screen corrupted / faulty

I got a serious problem with my mda vario here.
sometimes, 7 out of 10 times, when i get a call the screen gets totally corrupted and jumbled like on the picture in the attachment. i can only see black vertical lines on a white screen. in order to make the screen work properly i have to turn the phone off/on (stand-by mode) then.
does anybody know where the problem is?
i have to confess, that the phone slipped out of my hands and fell on the ground 3 times so far.
thanks

well, you say youve dropped it 3 times already? is it possible that something may be loose inside? is there cosmetic damages from dropping?

yes, there are some scratches on it. i don't really think that something is loose or broken, because the screen gets only on icoming calls corrupted.
so i don't think that it is due to a loose contact or something like that...

I have exactly the same problem. I personally think it is unlikely that dropping the phone has caused it as it corrects when you cycle the power button. Any help on this from other forum member would be much appreciated.

Any resoluation this? I have the exact same problem!!

Oh dear ... somethings in the air...
mine's got it also. first time i saw it was a couple of days ago. only happens with the alarm clock in the morning :?
My phone is crap like hell... gotta hard reset and reconfig the damn thing. acting up lately...
(ps... AFAIK i barely dropped the phone... maybe 1 or 2 times. nothing more)

I have the same problem
I have read the service manual of wizard and said:
Unusual Vertical / Horizontal lines or partial display
(1) Check the connection of LCM FPC whether is properly connected. (Is a conector between motherboard and LCD)
(2) Try with another LCM. (LCM=LCD Screen)
(3) Try with another Main Board.
(4) Replace LCM if necessary
(5) Replace Main Board if necessary.
(6) Once the defective part has been identified, verify it again with the defective part whether the
symptom could be duplicated
Any sugestion?

Okay..
so far, i have installed Molski 2.26 rom (30meg free version) and upgrade the radio rom form 2.25 to 2.47.
I have not had another occurance of this so far.
Maybe a fluke.

Screen fixes when pressure applied to bottom of the screen
Guys,
I now have to keep my finger pressed hard against the bottom of the lcd unit to get the screen to display to work properly. it is under warranty with Imate but they want me to send it to Abu Dhabi for repair. I'm in Canada and concerned that I may not get it back.
So has anybody else identified this as being a loose connection rather that a real hard fault. Also has anybody fixed their unit by dismantling and reseating the connections.
Finally has anybody used the Imate repair service and was it timely & reliable?
Any advice would be appreciated.
Mick

This is a real hard fault.. had it with my mini s, took it into the shop, it was away 2 weeks... and in the end they gave me a replacement!!

I agree - took it completely apart and cleaned everything ....
And still have the issue.
Serves me right for buying something in Middlesbrough I suppose
It must be a hard fault with the LCD assembly. Will have to see how Dixons handles an overseas repair.
Take care & thx,
Mick

I had the same problem, in the end i took it into my local t-mob shop to have it repaired, they ended up sending me a new one.

Well, I've exactly the same problem since the past two-three weeks, it also occurs only in the morning. I'm living in the Netherlands and this is happening since it's rather cold over here, especially in the morning (3-4 degree Celcius). Since my bedroom window is open during the night, it gets rather cold in my room.
During the rest of the day it is +8 degree Celcius, and the phone works flawless. Maybe this problem has something to do with the Temperature?

Temperature
Bebob - don't thin so as I have had this problem for a number of months and the temp here in the summer is high (30+ degrees C)
It looks to be a bad connection type issue and may be a bad screen cable. It makes sense though that the issue is at the bottom of the screen cos this is where we press the select buttons all of the time.
Pls keep me posted on how you do. mine is going to a local repair shop (on my dime) tomorrow to see if they can fix it.
If not can any of you guys recomend a new unit that could be considered an upgrade to the KJAM ?
Many thanks
Mick

suggestions needed
friends, i have o2 mini s and got the same problem with screen for the last 3 weeks....
can anyone tell me that will the problem aggravate or else will i be able to use my cell properly for few months...
and also what will be the approx cost of repair..
all suggestions will be warmly appreciated...

It's happened to me as well. I have lived with that for one month now. It is happening, when I touch the cursor keys or when touch the lower part of the display. I tried "shaking/hitting" the xda and it looks better, so I assume it is a faulty connection cable.

I have active Cleartype and no more vertical lines for the past 2 days.
I seems to be a problem when background is white and leters are black.
Regards

similar problem
i dropped the phone (T-Mobile MDA Vario) and now when i turn it on the screen is fine for 5-30 seconds but then it scrambles, but works again if i smack the bottom of the phone on my hand!
t-mobile staff told me there are sensors to identify if it has been dropped. I'm suspicious that it could even be programmed to go "faulty" once it is dropped as the screen is fine for a limited time so it obviously works somewhat. do you know if this is the case? or what's happened? also is it a simple thing i could do myself? i didn't take out insurance so that's why i haven't just claimed off that as i'm really broke
Any help is appreciated
Regards,
Steve

whiteish screen / over temperature
hi,
I have a problem smilar at qtek 9100. I had upgade to my ppc wm5 to wm6 around 3 week ago and overclocked to 221 mhz with batery status today plug-in . 2 days ago Screen became whiteish (almost no contrast or over gamma) and working temperature is around 30c. I tried to re-flash with many kind roms but noting chaged.
Is there anybody has these kind of experice. If I can not solve. I am planing to buy new LCD ( I am not sure new LCD will solve the problem)
Thanks

Same problem here. Dropped it ONE time and the screen went crazy. Sent it to my t-mob shop and they got it repaired. They said in the report that they changed the "flex". Dunno if this helps.

Touchscreen jitter shown on youtube.

Weird! Mine doesn't have this issue, I've tried the Notes line drawing test.

Neither do I..
Go get a replacement, it might be a faulty device. Not sure what's the point here. It is not a problem with the device, it's a problem with YOUR device.

To be fair mine did do it every once in a while, thought it was perhaps sumthing I had on my finger (oil/grease/water/sweat whatnot) however, desensitised the screen and popped a screen protector on it and it's 100% reliable now..

The first video is not mine so it is NOT my device problem and i tested on another hd2 and it made the same thing. That's why i came up with the touchscreen tweak you find on the tips and tweaks sticky but even that do not solve it 100%.
It has been confirmed has software problem like the pink camera here.

that was my exact thought but with a screen protector i could make it do that so i quitted on it at the end.
Good to know i'm not alone here.

Same problem with mine, have applied the touchscreen tweak and aligned the screen which does make it a little better. Maybe the 1.48 rom will fix it and the camera when its officially released.

dude that is exactly what i got. its hard to write one word without the need to correct it. the keyboard is such a horror. it was easier to write on my diamond. im still thinking about to get money back, ask for a replacement or wait for an update.

Unfortunately rom 1.48 does not solve touchscreen problem nor camera pink issue.

So it's a hardware problem ?

Why don't you take your phone back and go get an iPhone instead? Complaining about it here isn't going to help any and it's not, as far as I can tell, a general issue as plenty of people do not see this effect (myself included).

just tried 2 of the tests on mine and i do not get any of the problems.

I just got an HD2 a couple of days ago on O2 in the UK. I have the stock 1.43 ROM at the moment and have this keyboard jitter really bad too . Should I ring O2 and get a replacement, or is a new ROM likely to fix it?
Cheers.

Anyone returned HD2 to HTC with screen issues?

I remember reading a thread about this back when the HD2 was released, but I haven't really thought about it until now.
Since I bought it on the release date, I've been having problems typing on my HD2. The keyboard seems over sensitive and not accurate. When I press one letter, I genereally get the one next to it. When I try and delete the accidental character, I end up typing a heap of L's, M's and P's!
If I do the screen re-alignment it seems to be better for a while, but then after a reboot (which you need to do every couple of days with WinMo!) it goes bad again.
I hate texting now and entering passwords is impossible! I've got to the point where sometimes I want to throw the damn thing away.
I've had 2 iPhones, and HTC Touch Diamond and Touch HD previously so I know its not me. If I try my father-in-laws HD2, I can work it no problem.
I contacted HTC who told me to try a Hard Reset - but as I flash ROMS frequently I know this isn't going to make a difference. They said to contact them if the Hard Reset doesnt work and send the phone in for repair.
Obviously I'll need to reflash a stock ROM first!
Has anyone sent their phone back and what happened? Did it get fixed, and how long does it take?

i have the shaking screen issue when zooming and i cannot detect if it is hardware issue or software or it is normal

Search for "weird touchscreen behaviour".
If you send it back to HTC they'll change the screen and it will come back fixed, or they'll do something random and it won't.

I don't think its just you, I have similar issues! I'm learning to type slower, and there are some links in the tips & hints thread that may help.

I reflashed back to the stock ROM and surprise surprise, same problem.
I emailed HTC back who then said it would have to come back for repair.
They said to phone them to arrange, so its all set up - being collected by UPS tomorrow. Hopefully it will all get sorted.
On another note - I'm now using an old Nokia 3600 Slide while my HD2 is all packed up. I'm loving having an old keypad again! Texting is a delight again, and the small form factor of this phone is great. Its a shame the screen is tiny and the Opera Mini functionality is poop!!
If HTC did a modern version of the Touch Dual with a big touch screen and a slide out keyboard then I'd buy one in a flash! Maybe I'll get a Touch Pro 3 when it comes out

did you try this?? it works for me.Hope it helps

I have been using that - or a similar one - for the last few months, which helps a bit. The problem isn't the sensitivity though, its the accuracy of the screen. When I press 'P' I get 'O', or 'R' I get 'E'. Its like its not quite lined up correctly.

hmm... I had exactly the same problem,but just because screen was too sensitive and this cab helped. Have you also tried align screen??
If this one won`t help I think your fingers are too big (sorry,joke)

Registry tweaks to decrease sensibility help but I think is a hardware problem, so I'd like to know if someone has sent his phone for repair

all my friends iphones have this issue but less than hd2 i think it is capastive screen issue

Sent mine back to O2, not HTC. I was getting light blotches on the screen in various places, they were very prominent when displaying light colours and they were getting gradually worse. Got it back yesterday and it looks brand new.

Did you flash the phone back to stock at all?

Yes, you need to remove the HSPL and that can only be done by flashing a stock rom from the memory stick - USB flashes the stock rom but leaves the HSPL intact. If you don't they will send it back to you saying the warranty is void. As well as replacing my screen they upgraded the stock O2 rom I had on it so they obviously check the software even if it's a hardware issue you have sent it back for. It goes without saying the first thing I did when I opened the box was replace the HSPL and flash Xannytech's Evolution.

I know to get rid of it, was just wondering if you did
Touch wood never had to send mine back but at least they can't tell you've HSPL'd it in the past...

Not all HD2 have this issues, at default (without registry tweaks) was impossible to write anything for me.

You had a different kind of issue, should know if someone with shaking/poor accurancy screen has sent his phone back

Well folks... my phone was picked up last week by UPS and returned to me today.
Before sending it off I reflashed the stock ROM and got rid of HSPL.
I've tested it a bit and am very happy - so I'm now flashing my Miri ROM back on as I type! HTC have replaced 'LCM (LCD)' and replaced 'Rigid-Flex Board (FPC Board)' as their diagnostic stated 'Touch Panel function abnormally and Camera Flash Malfunction'.
Typing feels like it should as the key I hit is now the one that actually presses. I don't know about the camera as I haven't tried it yet - but I didn't think there was anything wrong with it.
My only complaint is that the phone went in for repair with an HTC Screen Protector fitted, and they must've removed and refitted it - as its full of bubbles and knackered! Never mind - I'll order another one.
If anyone has the problems I described... contact HTC and get it sorted, as this is like using a new phone. Hopefully I won't feel the need to throw it again!

I'm mightily pissed off as I have just had to return my Leo back for the 2nd time with exactly the same problem as I had previously (see above). HTC and their crappy cheap LCDs must be costing them a lot of money.

I've been experiencing almost all the bugs in my HD2, last month i sent it back to HTC for repair.
They changed the touchscreen and display because they thought it wasn't bright enough (i didn't notice that).
I got it back a week ago and immediately saw that i now have a different touchscreen, more dots and diagonal lines can be seen.
All the problems are gone and i haven't been experiencing any problems the last week.
My Advise for people with touchscreen problems, have your touchscreen replaced !

i had the white blotches issue too and htc also replaced my screen under warranty (turnaround 11 calendar days) and paid carriage both ways; this despite my lacking a sales invoice, having bought the phone used on ebay and the moisture tab being tripped (which they also replaced).
a very good service from htc only slightly spoiled by the tech who reassembled my phone leaving a fingerprint on the *inside* of the camera lens cover glass which rather than sending it back to them again, i cleaned off myself by means of unscrewing the back panel.

CM 7.0.3 messed up my phone?

I had cyanogen 7.0.3 (stable) with the theme Dark Ginger since it came out until about 6/17/11 .. I was using the phone texting and web a few minutes before the phone restarted by itself I took it out and saw the HTC screen and put it back in my pocket when I checked the phone back a few minutes later after I unlocked the phone by pressing the track pad the screen was black and I know the phone was on since the command buttons on the front of the phone was on .. So took out battery and reboot about 3/4 of the HTC screen was black and the remaining portion had random white lines running vertically when it got to the second splash it was completely black with a few gray lines and when the phone started up the only thing that was on was the lights on the buttons again .. There is no physical damage on the phone so I know the screen was not cracked and even though the whole screen was black I picked up a call by swiping my fingers across it a few times lol ... Just wanted to share my experience maybe you can't have a rom on your phone more than a month or 2? I guess you have to keep flashing new roms on the phone ... I got a new g2 in the end luckily

that does sound more like physical damage or a manufacturing fault. I would be very very surprised if a rom could do that to a phone

You kidding? The vast majority of smartphone owners stay on the stock ROM, and are on the same ROM for many months, maybe even years, aside from OTAs (and depending on your phone and carrier, the OTAs can be very infrequent).
I agree with above, what you've described sounds more like a hardware issue. Even if the phone was not damaged, things just go bad after a while. And screen failure is a known issue with this phone.

Its probably a manufactured fault .. When I had my g1 I used to flash new roms every other day or week I had it for 2 years without any problems .. the g2 is the first time I actually left the same rom on my phone for an extended period hence the thought that the rom was to blame was a possibilty since it looked like it got a virus or something when it crashed* so suddenly :/

It doesn't seem like something a ROM would do to your phone.. probably faulty connections to the screen or something..

I've had a nokia and a motorolla do that, one was dead the other was the connector. If it's under warranty, which I doubt since you've flashed it, send it back otherwise open it up and check the ribbon connector to the lcd screen isn't loose (based on how I fixed my moto). Failing that you could probably get a replacement screen off ebay (based on my nokia).

Thanks for all the responses I actually got an exchange for another g2 .. I appreciate all the hard work the devs put into their roms and the time they spent on them I just posted this topic to maybe solve the problem incase someone else is faced with it .. since I don't have the phone anymore I can't verify if it was the screen or some other mechanical problem

Unresponsive touch screen :(

The top part of my phone does not respond to touch anymore... it is impossible to bring down the notification bar... and once in a while the whole screen goes unresponsive.. tried factory reset but still the same problem..

am having the same problem since 2 days back
after reading some of the posts i found that the Digitizer For HTC G6 Legend A6363 should be replaced with new one i ordered mine from ebay
ebay.com/sch/i.html?_from=R40&_trksid=p5039.m570.l1313&_nkw=Digitizer+For+HTC+G6+Legend+A6363&_sacat=See-All-Categories
waiting for the item to be delivered

I've also got a touchscreen issue: the area of the notification power widgets is unresponsive... the rest of the screen works fine, but I don't know for how long :/

Do you have widgetlocker, by any chance ?
Or a lockscreen replacement which disable the notification bar during the "slide to unlock" state ?

I didn't know there was such thing as widgetlocker. I use CM7 latest nightly, never seen that thing.

I also facing this problem from last 2 weeks and i also think this is digitizer problem. If anyone else found the solution else changing the digitizer, then please post.
This is beautiful phone but htc added a poor quality things in it, due to which many users facing such problems.

Nah.. I dont think its because of widget locker.. its the digitizer..

well that's a shame, gotta buy a new digitizer on ebay after just over 1 year of use...

I know.. this sucks... Im planning to upgrade though.. Any of u guys have any suggestion?

Depends on your carrier if you want suggestions for an upgrade.
...but that would drive the post off-topic.
Sent from my HTC Legend using XDA App

I have the same problem. my screen doesnt work anymore because some water got in from the grill above the screen :S
should I try to take apart and dry off or shall I buy a new digitizer directly?

I think it may be a good idea to try disconnecting your digitizer and reconnect it as it just might be helping. I did it on my girlfriends legend and it has been working perfectly ever since. Maybe a good idea to at least try that before buying a new one. So i guess it could be in the connector to? At least this worked for me.

My touch screen dosent work at times. but after rebooting the phone the problem becomes solved. But the problem comes again after a week or so. Any suggestions guys??

I also have this problem, but if I wait a couple of minutes the touchscreen
becomes responsive again. Half of the screen works when it's unresponsive (right half of the notification bar and down). It's quite annoying but I cannot afford a new phone at the moment.
I'm also wondering if this might be temperature related, this problem reoccurred very often during the summer but stopped during the winter. But now (spring) it's back again.

My problem got worse and the phone became totally unresponsive, changed it, got a new phone.

exact same problem here, mine works when it feels like working, totally random, I simply can't understand why, I doubt it's the temperature... I think its in the device theres something wrong, I smack it numerous time and it works right after a big smack on the screen, or rub your whole hands on the screen, also, the angle you are holding the phone affects this problem, if none of these work, a phone restart always makes it work at the beginning. Oh boy did my phone took and taking much beating... oh well, I wish I could permanatly fixed the problem here, as I was thinking of handing the phone to my brother when I upgrade, I'm using CM 6.1.

I still recommend the same thing that i posted earlier here, her screen still works perfect.

I had the same problem few months ago. The problem is with the touch digitizer. I bought a digitizer on ebay and replaced it myself. After that my phone has been working fine. Its not that hard to replace it if you have a small knowledge about hardware.

I use to get that unresponsive screen issue only in the summertime, plus it gets worse if I add humidity (read: sweat). I just need to give it some time then to dry off/ cool down outside my pocket, and it's all fine again.
