White screen all the time. What should I buy? - 8525, TyTN, MDA Vario II, JasJam General

Hello,
for first I've already read some topic covering the white screen problem. I have the white screen every time on my Hermes since booted. Going into bootloader also shows white screen. I don't see any signs of misalignment.
I've already taken apart my Hermes and reconnected all connectors I've seen, including D-Pad connector, tightening and loosening the screws by it. I see there's nothing else I can fix without replacing any parts (or am I wrong?) What should I buy? Do you think that the actual screen may be faulty? Or maybe the flex is damaged and I should buy it? (well I think that some chip is connected to flex so I don't know if it can be replaced anyway). My main question is: if the screen is all white, is it possible that the actual screen be faulty?

It could be a number of things which could amount to $$$$ by throwing parts at the phone - may be cheaper to just buy another. Before the completely all white screen did you have occasional white screens with increasing frequency? First try some of the fixes for correcting whitescreens - pressure on the dpad - etc. If you still get nothing the chip could have come loose - but who knows?!!!! Need some more information - history etc.

Unfortunately don't know the history... bought cheap off ebay hoping it can be easily fixed already ordered the screen, if no luck, will send as spares/repair in my country - should earn something anyway.

i have a fault with mine some times (well a lot now) when i open it or close it all the way i get a funny fuzzing on the screen and some times it just ends up going black, move it back and forth a bit and the screen collour is inverted. i have to press the power button twice once for off then back on and it stays normal collours till u move the screen again. is this called white screen?

Not really - yours should be an easy fix. Seems like the flex cable is either loose or cracked slightly. It only occurs when you slide the keyboard out right? Any problems with the front keypad - with the unit closed?

Is this the forum for repair advice? Digitiser recalibration

I dropped my phone and the screen now doesnt respond properly: The hardware DID successfully upgrade to the XDA ROM. But touching it causes the backlight to go on, - but most of the keys dont do what one would expect them to do: The phone turns on with a reminder from the calendar on the screen which wont DISMISS or CLOSE. Pressing on the windows logo and then on the phone key causes the calendar to come up and I am not sure which numbers are entered when I do manage to get the phone to come onto the screen (none of the right hand numbers seem to work at all). Does anyone recognise these symptoms and/or could they just show that my SX-56 needs the ROM RE-flashing? I should add that pressing the Master Reset button with this ROM in place seems to make the phone shut off and then when you restart it, all of the data remains in place. I wonder if there is any possibility that the XDA ROM has prevented the reset button from working normally?
A user on another forum said that to him, '"Sounds like the digitiser is up the swanee - have you tried recalibrating it?"
10-12 vertical black lines started appearing to the right hand edge of the screen. Sometimes they are there, sometimes not. THere is usually at last one there somewhere. At about that time the screen stopped responding as I mention. Today the left third started displaying the same veritcal lines, though spaced quite far apart (about a millimetre). Screen doesn't APPEAR cracked: Does this sound like a digitiser and if so, how do you recalibrate it please or is there a link to somewhere on the XDA site which I cant find which might tell me? Or could it be the cable is loose in the circuit board? As you touch the lower right hand corner of the metal casing where the vertical lines are, those lines flash (the right 10 or 12) on and off. And every coloured bar everywhere on the screen or word of text has vertical lines on it (the white parts don't)??
Someone on ebay has said that his phone "fell from my pocket and onto the carpet and the screen cracked, I then used it for about a week" "I sold the screen to someone cause the wanted the touch pad part of the screen for there phone". and wonder what it was he sold or which part can be replaced on it? IS there a touch part and a screen part on this phone?
To be honest, itsounds like you have brocken a connection somewhere between the LCD and the gfx output, probably not possible to repair yourself.
I wonder where the break would be?
I thought that might be the case: I wonder if it would be worthwhile trying to get another screen?
I should probably try to take the unit apart and see if some break somewhere can be identified if it is a break as opposed to some electonic part having failed. It SEEMS to be in the lower right hand corner?

SOS - Hermes works fine just that there is NO screen!

Really need help here,
My hermes suddenly decided that visuals are no longer needed.
That means the screens stays off all the time (yes even in bootloader mode).
It works, receive calls and flashes roms but in no situation can I see anything on the screen (pitch black screen).
I've got no warranty so I took it apart and checked each cable and connector - no issues were seen. I tried changing SPL-s, RUU, Roms all worked but left my tytn with that black screen.
Did anyone see this happen or has any advice?
This sucks big time :-(
No one? Oh man, I guess it's dead then :-(
Last bump before giving up and throwing it away - please?
send it to me if your gonna throw it away : - 0
I've given up on mine as well. It has white screen though. Where do I dump this thing?
If it is out of warrenty, I would take it apart as is sounds like the hardware, check the connections to the LCD. Does the backlight still work, or if you put it in strong sunlight, can you see the LCD working?
My Hermes had a white screen also. I found that if I squeeze the bottom right hand corner whilst resetting it would sometimes work. It seems there is a chip on the switch board that needs the right ammount of pressure on it. I think it was a design flaw as the herm200 and 300 are different. If applying pressure works and you are confident enough take the hermes apart and put a couple of small pieces of plastic or paper between the front buttons and the small square chip on the switch board. This worked for me.
The service guide is available if you google. Let me know if you need more info.
As for the black screen that sounds more serious sorry not seen that one.
what are you guys willing to sell your pdas for? Mine fell in a puddle and i need one for parts. The white screen might be fixable the first couple of times but then it dies off for good, the black screen i've never heard of.
So if you want to sell for a reasonably cheap price let me know, i can buy a new keypad online for $50. So around there would be nice!

I just tested this on mine and actually got some results.
mines the opposite though, it will NOT work with any pressure. I left all the screws loose for that board under the buttons, and left the LCD assemble screws out on that end and it works, But if I press the keys it whites out again and won't come back until I repeat the dis-assemble/re-assemble
I had a similar problem but this was after someone dropped mine on the floor. The screen would just be white screen, while everything worked. If I pressed the bottom right of the phone it would sometimes come on and stay on for a little while but would eventually always go to white screen.
I did manage to use the phone but had use a program called Net Control which allowed me to control the phone over WIFI with the phone screen shown on the PC. Got the phone replaced in the end by the people who dropped it.
i got the flex cable and my phone still has the white screen problem....wtf///

Cracked LCD or whitesreen?

I have read a few posts about the white screen issue and some seem to pertain to my problem and others don't. My screen is white 100% of the time from power on to power off. So I can't seen anything when it first boots or comes out of standby mode or any thing else. The only way that I can get the screen to be anything but white, is to hold it in my left hand with the keyboard slider bottom left corner of the phone pushed up against the base of my thumb muscle and my other fingers pushing on the bottom right corner or the phone on the screen slider. Sometimes if I hit it in the bottom right corner then squeeze it I can get it to work without tiring myself out from squeezing after 1 minute.
Seems to be a pressure and angle thing i think. The phone has been dropped on more than one occasion. Ten tops. Sometimes when I squeeze it i get lines from left to right, then fade to white.
If I put the phone on 65-90 degree angle from my eyes I can see a little black mark at the top of the screen under the C of HTC. That is what had me thinking that it was a cracked LCD.
Any help would be greatly appreciated. Phone is still under warranty, but would rather not be without it for the 6 -8 weeks I was told it would take, only to find out it was a cracked lcd and they won't fix it.
I believe you have to open it. Try to connect every single connection again.
I Had This
I had this problem when i dropped my Vario 2 the screen cracked and was all white, when i went on ebay and bought a new screen I took the vario 2 apart and replaced the screen BUT the ribon connector that plugs into the board was not quite in so when i re-assembled it i just got power and white screen.
There are a couple of little lugs on the ribon cable and i though that once they were butted up to the connector on the board that it was in properly. BUT the lugs actually needed to be pushed that little bit further and slide under part of the connector. BANG it worked fine.

Either send back and keep warranty or try the several solutions posted. I myself am pretty sure I found the correct solution and I posted it in the appropriate thread.
Thanks guys, I think I'm going to try my luck with sending it in. Will probably add a link to the main whitesrceen thread so hopefully I get no hassles. Will post back When I get it back.
I had a similar problem and voided my warranty because I don't have a spare device... anyway, here is where I found my solution.. http://forum.xda-developers.com/showthread.php?t=321163
Good Luck... My phone is still working fine....

Screen display scrambled fades to white - ideas to fix?

Hi, i have been experiencing a screen display problem.
When i power on the Hermes the screen does not power on.
If i then place the Hermes on a hard surface and press down hard on the long sides at the edge of the screen i can make the backlight and display appears.
However, if i release this pressure the backlight remains on but the display will become scrambled. The scrambled display is variously showing white noise, scan lines, mispositioned graphics, and ultimately fading to white.
Also, if the phone rings the audio is distorted and crackling.
I have dismantled the Hermes as far as removing the housing for the LCD from the rest of the phone. I then opened up this housing and disconnected / reconnected the LCD flex cable that is by the very edge of the housing. Then reassembled phone. No improvement was made, in fact the display issue was made more tempermental!
However the phone stil works as i am using it at the moment as a 3g modem for my laptop.
But it is extremely frustrating / near impossible to use it for any other purpose in this condition!
I am wondering as to what the problem could be and how i might solve it?
I am thinking that the problem must be due to a poor connection / oxidation / dry solder somewhere.
I would appreciate advice as to what i could do to solve this issue myself.
Next steps???
>>> Would there be any use in spraying a little WD40 into cable contacts?
>>> Someone has suggested passing a heat gun over the PCB to bond any solder that may have cracked.... Although i am sure that this is a trick that can work with old PCBs that he plays around with i am not so sure that this would be such a good idea on the flimsy multi layer boards in the Hermes.
Let me know what you think of these ideas...
white screen
Hi..not sure which version of the hermes you have, but this has been a common problem for years. My Cingular 8525 did the same thing. I finally figured out while placing the phone into a desktop charger that it was putting pressure on one lower corner of my phone and it would go white. It got to the point any pressure on it would cause the screen to fade to white. I contacted AT&T tech support about it and even though fone was out of the warranty period(over a year) they sent me a refurb ATT branded 8525 at no charge. I've had that one now close to two years with no problems.
Hi Oleschuldad, thanks for your reply. I have the Hermes100 branded as the "ORaNGE SPV M3100". Yes i have read that the white screen issue is a major blight for the hermes phone. From what i have read It seems that there are numerous causes and the problem can be difficult to trace to a specific component. The problem that my phone has is the opposite to the what you had with your phone. In that i must EXERT PRESSURE on the phone to be able to read the display. The indication is such that i am certain that it must be the result of either loose connection / bad solder / corrosion somewhere.
Think that i will get a can of electrical contact cleaner spray and clean the contacts on the flex cables.
Looks like corrosion is definitely an issue in my phone as there is some green oxide on the round watch type battery that sits on the main board next to the contacts for the main battery.
I will have to strip the phone down again at the weekend.

[Q] D800 Intermittent "Static" Screen

I've got an issue with my D800 that I'd like some confirmation on. Since this afternoon, it's intermittently had a static filled screen. I've found that if I tap it a few times, it comes back to a normal screen. A few times, the screen has come up off center from what it normally is.
The digitizer looks to work 100% of the time. I'm confident that this is a hardware issue in that, if I reboot the phone, I have that static all the way through, from where the boot logo should be to my home screen.
My question is this: Is it the LCD or just the ribbon connecting the screen to the mainboard? My personal feeling is that if it were the screen, then it wouldn't intermittently come back. Also, reseating the ribbon is cheaper than replacing the LCD.
Any thoughts from those that have had this happen to them before?
Hello praetorzero,
Can you describe more about your "static" screen?
Do you mean like a noisy screen like old television displays?
Do you mean that one image like home stays the whole time on your screen?
By these both things you can try to reseat the ribbon but watchout that you don't move the ribbon too much because it can get bad.
It's true that it's an hardware issue. If you have warranty you can RMA it to let it be repaired. If you don't have warranty and the ribbon reseating doesn't work then you maybe can buy a LCD+Digitizer for like 80 euro or you might just sell your phone :/.

I can't post links yet, but let's try this anyway:: i.imgur.com/tPFHxJb.jpg
This isn't my picture, but this is exactly what my screen looks like when it's not working. If I rap the lower portion of the screen with my knuckle, it will either go back to completely normal or go off-center with the lower half of my homescreen represented at the top of the screen and the lower half static. Again, the digitizer works in the expected location, because I can still unlock the phone with my typical swipe.
Unfortunately, I bought this off of eBay, so there is no warranty. I'm on my own.
