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.

TyTN : Frustration of LCD Screen Disalignment Problem

I brought CHT9000 at July 2006 and O2 Trion at August 2006. Both have disalignment problem. At first I thought it is ROM problem and happened for certain model and S/N only.
I try 4 ROMs : I-Mate, Dopod ENG ROM, TyTN and New CHT (Taiwan) ROM.
I installed these ROMs and without installed 3rd parties software. Also I proceed all necessory method to prevent this problem happen such as set a false exchange server for activesync and unclick USB to PC (Check my post).
http://forum.xda-developers.com/viewtopic.php?t=58633
However, all of them have this fuxking disalignment problem. :twisted:
It is hardware problem and I have 2 possible methods to produce this disalignment happen to your TyTN:
1. Body Heat. i.e. Charging, Surf internet and Long talk.
2. Apply very little pressure on LCD. i.e. Cleaning your LCD Panel.
You will find this fxcking disalignment happen again. If you encounter this problem, don't realign the screen manually. Wait few mintues and you will found that it will re-align again. Now you can re-align the screen manually this time.
I already sold my device and not recommend anyone to buy it. It seems that HTC cannot solve this problem and perhaps they don't know the causes.
If you want to buy it, please wait. :wink:
If you brought it, good luck and godspeed.

i have sent mine back because of it

This is the HTC official answer to my request:
Good Afternoon,
There are now procedures in place for fixing the screen alignment issue with the TyTN devices. This is a hardware issue that we have identified and we are offering a replacement to owners of affected devices with two conditions.
1: The device must be returned with all accompanying accessories.
Everything that was in the box when you bought the device must be in the box when you return it.
2: The device must be a Genuine HTC Badged device. This means that the device cannot be a Vodafone v1605, an O2 XDA Trion, a T-Mobile Vario II or any other device based on the TyTN, but that is not actually a TyTN. For these devices, you must contact the Network/Reseller for further advice on this issue.
If you meet these two provisions, you may contact your nearest repair centre to arrange the swap. Please place everything back into the original box and arrange to have the device picked up. It will then be tested to confirm that it has the problem, and then it will be swapped for a replacement unit.
If you are unable to return everything, you will be eligible for a repair under the warranty. For this also, you can contact your nearest repair centre to arrange this.
:roll:
Cheers

Mine goes back Tuesday hopefully the replacement unit will not have the same issue.

There are people who fixed their issue by ROM Upgrade. There are people who just bought their Hermes got this problem. Some has SN HT63XXX. There also some people who been swap their units, and the issue came back.
Well, as I see it, HTC does not know how to fix this issue 100% since it is also happening on some Dopod 838, 8125 (models with sliding keyboard).
I will upgrade my Trion this weekend, and if this issue persists... I will sell this baby and reactivate my trusty Universal.
:lol:

A colleague was able to fix the problem by untightening the two screws on the back of the display and retightening them (not quite as tight as before). His device works without screen alignment problems ever since.
It seems that the screws are too tight which causes tension on the LCD resulting in screen alignment problems.

Magnet Theory
A friend of mine with CHT Dopod 9000, did this and fix his alignment issue.
"When Slide the keyboard, there's a magnet that activates the landscape mode. It's in the back of the screen when you slide it. ( I tried to put it near a magnet and the lanscape activates!)
Then I put a tape at the back of the small protruding (hunchback) just enough to be able to slide it close. This will decrease the magnetism receive from the main body when is close. Then for a week, it's good than before that I need to align 5x a day."
I know this true, since I met him and check his device. I even tried to massage his display, or run it hot.
I will try it myself... let u posted...

The problem only started for me after I installed a screen protector (Martin Fields, an excellent choice!), and since then I've had to re-align the screen every day. This morning I tried the screw trick, so I'll report back if it works for me.
Also I should point out that I have an MDA Vario II, so it looks like those of us who waited are no better off.
The next problem I have to deal with is an unresponsive 'C' key on my keyboard... :wink:

alignment issue is SW or HW or Both...
But unresponsive key(s) is really a HW, my first one has the "L" and backspace.. and it always like that, try to press it fast and it will not register all unlike the rest.
goodluck to all of us!!
:wink:

Anyone that has sent their TyTN back in for repair/replacement for the screen crapalignment, please report back when you get your TyTN back. I want to know if it's worth making the effort to get mine replaced, seeing as I live in Australia and I don't exactly have HTC repair centres, mainly on account of that they don't sell this here. BUT if it's worth getting it repaired/replaced, i'll try to make arrangements with my ebay seller and/or some overseas repairing people.
Cheers guys,
~Louis x_.

Wiki:All problems solved ?! chaos42

Hello to everybody...
Member "Chaos42" has updated Wiki , he said that all problems with Tytn has been solved :
http://wiki.xda-developers.com/index.php?pagename=RecentChanges
He wrote that devices with Serial HT633 has got not problems.
Would you please "Chaos42" tell Us why you think so ? Have you tested a Tytn with this serial ? For how many days ?
As i read here :
www.mobile01.com/topicdetail.php?f=61&t=202144
seems that Tytn(s) with serial beginning with HT634 (that is greater that HT633) are not bug free..Language is Chinese, you can translate it with "Google's tools for languages".
Guys , i'm disoriented...Let's start talking about this news.
Bye!

Hello everybody,
is recieved my replacement unit five days ago. It is an TytN HT633xxx, ROMVers: 1.18.257.2 (07/22/06), Radio: 1.03.03.10, Protocol: 32.34.7010.01H, EXTROMVer: 1.18.257.105
and i have to say this device feels diferent/better then my old HT628 TyTN. The Keyboard feels more solid, the screenaligment problem has not occured once since i am using my device, and the most obvious thing was that the new battery was not fully coverd with a white plastic, but had a metalplate on the bottom instead. Alle buttons work as expected (also on the keyboard), the device is not getting hot when using wlan and the battery seems to last longer. So i am pretty happy with my new TyTn.
If there is anything you want to know or want me to check, feel free to ask

Thank you chaos42 for your reply... :wink: I was a little "suspicious" in my post because i've seen your Wiki's upgrade but i've not seen any your post in this forum before about Tytn and you registered your account only yesterday...So i thougt that this was a new Htc's commercial strategy to sell Tytn that seems to have,at the moment,many bugs.
What can you say us about :
1. During battery charge Tytn getting hot ?
2. This HT633 Tytn is in your hands since ?
3. Wi-fi range is good or poor ?
4. Screen switch from portrait to landscape when Tytn is in his guard or when keyboard is "opened" ?
5. The guard is like the previous or is a new one without magnet ? (The magnet seems to cause alignment and orientation issue to the display)
6. Any freeze problem ?
At the moment you and "randomelements" owns the most recent devices...let us to stay tuned on your tests...Thanks in advance.

Hi,
how did you get the new one? Did you replace it for free thru HTC support?
thanks

I dont work for HTC nor i am in any way related to HTC
For the last ten years i was a heavy and loyal palmuser so, i stayed away from ppc-forums :roll:
the tytn is my first ppc device...
1: This was my problem with my old HT628 especialy when charging and using wlan at the same time. This problem is completly gone. This is maybe related to the new design of the battery, with the metalplate on the bottom. And for me the battery lasts now about 30% longer.
2: five days, playing a lot with it
3: its slightly better, but i only tested it at home, so i have to do some more tests
4: the screen still keeps switching when i take it out of the case, because of the magnets in that damm case. When using the keyboard the screen switches as expected, no more freezeing during screenswitch
5: still the one with magnets
6: no freezing until now, no need for a softreset since i got it
cheers,

Yes, the friendly support told me that during the first 4 weeks they replace it for free. I just called them to ask if its normal that the device gets pretty hot during charging especialy when using wlan at the same time. She said, she has to ask, but after mentioning my screen alignment problems she said i will get a replacement unit, and i should send it in as soon as possible because its a know hardware issue.
I also called the repairecenter in germany, just because i wanted to know how long it will take, and after i said that i got the screen aligment issue, they laughed and told me i will get a replayment unit for sure. four days later i had my new tytn. thumps up for the htc support!

Hello,
Only to say that the initial TyTN Spanish version is:
ROMVers: 1.18.262.2 (07/22/06)
Radio: 1.03.03.10
Protocol: 32.34.7010.01H
EXTROMVer: 1.18.262.105
1. During battery charge Tytn getting hot ? >>> NO
2. This HT633 Tytn is in your hands since ? >>> 2 weeks
3. Wi-fi range is good or poor ? >>> Poor (my Qtek 9100 has better range)
4. Screen switch from portrait to landscape when Tytn is in his guard or when keyboard is "opened" ? >>> YES, like the Qtek 9100, because de magnet (if you put the magnet near the camera buttón screen change, there is a magnetic swith inside)
5. The guard is like the previous or is a new one without magnet ? (The magnet seems to cause alignment and orientation issue to the display) >>> The guard is like the Qtek 9100's, 4 magnets, but leather.
6. Any freeze problem ? >>> NO

I called the servicedesk today and the lady told me different.
They have been waiting for an answer from HTC. And got it yesterday.
HTC mailed them how to repair the Tytn (replace parts) and they are not allowed to replace the Tytn's.
So, new policies??
Well, wil wait and see which phone I get back.

So MacPac you think the magnets in the case are causing the screen alignment issue? Because any magnet powerful enough to effect a switch inside the device cant be having good effects on the screen alignment, is that a logical notion?

Just updated the wiki to include HT634 (HERM300). only issue I've noticed is that some of the keys aren't as responsive as the others. Does anybody else have this version and experiencing similar issues or do I have a duff unit?

screen alignment problem on HT634 Vario II

I'm really pissed off... being an medical intern I really need my Vario II (allready gave away my Vario I) and now I'm experiencing the screen alignment problems as described in previous versions! I was told these problems were solved and now have to re-align my screen about every time I turn on my phone.
Is anybody else experiencing this problem?

anyone who told that this is solved is a joker....
even the HT635XXX is having problem... you can return it back, and wait or go to another unit.
It's an expensive bet on a gamble

Today I received my repaired tytn back. SN HT627.
According to the serviceburo it should now be repaired according to the instruction of HTC.
parts used:
1x Gasket, Keypad.Apache For.
1x MYLAR,LCM CONN, BREEZE FOR
So, hopefully this really solved the problem.
Regards,
Piet

let us know.... if fixed.. it means it's a HW issue.. but dont know why even the latest batch still suffers on this ... :evil:

Screen alignment problem
Those of us with this pesky problem are just dying to hear how "pietg" is getting along after the mylar film Liquid Crystal Monitor connection has been replaced. Not quite sure why they changed the keyboard gasket.
Not that we want to hassle "pietg" but if this is the cure some of us will be straight in there with the tools for another look!!Best give it a few days as the problem sometimes vanishes for lengthy periods anyway - especially I've noticed after you've done a reassembly. (just as you think it's cured it's back)

Will give it a week before judging the repair.
Finally I will be able to start using this thing. A lot to learn, also a lot of usage. So if the problem returns it should be back in one week.
(By the way, the first time to problems occured after I started carring hte phone in my pockets. And the phone came under "pressure".
I wonder when other users are getting back there repaired Tytn, the same parts are replaced.
To be continued ......

hereby an update.
Untill totday still no problems anymore.
So for me the problems are solved.

Good news, partly based on your earlier post on parts replaced, I did my own fix which is also still working well.
Just ocassioally when drawing in "notes" I get spikey lines i.e. when drawing a straight line it actually draws a line with v shaped peaks or sometimes a line like a sinusoidal wave. It always settles down within a minute or so, no need to realign. Once when it happened I noticed the WiFi was reconnecting after a broken connection. This spikey line issue is not a big prblem and I think is unrelated to the usual screen alignment issues. I got the feeling it was caused by power surges or leakage currents when the device was performing power hungry tasks? I saw a LCM manufacturers site that said reistance based LCMs are highly suceptable to both power fluctuations and leakage current interferance.
Anyway your post pretty much confirms the physical cause of most folks general alignment problems.

TyTN LCD Screen Replacement...

I (my 1.5 year old daughter) managed to crack the LCD display on my new TyTN(!!!). I tried transplanting in it an old HTC Wizard display that I had, which turns on as blank white and therefore doesn't help me... I have been looking on ebay and found a company from HK that sells new displays. They have generation 1 or 2 types. see here: http://cgi.ebay.com/Full-LCD-Screen...hZ015QQcategoryZ41343QQtcZphotoQQcmdZViewItem
I assume this is probably the problem I have (??) I guess the display generations are different.
Does anybody have any insight into this? Has anybody replaced an LCD display in their TyTN?
I'll be happy to provide a detailed step-by-step on how to do the replacement if anybody is in the same #$%@y situation I am in...
I'd greatly appreciate any information... I need my phone back...

I deleted your duplicate post in the Upgrading forum btw.

T-mobile Vario II
Hi I have a Tytn from T-mobile (the Vario II). I've been searching here in the uk for a LCD screen also and cannot find one for this anywhere! If you figure it out please let me know, I would be extremely grateful. Taking it to a place called Carphone warhouse tomorrow hopefully they can repair it. Will let you know thanks.

Don't know if it will help you or not, but here it is the part number of HTC TyTN screen, I got it on the description sheet after service center fixed screen alignment issue on mine:
Code: HTC60H00037-01M
Description: TFT-LCD MODULE, TD028STEB1, NEW SUNPLUS, TOPPOLY, TYTN
It was an HTC TyTN with S/N HTC628.
Also try to google this.

OK, so I first tried to place a display from a dead HTC-Wizard in my TyTN - which does not work. It fits perfectly, but all I get is a white screen and somehow it is draining the battery in 1/2 a day. They must have changed something in the display. For now I am only using my phone via voice command to place and receive calls :-(
I ordered a new display from http://stores.ebay.com/hitechhk
They claim as I mentioned to have TyTN displays with generation 1 or 2 although the image says they are displays for O2 mini. I sent a query asking what generation would I need based on photos of my broken display (which looked different than both!). I got a reply that their tech was looking at the pictures to determine which display I need and then got a response that the item shipped - that's communicating across the globe for you... Anyway, my new display is on the way and hopefully it works. I have no idea what they shipped.
I looked at some of the links posted by mikechannon and pof above and these sites seem more B2B (no place to place an order).
Anyway, I'll let you know as soon as it arrives (it shipped 2 days ago) if I'm lucky or not. If so - it's a pretty easy solution. If not...

OK, I am very confused now...
I got my display yesterday from hightechhk - it is not compatible.
Quite frankly, it is identical to my old HTC wizard display and only produces a blank white screen on the TyTN.
Note that this is part number TD028STEB1 and despite the previous mentions that this is TyTN compatible - it is not in my case...
I am back to square one - trying to get an exchange / refund from hightechhk.
Otherwise, my only route will be repair by HTC America (if they take it...).

I just wonder if there is something else wrong and the replacement screen is fine - possibly digitizer. Have you tried a hard reset?

I just decided to start my contingency plan - repair by HTC.
This ordeal started by calling HTC America, who forwarded me to HTC UK.
I need apparently to send my phone to the UK for repair...
Anyway, to your question - I dare not try a hard reset yet until I am officially ready to send my phone for repair to HTC. The reason is that I am using the phone via voice command (the display is dead - so no dialing there...). If I hard reset - I can really only answer incoming calls...
Anyway - I'll give it a try before I ship it, although I doubt it will work.

I have been around many places in the UK...
and can only find two places which will repair it, both costing £150!!! ygeller
do you have the number for HTC in the UK thank you very much hope you get the screen fixed.

I got these numbers: +44 (0) 8458900079 HTC UK
+44 (0) 1202714530
After talking to someone on the first number I was told to call the repair center:
+44 1 908556464 repair center
The repair center hardly answers - you leave a message and they call you back.
I then went to http://support.htceurope.com and created my own repair request. I got a price estimate which was more like 100 GPB including shipping to the US and 5 days typical turnaround. The website generated the RMA process and claimed to have sent me an email with the return instructions - so far, I have not received the email... unbelievable...
Yes. The price sucks. Then again having paid so much for the phone and not being able to use it sucks more...

Yep that ties up with this site:

For reference, I now finally see that the part number I am missing is:
60H00056-00M
the part I got from HK (fits the HTC Wizard) is 60H00037-00M
Hence the mismatch.
Searching the "37" part on google yeilds all sorts of results.
Searching for the "56" part yields nothing... to new? :-(

ygeller Thanks!
Thank you very much ygeller, you have saved me at least £50 and the turnaround is a lot shorter than the 4 weeks I was quoted somewhere else. The internet is a wonderful place most of the time seriously thanks again! Hope all goes well with yours once you get it back.

Problem
Hi!
I have similar problem.
While the charge of battery is over 95% touch screen response me, but later no, rest of device continues working perfectly.
Ygeller, what generation of lcd purchase you?
Ì'm sure that the 1st is not for my device (vodafone v1605 HERM200) but i'm not sure if 2nd will be correct for me.
And if somebody has passed him similar problem and has a solution estaria him very thanked for if me it explained it.
Excuse my bad english.

It was neither gen1 or gen2.
The display they sent me was simply incompatible. It was a Wizard screen - not TyTN.
I couldn't find anywhere on the web a replacement part for TyTN, so I sent it for repair by HTC.

Tytn LCD Module
Just read through thread - trying to pick up on LCD module suppliers.
It seems there is some confusion as to the type of LCD the HTC Tytn and its various "brother" PDA use. Here is what I found out after some extensive correspondence with a supplier in China:
There are a number of incompatible LCD modules each of which is fitted with its own video controller. The marking (usually) with a big sticker on the ribbon like connector states which type is used.
These are the descriptors to look for and order by:
Samsung - LTP280QV-E01
Toppoly - TD025STEB1
Hitachi - TX0704APAA1
The other codes mentioned in the thread are equivalent:
Hitachi - 60H00056-00m
etc...
In any case if anyone knows where to find the Hitachi I would be very happy!

I just got finished replacing the screen on my 8525. I got it from e-bay (gold electronics) had good service and got the exact screen for my phone. around 79 + shipping.

Which screen did you replace?

Info on Tytn LCD Types
Hope this sorts the "White Screen" business out...
These screens differ in the controller they need.
HTC has diversified its use of LCD modules probably to cut prices... but it is a pain to fix!
