ease it past the hook.
Good luck!

Yeah looks like all there is on Ebay for speakers is the back one, the one for the receiver earpiece looks like it has two wire connections at each end while the one for the back speaker has them right next to eachother.
So if anybody had this problem, it is very odd and might have to do with the spring connection maybe.
Still I had this problem before and it fixed itself randomly, but this problem came out of nowhere because 12 hours earlier I had dropped my phone on its back and it continued to work fine. Than on my way driving randomly it would not work and I barely set it down in my car.
Once again hopefully somebody has found a part for this because ebay only has back speaker parts.
Best bet is to blow on it and massage it or tap it until it works, damn this sucks because it is basically the very last step to get to after dissambling your phone. So much work to get to such a common problem for many people.
I almost wanted to try to shortcut it and undo the two screws on the screen section to move it around to make connection. Now I am the deusche bag with the bluetooth in his ear all the time.

That was what I tried at first. It didn't gain me access to the speaker.
Taking the phone apart is a pain. You really need nimble fingers and faith that you're not breaking the phone when you're levering apart the *very* tightly held together plastic parts. HTC did not make this thing with servicing it in mind. Just be sure to have the right tools (including light and a good magnifying glass if you're over 40) and patience.
Removing the 3 screws that are accessible without disassembling the entire phone will get you in there if you are VERY careful. Unfortunately the one I tried this on did not work differently with a known-good speaker in it. You can delicately dig out the old speaker with a knife (Xacto) and drop the new one in. Takes patients, but not nearly as hard as disassembling the entire phone (been there, done that x10)
I have at least one spare speaker. Maybe more, gotta check my stockpile!
Hey,
My phone got dropped in a rum & coke on Saturday, so i soaked it in 90% rubbing alcohol and let it dry in a rice bath. after 4 days in the rice, it looked dry, so i turned it on. IT WORKS! The screen looks a little trippy (the pattern is even changing throughout the day) but the touch and accelerometer work great. The only real problem is the speakers sound like crap. the receiver is so quiet that it sound like they're wispering, and the back speaker is all crackely.
I found a replacement receiver speaker, but as i haven't taken it apart yet, i was hoping one of you could tell me if this looks correct.
http://www.tvc-mall.com/details/Replacement-Speaker-Earpiece-Receiver-for-HTC-G1-HTCO-G1/photos.htm
If so, i guess i'll order both speakers and attempt to replace them.
That looks about right. Bear in mind, of course, that those pictures are greatly magnified. If you haven't taken apart a G1 yet, you're in for a bit of nerve-wracking prying. Just go slowly and be patient. Getting all the way to the receiver speaker means taking the phone most of the way apart.
Thanks!
I have taken apart a phone before, the Dash (excalibur). I had to replace the screen, it involved removing almost every component.
I think i'll go ahead and order it, and cross my fingers. right now the phone isn't much more then a tiny computer, since i can't hear anyone and i don't have a Bluetooth.
Here is the Samsung Galaxy S3 (GT-I9300) Service Manual.
Please take a moment to read the notes and issues about this manual in this post.
For some reason Google didn't pick up that post, so I had to re-post here...
Now, if you are brave and happen to have a GT-I9300, you can still help us by posting some
internal pictures, to verify some issues in the manual. If they are good,
some of them will eventually become part of the SGS3 Hack-Pack.
Thanks and Enjoy!
I will be opening up the phone in the next few days due to me managing to damage the sim card holder section(not holding sim card) So at present i have got somthing putting pressure to keep sim card in place. I have a new sim card holder on order so when it arrives i will pull phone apart and take some pictures.
If you have any advice for me before attempting this please let me know via pm
Do you have any experience in this kind of electronics? I mean, are you planning to replace and solder the SIM card holder by yourself?
If you have not done this type of soldering before, I do not recommend it.
If you do decide to do it on your own, make sure:
You are working on a clean workspace
You are well grounded and not wearing wool clothes mixed with synthetic materials to avoid any ESD.
Have the right tools for the job.(Temp controlled SMD soldering iron + flux and acid-free lead-free SMD solder etc.)
A very steady hand with good eyes!
As for the pictures, keep the environment as bright as possible, preferably daylight. Try to keep your PCB on a bright or neutral background. (Bright cardboard is usually good.) Inspect your pictures and make sure you can read the text on the smallest chips. (The big ones we already know about, its the smaller ones that are difficult to navigate around.) Make sure the pictures are well focused.
Good Luck!
From looking at the pictures I was hoping I don't have to solder the sim card slot in. It looks easily replaceable as it looks like it's just a connector and not soldered
Replaced the sim holder. My camera wasn't good enough to get focus of the smaller chips however it is very very easy to take phone apart. And I guess Samsung are expecting issues with sim slot so they have fixed it using one screw and connected to board using a pull off connecter.
Just in case anyone else is interested the sim holder/sd holder cost me £20, delivered.

Hi guys,
Here is my contribution to da community, hope so it helps.
h t t p s : / / docs . google . com/open?id=0B9lrf7AWQW7ETjRZTkFXb1luN0E
On image 20120616_150200.jpg you can see the region jumpers. The images are of a live demo unit - everything works besides the GSM/3G data. Haven't tested to see if the NFC is working.
The real unit has some more antenna connector. The demo one does not have PBA /printed board antenna/ the ANT102 and ANT103 as well as the capacitors and the coils u may seen them market in red cycles (ANT102, ANT103, C102, C191, L103, L102) there is no room on the MOBO for C192 /or at least I can't find its place/.
Thanks.
^^ Here is the link for above! (Thanks!)
Hi again,
I can confirm that the NFC is working on the live demo unites. According to the original S3 user manual the NFC antennas are build into the battery back.
I still can't figure out what is the "W2" antenna connector for. The Live demo unit has no connector soldered to the motherboard and also lacks the small PCB antenna with the white coaxial cable. Some ppl claim that the W2 is for WiFi antenna, but it is not, because I got great WiFi connectivity tho the lack of such PCB antenna. I can only confirm the WiFi working fine, under "G" type of WiFi networks. The openWRT firmware of my current router has known bug and I can't bring up "N" standard in air, to check if the PCB antenna is for "N" type of WiFi networks.
I also did some testing to see if the PCB is for GLONASS or GPS, and it seams that this PCB antenna with the white coaxial cable is not for any of these services. That's why I think it might be for wifi "N" or 3G data/networks. Donno if the 802.11n requires a separate antenna.
^^ Please post a link to a specific image, that clearly show the connector(s) you're talking about.
Hi I have a live demo unit to, so I think I can help about this =).
I can't show you the mainboard back because I' m new user... xD
I don't really know what you mean with NFC (sorry, I'm not really good with english)
But
W1 is a GSM external antenna conection
W2 is a wifi external antenna conection
And the white wired antenna is for wifi to.
After thinking a lot, if you conect an antenna to the GSM antenna conection (external or the internal lacked in Demo unit) you probably can't use phone function.
That function probably was crippled by software or because demo units don´t have imei maybe o.o.
The only thing I need to try is to connect a microsim to the phone
No one has any insights ???

Samsung galaxy S3 i747
i have a Galaxy S3 SGH-i747m that has been water damaged and given to me so i could try and fix it. I can take pretty much any pictures you want, have openned the phone a couple times now to try and clean it up.
My problem is that the works well, it starts up, unlock the screen, plays sound...but the screen is off. Now at first when i was "playing" with it the screen would flicker on and off to show me the battery charging logo when it was plugged in. I've cleaned the phone and all flex connectors with some products. the phone still turns on and works but my screen is off. It detects the touch since i can unlock the screen ( it plays the water sound when i slide my finger on the screen) and speaker works when i boot it up (little booting sounds).
I was thinking there might be a small fuse on board for the screen backlight and that could be blown. I was also thinking my battery might be damaged and is not giving the phone the right voltage to the right connectors or something so i have ordered a new battery on ebay (under 4$) and am waiting for it.
Anyone has an idea to some specific things i should be looking for ? only thing haven't disassemble is the digitizer from the framebecause doing so would surely break the glass. It bums me up a bit since there are some electronics behind the frame that could have been damaged by the water that i couldn't see.

check if you can see anything on the screen, use some extra light, torch for example.
if so - then its more likely that the LEDs in the display panel are damaged, since it flickered, as you said. also could be the driver circuit for backlight. Clean connectors for display panel, use magnifier, or better microscope to check for corrosion. use IPA to clean or scrape off the corrosion.
also - maybe this is not the right place to discuss this.

i have a Galaxy S3 SGH-i747m that has been water damaged and given to me so i could try and fix it. I can take pretty much any pictures you want, have openned the phone a couple times now to try and clean it up.
My problem is that the works well, it starts up, unlock the screen, plays sound...but the screen is off. Now at first when i was "playing" with it the screen would flicker on and off to show me the battery charging logo when it was plugged in. I've cleaned the phone and all flex connectors with some products. the phone still turns on and works but my screen is off. It detects the touch since i can unlock the screen ( it plays the water sound when i slide my finger on the screen) and speaker works when i boot it up (little booting sounds).
I was thinking there might be a small fuse on board for the screen backlight and that could be blown. I was also thinking my battery might be damaged and is not giving the phone the right voltage to the right connectors or something so i have ordered a new battery on ebay (under 4$) and am waiting for it.
Anyone has an idea to some specific things i should be looking for ? only thing haven't disassemble is the digitizer from the framebecause doing so would surely break the glass. It bums me up a bit since there are some electronics behind the frame that could have been damaged by the water that i couldn't see.

I have identical symptoms with my i9300.
1. Water damaged
2. Dried in a can of rice etc over several days
3. Cleaned under sim card, lots of debris there, looked scorched, I cleaned with alcohol and a brush in an ESD protected environment.
4. Re assembled, the display briefly flashed on, and showed the expected "Battery is low, an d No Sim Card" then powered off.
5. Now after charging the battery and emplacing my sim card, I hear the proper musical tones when the phone boots but the screen doesn't light.
Where you able to get the screen working?
I am going to try a more throughal cleaning and I will try viewing the LCD under a more power full light.
I too worry that just getting the LCD screen replaced might not work; the screen may be fine but the mother board LCD power supply might be at fault...
I will keep you posted and keep an eye on this forum to find out how to fix this.
