[Q] Weird non responsive lcd - HD2 General

I have a EU HD2 with dual boot WP7 and android. The lcd is not respondig at all, all my hard buttons
work flawless, including the power, the light is very poor and when I plug the charge cable the
display flickers just a bit. I can answer and end calls.
This happend after the micro-usb port stoped working. I was uninspired to try and fix it myself,
I managed to fix it, but NOT with a glue gun because is much too difficult. I just put a
little piece of cloth on top of the micro-usb port,so now the micro-usb is pressed against the board and
makes contact and now is charging well. I was extracarefull...but something gone wrong:silly:.
I even sent it to phone service, even if the warranty has expired, they say that I need another display,
but they didn`t have any for replacement. I don` know if I should trust them...
So I ask you guys maybe u can help me.:fingers-crossed:
Sorry for my bad english.
I attached some pics
Thanks

PM me, maybe I can help you...:good:

screen just shows lines

anyone know how/where to get an xda mini II repaired? i'm in italy, but i can careless where it has to go. I'm at the point where i would rather just sell the device for it's workable parts (if there are any)...Today the screen has done a myraid of interesting things...anywhere from blank to thousands of vertical lines....ugh...
ohh yeah...warranty is void....or is time to just move on?
ok...no answers so i thought i would add some images ...anyone seen this before?
Mate i had a similar **** up a while back ...I did a HR and it worked fine..for me it was caused by a Overclocking software [Dnt want to Name it ]
If this dnt work try the Batt out and back in trick
Call ur Local service Center...
mine looks exactly teh same! but it happened after i tried to replace my housing, i screwed up the little gold prongs where the ribbon connector from the lcd plugs in...****! any ideas on how to fix? im the us so service center isnt really an option, and id ont want to send it off.
hi i had the same problem with my magicians, after i changed the housing. i found the problem with my device was that i had not plugged the screen back in properly. all i did was to ensure that it was pushed in properly before i clipped it back in
Menappi -
I had the exact same issue. I reopened the casing WITHOUT disconnecting any cables. I flipped the screen's ribbon black lock up, while maintaining pressure on the ribbon so that it does not pop out. When the black lock lifted, the preasure of my finger moved the ribbon further in . I pushed the black lock down, reassembled the device and ... PRESTO!! the screen works perfectly... and chumps on the bard advised to buy a new screen!!
Good luck
Hi All,
seems, you have problem somewhere in display connector. However, sometimes I see similar picture on physically broken displays, let's imagine, you were careful ad didn't use a hammer during housing replacement.
There are two possibilities: at first - try to remove and re-insert display cable (I hope, you know. how brown lock works). If there is no success - try again. At second - some wire on flat cable may be damaged. Sometimes, good technician with soldering iron can fix it, sometimes not. And if you used force, removing cable, board connector may be damaged too. However, only the experienced man can find it easily.
So, try to carefuly re-insert display cable. Try several times. If you are unsuccessful, you, for sure, need an experienced technician to fix your device.
I hope, you are not enough mad to send device for repair to Russia

Trinity repair question please help

hii !!
my trinity has an lcd problem, it does not turn on , although other functions work fine.
i think it is the lcd socket?? because the black thing that secures the lcd cable fell out and im unable to put it back in. so the lcd cable is inserted in the socket without the black clip. im pretty sure its still in when i reassembled the phone though.
although one of the pins in the socket was previously bent however i managed to make it straight at least i think so. so after many tries, at times the lcd will light up with a dim light, at times the light is brighter, with the touch screen working.
sorry if this is a noob question but i was wondering what needs to be replaced. or if it can be easily fixed???
thanks for reading =) any advice will be greatly appreciated
also the it lights up without any picture. just light thanks
I had the same problem so I sent my phone to HTC repair centre just to find out that they couldn't fix it. I had nothing to lose, so I experimented. Anyway, 4 layers of duct tape will solve your problem. Stick them at the exact place where the black clip was and that's it. Don't give up trying!
thanks for ur suggestion
i tried that but to no avail
the lcd just lights up dimly but no picture, touch screen works
is it possible to be lcd damage, possibly water damage ?
or possibly can it be the mother board ?? all other components work fine, its just the screen
Maybe it's LCD, I don't know.
You have to put it all together and fasten all screws to be sure that my suggestion doesn't work. I must have done it all at least 50 times before I managed to make it work without a problem.

X1 Ribbon cable - what happens and a fix I came up with!

Hi, I come on here quite a lot for information as it's an amazing resource! This time however, I'm attempting to give something back!
I experienced the "black screen on slide out" on Monday. Phone completely screwed. I've also had a few droppages and had it apart once before so there's no way warranty is gonna help!
I stripped it down and soon discovered what it is that actually fails on the ribbon. The coating had worn through due to rubbing on something during the slide out / in process. it had been playing up for a while, probably due to shorting out on the metal case, but now the tracks (aluminium?) had worn right down.....
In pic 1 i've circled the worn area. The shiny section is where i'd tried taping over it to prevent shorting, before i realised the tracks were gone.
Got an almost new one off ebay for 15 quid and, realising it was going to happen again, came up with a solution that, so far, looks like it will work....
A while back I bought some "anti rattle felt" for my car's dashboard - really thin and strong self adhesive felt to prevent squeaking joins between dash sections. I cut a piece of this and stuck it to the new ribbon. Once this stuff is on it's well stuck, by the way!
See pic 2 for the modded ribbon cable.
On reassembly everything is working just fine so far! Here's hoping that it lasts longer than 6 months this time!
Just need a new casing now as mine is decidedly second hand!
Hope this turns out to be of use to someone!
cool story bro
when i took apart my xperia to replace the housing this seemed like a really weak point in the device. glad to see someone who has had the problem has been able to fix it
Why does the screen go black?
Hi,
When the coating wears off the ribbon cable it exposes the tracks in it. when you slide the keyboard out the exposed tracks short out on the metal casing and the screen loses it's input signal.
thats whats happened on mine at least and i presume quite a few others?
HTH!
Update:
That's interesting: My phone was also losing signal with the keyboard out, and occasionally while closed up as well. It would just randomly drop to "no signal" for a few seconds.
It hasn't done it since replacing the ribbon cable.....could be coincidental of course.
I'm having the same problem
It just started a week ago and I got the phone in January off of ebay. I'm new to opening up the phone so could anyone help me find the correct tools or have a link to a site with pictured instructions?
I noticed that the sliding mechanism started to go loose about 4-5 months ago but didn't expect the screen not respond in landscape mode. I have yet to see the other symptoms you all are referring to. I would like to fix this before it get worse.
In mine case it went totaly black after one week of this problem... You have all the instruction on youtube, there is where i looked. For tools you can be inovative, but the exactly right ones come with housings from ebay, it is only 15EUR, and i bet you have some cracks so it wouldn't hurt replacing. That is what i did, along with ordering new sliding mechanizm, and new ribbon cable.
I am open for ideas to prevent my ribbon cable from being cut at it weakest point again.
I'm assuming my flex ribbon went bad yesterday, since sliding the keypad out causes my screen to shut off.
Already ordered a cable off ebay and will attempt to replace it myself :O
Replaced my flex ribbon cable with one I bought on eBay. The screen doesn't turn on at all now, which leads me to believe the cable I was sent is defective. Put the old one back in and it works okay, less landscape mode. ughhh what a pain.
great tips! my input is I bought a case off of ebay that was ~60$ and everything actually fit fine for me...so I wouldn't discount every seller but you do get what you pay for, the 15$ cases are probablly the ones that will give you problems
I working in a mobilephone repair center if anyone need help drop me a priv... i able to get 2nd hand or even brand new components
Replaced the flex ribbon cable -
I got my flex ribbon cable a few weeks ago and took it to my local repair shop. They replaced it but the LCD screen/optical joystick receives no power. The touchscreen and everything else on the phone works just fine now. I thought it was a defective item so it was exchanged with a new one.
Got the repair shop to replace it again and the outcome still remains the same as the first.
Theres no light coming from the screen nor the side illumination.
I just told the repair shop to just place the original back in for the mean time.
Before the repairs, there would be a flicker of white light and random illuminations. Now there's no lights at all except the power botton.
Could it be defective a batch that the seller was sending out? or the repair shop's mistake and is playing dumb so they do not have to admint fault?
Hopefully there's an easy fix to this problem.
-Also I did inspect the ribbon before and after the repair. looks new as the OEm
Can anybody help me out with this new problem after replacing the cable -
perhaps you should try a hard reset. Ive had problems in the past where the optical joystick and the illuminators did not work, and that worked for me.
On the other hand, the top illuminators are on the same piece of hardware as the flex cable that was replaced, so a faulty flex cable is possible. The bottom illuminators are on the circuit board that the optical joystick attaches to, separate but connected to the flex cable.
Ive recently replaced my flex cable and touchscreen. The experience i had with the faulty touch screen was that it appeared to receive no power, but was in fact displaying a dark backlit illumination that could only be seen in the dark. At the same time however, the screen did not display anything. I'm not sure if this is similar to your experience, but if so then your touchscreen would need to be replaced.
ive done all repairs on the xperia myself, and one thing ive discovered is if something doesnt work right after a repair, simply disassembling it and reassembling it to make sure all the connections are properly done has worked for me in the past.
"Before the repairs, there would be a flicker of white light and random illuminations. Now there's no lights at all except the power button."
Now when you say the power button, do you mean that a red light appears under it?
I dont know if i can come to a conclusion or that i can help (or have helped) you come to a conclusion, but i can only assure you that the xperia acts out in strange and weird ways.
Good Luck!

Thanks for the links. I've tried the hardreset and restoring the original rom but the issue is still there. It's really bugging me that everything works but the LCD screen. I'm currently using MyMobiler to use my phone. The touch screen works fine and so does the soft keys. Just no power for the lights. I might just give up and wait for another phone that catches my eye and then tinker with the xperia myself. but if anyone got a solution or want me to test something then I'll give it a try.
My warranty is no longer affective so I'll use my phone as a tester to help others with any problems.
TRIONDAVE, how's your Xperia running now with the cable mod that you did? Its been 6 months since you created the thread. I hope you're still around.
My Xperia X1 works nearly fine, except for the keyboard issues, so I'm thinking of opening it up. If your Ribbon mod helped I might just do it too once I've got it opened. Mine has a MOUNTain of cracks though, and the battery compartment itself is cracked on both side enough to make the compartment CURVED. Hence the Battery cover doesn't sit well.
I'm looking around for broken Xperias which I might be able to use to change the internal cracked casing. Lets see.

My thoughts exactly.
Hello guys, I am in need of real help over here!
Its just that Ive replaced my ribbon cable, the old one got screwd up.
However I got done for 10 minutes ago, tried to start up the phone.. without success :,(
The ribbon cable doesnt have anything to do with the start up, only the screen am I correct? Cause I cannot even start my phone..
Ive connected the charger, but when I remove the battery it shows a red light, meaning no battery, correct?
So what may the problem be exactly? Maybe the battery is all dead, or?
PLEASE HELP!
for the people with ribbon failures how long have you had the phone before it occurred ? im just interested on the cables lifespan.
mine is fine so far but i have noticed the slider is flimsy and rocks left and right.

[q]mayor problems after replacing screen wont boot[19 jan]

Hi i have a htc hd2 with gingerbread, my brother replaced my screen and it work fine the first time with the only problem that you see light in the corners because it didnt fit properly to the frame,
2 he tried to fix it so he used some glue when i turned on it freezed when booting and the color white was showing pink
3 he took it apart again to put it like the first time and it work but now the speaker stoped working so i used it like that for 3 weeks
4 then i told him if he could check the speaker so he took it apart again with no luck and now it freezes again when booting we have tried to find the problem with no luck
do someone have any clue for what is causing the problem please help me
another thing since replacing the screen the first time you turn on the phone has to be with the ac cable because it wont do nothing with the on button after that the button works fine
hope someone can help me and sorry for my poor english
it seems like you might have a loose cable connection somewhere, like the loose flex ribbon or broken sockets. Your only bet is to disassemble your HD2 and assemble it,but this time around, you might want to do it according to proven methods and go step by step. Refer to the links below to help you:
http://www.ifixit.com/Guide/Repair/Installing-HTC-­HD2-PB81120-Screen/5651/2
http://pocketnow.com/hardware-1/official-htc-hd2-disassembly-assembly-training-videos-leaked
if proper disassembly and assembly do not work, then im afraid you have to replace your flex ribbon or get a new screen. it is often hard to troubleshoot what exactly is causing the problem unless you see a visual break in connections. take a really close look at all the connectors that are involved with the screen: the locks, sockets and cables.
do try the above and good luck. hope this helps.

[Q] broken lcd flex cable connector on motherboard!

I need help with broken lcd flex cable connector on motherboard!
I want to now is another connector fits for Trophy
Nothing?
Nobody knows any solution?
I had this happen on my Touch Pro2, but the cable still worked fine after inserting it. Maybe try a bit of electrical tape on top? I don't know if the facing side on the Trophy connector (the side that is broken has any data carry over or not?)
It's some pretty high level damage to do either way.
I try, but not work.
I hate to say it, your out of luck. :/ Unless you can find someone that can do awesome high level soldering and has access to the parts to replace it... that's it. HTC might repair it at a cost, since the phone isn't under warranty anymore, but you'd have to contact them and ask them if they would and what the price would be.
I buy one with broken LCD and Touchscreen and now I have a working Trophy.
Only thing is to change stock ROM with custom ROM.
