LCD ilumination does't work - Wing, P4350 General

Hi,
I've bought P4350 with broken LCD, change it but ilumination doesn't work. It's not problem with connection. I don't know history this phone but it's seems as new. Phone normal work, I can hear sounds etc.
Possibly someone had the same problem. I think it's rather not software problem so maybe someone has repair manual.
Best

Defective Unit? Pls advise

Hi Guys!
My TyTn is acting strangely. In use, the display is first pixelating, getting lines (noise pixels as well), and then fading to completely white. When so it doesn't responde to anything anymore. So a soft reset is needed.....
Also the ringtone when called, is 'out of tune', like a old record player when you push your finger on the record.. LOL
Before I send it back to have it fixed by HTC, do you guys have any idea whats wrong, and maybe even a tip to help me fix this myself?
Tried numerous soft resets, hard reset, and a reinstall of the original WM6 rom (in Dutch).
Did not install any new programs lately, or did change anything on the unit...
Don't want to miss my TyTn... so hate to send it away... as many of you I am hooked badly to my beloved digital companion

It acts like hardware incompatible.
How about flashing with WM6 English version.
I don't think it is software problem.
I agree, not likely to be software. It did not get dropped or take a knock did it?
The two issues of pixelation/white screen may, if you are lucky, just be a connector thats loose. The sound I think is unrelated but again sounds like a poor connection at the white rear speaker connector block - not uncommon.
Both of the above could be caused by a sharp knock. There have also been cases of poor battery connections causing problems.
If you have a warranty use it. If not you can follow the dismantling guides or service manual to dismantle - check connections and re-assemble. Be prepared though, that sending it in might still be required!!

Will send it in
Hi Guys, Thanks fr your replies.
I will take the unit back to the store today.
I am not aware that I bumped it, or neither it has dropped. May be a connection that was allready quite loose to begin with. Lets see what HTC and the store will tell me
Strange thing is, that without my sim in it, and not using it, it stays normal... Have put it aside, and used a very old phone instead, and it is still normal..

Mmmm... that's important information and changes things a bit. Could be a sim card contact or something about the sim. Anyway it tends to suggest that other thoughts about hardware issues may not be correct!
Hope you find the answer at the store.

Xda nova [elf] - display damaged?

hi,
i´ve got a problem with my xda nova. while the device is turned on i see just a white screen with a line of black pixels on my display:
i tried to use the device without the lcd and i think the touchscreen works and also the camera stored pictures on my micro-sd.
after that i did an hard-reset but the display still doesn´t work . now i can just listen to the strange htc sound when it boots and i think it stops there when you have to calibrate the touchscreen - very nice, when you can´t see anything
hope you can help me
sorry for my english, i´m german
If you have any warranty - Take it in to be fixed. Otherwise you are going to have to buy a new screen youself and possibly digitizer as it may also be broken and replace these parts yourself.
This link is a guide you should read on dissasembly of the device, step by step. Good luck

so you think too the lcd is damaged, not the other hardware?
i don´t know if i get warranty, because its not the original rom on it. replacing the display looks pretty easy.

There is no way for me or anyone else to know whether there is any other hardware damaged just by looking at a picture of what looks like a broken LCD. The only way you will know is by changing the LCD to find out. You may find that the Digitizer is broken as well - So you might want to make sure you get one of these as well - I don't think that they are very expensive (from what I have read) You can even look into buying a bricked device off someone for cheap to use as spare parts in case anything else breaks.
Yeah the guide I provided a link for is pretty clear and makes it look pretty easy doesn't it. Thanks to that guide I would not be too afraid to take my device appart to make repairs / replace parts myself if I ever need to.
thank you!
i will order one from china

Dropped my Wizard - White screen

Hi to everyone.
I dropped my wizard and lcd broke so I bought a new one and put it on. The problem is that although it takes phone calls and it syncs to pc, the screen is always white with nothing written..only a white screen. I do not know whether another problem occured besides the broken lcd. I tried to disassemble and reassemble it again but with no success. Any help please?
Hi, If my understanding is correct there are 2 versions of LCD for the Wizard. Are you sure that you have the right one? I'm sorry that I am unable to offer any further advice except to say that if the phone 'phones' and 'syncs' the basics must be working. Also the white screen means that the backlight is working - the problem is the LCD drive. Perhaps worth checking with your replacement supplier that they sent you the correct part?
Good luck!

Strange problem with the screen.

Hi to all,
I have strange problem with my Elf. My screen stopped responding and I thought that the problem is the digitizer. Hard reset didn't help. I ordered a new one and changed it. Unfortunately the situation remained the same. So I got the same working phone from a friend and decided to change some parts to find out where the problem is. The result is..
My front panel(with the new and after that with the old digitizer) connected to the working phone - not responding screen.
My phone connected to the working front panel - not responding screen.
I have no idea what to do. If anyone can help. Exclude the warranty.
There is a small battery on the motherboard. Does anyone know its functions?
I have a suggestion that it is something like cmos battery of the PC.
My idea is to remove it for a while and make new hardware initialization.
I am not sure about that.
I doubt that there is something with the touch screen controller(TSC2046). Is there any way to reset it?

Ensure Replacement unit?

Hello,
i need to send my unit to Service, because it has:
some problems in the keyboard (some keys stop working)
have the problem with the 3.5mm jack (shows handset connected when they arent)
cant get the mic working, it only works in the first call. (i know this is a software problem.)
it has a problem with the display when i place a screen protector (i tryed durasec hightec and martin fields), after a couple of weeks the pda touchscreen it doesnt work
now, because all of this...
i want to ensure SE send me back a new unit, how can i made this without "breaking" the warranty?
thanks!
I'm afraid that the warranty for the thing with the display is already broken. SE didn't suggest the x1-users to use screen protectors...
You cannot force SE to send you a replacement, that's their decision and I would definitely suggest you to do nothing further to destroy your x1 more
no, ok, but i dont know... im not very happy with this high-end phone working so bad...
