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.

Screen Problem after Charging.

Hey Guys, Can anyone help ?
I plugged my phone in to charge overnight like normal and when i unplugged it next morning the screen will not respond to taps. There are no cracks or damage to the screen and it hasnt had a bump.
A hard reset gets me as far as the calibration screen but again, cant do it.
Does anyone either have any ideas or can anyone recommend a good repair place in the uk ??
thanks.
Andy

Hi Andy,
If you are familiar with rom flashing you could try it before sending to repair in case it's software related.
Good luck

Arrrrrrggghhh-bloody backlight/touch bricked!
I have the same issue and it's driving me nuts!!
pressing the screen bottom left quite hard puts the backlight back on but it goes off as soon as I take my finger off.
Having done a web search, it appears that this may be a firmware issue, but if so, why, after 9 months of trouble free use, has it only just happened?
I'd be very interested if anyone else has solved this issue. Is there patch or is it a hardware issue?
My otherwise excellent touch is effectively bricked-any help or suggestions at all would be appreciated!

A fix (sort of)
I bit the bullet and ordered a replacement LCD module online and fitted it. It worked, proving that there was indeed an issue with the original. Problem is, the quality of the new one is really bad so DON'T buy a replacement online is my advice. I've now sent my beloved Touch back to HTC to get it fixed...
Hopefully I'll have it back and working soon.

FIXED !
i know this is gonna sound weird but i bought a BENQ_E72 while my touch wasnt working and i kinda forgot about the touch in the meantime. Yesterday i came back to the touch and lo and behold its working perfectly. Screen align is working, taps are going through and i cant see a problem.
Now i have read a thread about the Digitizer filling up with dust and yes my front case does have 2 hairline cracks in it so i am thinking a strip apart, new case and clean and go from there if it does it again. Odd how leaving it to discharge compleely for a couple of months has 'cured' the problem
Just thought i would share this with you

[Q] Touch screen problem HW or SW?

Hi,
just recently I bought a used Legend when I was abroad. It seemed to work alright at the shop but I soon discovered that it had a few flaws.
First the symptoms:
The Notification panel rolls down when I touch the screen often rendering the touch screen useless.
Typing on the keyboard in upright position brings down the panel, but if i tilt it it typing the letter "P" will give me "Q"
Some times the screen will start flickering when I hold my finger 10mm above the screen.
The HTC weather app does not show the correct local weather - 3rd party works.
Then to the problem solving attempts:
Reboot - solves the problem for a short while
Resetting to factory defaults - same as above
Disassembled to check for lose components or particles - none found and warranty void I know...
OTA update - I got the 2.1-updat1 2 days ago and the phone worked fine for3-4hrs before it started acting up again. HTC Weather was working.
OTA upgrade - got 2.2 yesterday and had another 3-4hrs without symptoms. HTC Weather app was working.
And a couple of questions:
1) Is it hardware or software?
2) If software - how can it be solved? I`m ok with rooting etc. but would prefer a less time consuming solution. I`m in a Linux environment.
3) If it is hardware - I would probably be able to replace the digitizer (if that`s the problem) but how do i locate it for sure?
4) Would this problem be logged in the phone if so how do i access it?
Software info:
Android version
2.2
Baseband version
47.51.35.17u_7.13.35.05

I could send it in for repair but since the warranty is voided it would probably cost a small fortune and since I find it quite satisfactory to mend things I would really appreciate all the help I could get.
Cheers!

I do not Know how much time you spend with disassembling but it took me about one hour to root it and i was new to this
i think a lot of people can do it in less
i'm on linux too and it is not an problem ( look around for the linux method of creating the goldcard it is realy easy )
i had a similar problem when i tryed to use a screen protector
after removing this and aplying a new clean one it worked ok ( but not great )
after removing this new one it worked great
the legend screen is so scratch resistant that i prefer not to have anything on it
Good luck resolving the problem and please if you manage post how you did it
i'm curious !!

Well, took me about half an hour to disassemble and put the thing back together.
Thanks for the tip about screen protectors - have`nt used any but I thoroughly inspected and cleaned the screen just in case. So that one is ruled out
Any other with ideas of whats most likely, a hardware or a software/firmware error?
I will post if I get it resolved.
BTW: I`m in Oslo, Norway anyone that can recomend a good repair shop?

Hi gesax,
I just started having this very same problem a couple of days ago.
I was about to take my phone appart, but thanks to your post I at least know that it wont change anything (thank you for that)
Quite worried, cause I'm pretty much the only person in Argentina with an HTC Legend, so no chance of sending it to a repair shop
By any chance you found a solution to your problem? or did you have it fixed?
Thanks!
Noah

Have the exact same problem. Haven't found any solution. I'm gonna turn it in.
I have a theory, that usage in cold weather (well below zero) might have caused this...
Anyone who can confirm or dismiss my theory?
Sent from my HTC Legend.

I had the same
New screen for me after bring it to assistance

Yes, it happen to me. It's definitively an hardware problem.

Had this before. Well can't say exactly what the problem is. Might be HW or SW or maybe both. It happened twice to me. Once by software, more like rom actually. After a few days with CM, it stated acting weird. Reflash and everything is good. The other time is because water vapour got between my screen protector and screen. Thus resulting in such effects you're experiencing.

My Legend's in vigorous use in -20 C weather here in Canada. It's not that, trust me.

HD2 (wanted spares/broken phone/advice) Please help !!!!

Hey guys just wondering if there is anybody in Melbourne or Australia or anywhere for that matter that may have a old broken HD2 (preferably T9193) that i might be able to use for spares ?? I currently have one and have dropped it and now it's colours are up the sh*t i have done a screen and digitizer replacement and without any luck the problem still persists any ideas would also be greatly appreciated
Ps. if i twist the phone in oposite directions the problem goes away which leads me to believe that something has come away from the board itself i have looked and cant see a thing any suggestion would be greatly appreciated

Maybe mainboard connector, have you tried applying pressure to connector socket/ribbon with it stripped but screen, mainboard rigged up with battery & bench test it while applying pressure to mainboard connector/ribbon with insulated/earthed tool.
maybe abble to fix it if can find out exact point of problem but most HD2 faults need replacement parts to cure faults long term ...

[Q] A part of touchscreen not responsive.

Alright so, i woke up to find my tablet on the floor, just a 40cm drop.
1 cm of the screen from the bottom seems to have bad response at first.
Do you guys think there is something wrong with the screen itself / internals after the drop or is it just coincidentally a software issue?
I have warranty still available but is there a fix that i can go through with or do i just need to go and get it replaced?

Warranty.
If you manage to patch it up now, it may fail again when out of warranty.

Man something such as dropping doesn't affect the software. The only reson its called software is because you can't harm it by dropping obviously a hardware fault, go for replacement or repairing, before you accidentally or coincidentally run out of it.

Alright! Thanks for your replies guys! I'll go down to the service center tomorrow to get it fixed.
Cheers!
