Replace the battery
I had the same problem after my mda ii went through the washing machine. Replacing the battery fixed the problem.
thanks guys for the replies , further my XDA had been properly dried and cleaned but now the problem is that the machine doesnt operate further than the "ALIGN SCREEN" setup where one has to tap the screen at four corners and the center one I tap the screen i return to the same screen as ask to tap the screen again.
Will flashing the rom serve any purpose or is it aa hardware problem, rest of the device seem to be ok even the bluetooth light flashes when i turn the XDA ok. But not able to get i any further from there.
So what do the experts have to say, Please reply.
thanks again
well, mine had very hot coffee poured all over it.
my suggestion to you would be, dont turn it on or place the battery for at least 3 days if under normal drying conditions only.
or if you know how to take it apart, spray everything with contact cleaner, it will dry up immediately,
then cross your fingers and hope nothing shorted out when it first went inot the water.
strategy is - wait - dry- wait - test - dry some more - spray contact cleaner - dry - test - until such time it works. coz some moisture might still be present and causing a little bit of short circuit.
It sounds more of a hardware issue than a software issue and you may have to take is apart to fix it.
Try two things, Number 1: (You need to use some latex or vinyl gloves if you need to take your unit apart). You are going to need to check your digitizer connection to the motherbaord, make sure you don't have any mosture trapped in the ribbon lock and make sure the entire front part of the digitizer is flush against the inside case edge. Number 2: Have you seperated the digitizer from the LCD yet? If this thing was in water the slightest spot of moisture will disrupt the very small electrical field between the digitizer and the LCD that recognizes the stylus taps. Abosolutly nothing should be present between the two and also around the white or grey strip on the inside of the digitizer for it is also a contact strip. You can use a lens cleaning cloth to clean any dust and moisture from the inside of the digitizer before you put it back together with the LCD. Being I worked on about 150 toshiba e750's that suffered sprinker damage in a fire, I learned quite bit on what makes a Pocket PC tick. Good luck with getting it working.
the same
I had the same problem 3 or 4 years ago with a HP Jornada 680 (handledPC). I must unfortunately say that I could never get my touchscreen working back again. Perhaps if you could change your screen for a new one, or at least one that always worked (some are sold around the www, even a few by members here if i remember).
Good luck

the stylus is working as the sceen responds to the tabs, but the process of calibarating the screen doesnt finish and keeps on repeating. and it asks to align the screen again.
The digitiser is working but the software doesnt seem to be working...
what do you have to say?
and thanks for the reply
guys thanks for the reply
but no luck... is there any sofware that can check if the components are working and ok, or simply what should i do. The info about the problem in a nut shell is
First the loading happpens with the O2 screen then the "Windows mobile screen says Tap the screen to setup the pocket pc" Then when i tap the screen next screen comes saying "ALIGN SCREEN" with a crosshair in the middle of the screen when i tap it with the stylus it moves till all four corners are tapped which crosshair point to. But now the problem begins.
The same screen repeats and asks for the same procedure again and again and again And the Xda processing doesnt move further.
i even flashed the ROM but same thing........
no luck
HELLLLLLLLLLLPPPPPPPP!!!!!!
REPLACE THE BATTERY
Have you bought a new battery yet?
Like I said above, my MDAII went through the wash. Just like you, i got the align screen process followed by a spontaneous hard reset. I bought a new battery, charged it up in the cradle overnight, then popped it into my machine. Good as new.
Don't mess with the software until you try a brand new battery.
Cheap and effective.
Hmm, the touch screen is responding to taps, but maybe its a bit 'offset'.. I mean maybe when you tap exactly center, it will receive your tap to be a lot more offset to right, left, up or, down.. Cos that's what making the 'align screen' asks you to realign again and again..
Hi Tanvir,
I want some of the others to advise on what I am suggeting. On my xda I ( which I own as well as a Blue Angel) we are able to put it into boot mode and press the "action" or was it the "contact" button to get it into test mode. Being I don't own a Himalaya but I would guess that they would have that function too, and in that function it has a test for the aligment screen which it might be able to align in the test mode away from the OS running. If someone has the tip for helping Tanvir of getting his unit in to test mode, Please someone post it for him. Also being I don't own the XDA 2 if anyone has anything to add on my suggestions, the floor is open. let me know how it's going Tanvir. Cheers.
Shane
I'm sure Tanvir's digitizer is no more...
Go to www.ppctechs.com and purchase a new one... not that expensive!
Good luck!

Hi shane,

I wanted to change the touch screen on my QTEK 2020 and I bought a new one a few days ago. I opened tha PDA, but when I tried to pull the touch screen off, I damaged a slim orange cable on the back of the screen. Specifically, I pulled a black sticker and it took along the two cables that were on the circuit on the screen. I don't care for the touch screen's cable, but for the one of the screen. I have scratched the insulation on the cable and I have a question. If I just put over the circuit the nakes cable and glue it a little belower, would it make connection? Or have I to solder it? And How am I going to soldier a cable like this that's naked from the side that I don't see when I put it in place, without even melting and damaging for good the screen or the cable itself? I have some pics, too for you to see and understand what's going on. Please help me, as I am a young man with prospect and I want to learn things like this and do stuff more than the usual.
OK, I couldn't wait for advice so I soldered both cables. The screen turns on and it needs to be aligned. I tap the screen, the touch screen works, but when I finish the alignment, it starts from the beginning, the cross in the center. It asks to be aligned constantly. I haven't assembled the PDA, I have it like the pictre below. Is this the problem it doesn't start, or do I have to put the touch screen somehow differently? I have it centered and tried to align tapping a little upper, lower, left, and right from the cross, but nothing.
Please HELP!!!
OK, no worries! I fixed it! It took me all evening, but I'm completely satisfied. Solder this, solder that, make a bridge because a connection was damaged with all the scratching, but it worked!
cong. dominator happy that you have finally fixed it :wink:
Thanks Kbantikos my boy! And here's the bench and the heat tool I used! That's the only that I have. No doubt it took me 4 and a half hours to complete.
Congratulations! I'm not kidding, saw a lot of "homework" results, in some cases, display was damaged beyond repair.
You get the working display, so you are lucky .
Thank you, my friend! I didn't believe my eyes when it booted! It still works fine, even if it fell off my hands one time!
my touch screen is really quite dull / lacks brightness even when on the high setting
i've aquired an XDAII that isn't working but i know its screen was bright when it was working
my question is: what do i need to be looking out for / be carefull of when i replace the screen
what would you do differently?
thanks
Larry
You'll definitely have to look for that orange cable that's not of the touch screen. on the back side of the screen there should be a black sticker. When you try to pull it over, it takes the cables, too. So pull it from the side of the touch screen's cable only. You are gonna need to solder the new touch screen for sure, just placing it won't work. Scratch the side of the cable that's going to be placed on the circuit on the back of the screen so that the metal contact on both (touch screen's cable, circuit) is naked. Put solder on the circuit's contacts. Then put the cable on top of the circuit, but a little lower. Now, burn the solder holding the cable steady and connect that way all four contacts. I hope I was of a little help, observe my pictures and good luck!
Just about to try this myself.
Touch screen bought from - http://stores.ebay.de/hitechhk. Arrived within 1 week.
Removing the black tape on the back of the screen, even very carefully, pulled off both the connections for the touch screen and another connector (the back light I think)
In hindsight would recommend only removing the tape around the touch screen connector.
As soon as I find a small enough tip, will resolder everything.
Detominator7, how did you change your digitizer? cause i need to replace mine too, but the seller is talking about soldering it. i already open my pda and all i can see is there is only plastic cable. how do you solder on plastic?
Your touch screen might have a cable that plugs into a hole and does not require soldering. You know, like the fans we use on PC.

What kinda adhesive do they use on the back of the screen
I'm talking about the clear glue type adhesive on the back of the screen in order to hold the ribbon in place
here's a pic of what I'm talking abouthttp://blog-imgs-3.fc2.com/i/n/u/inuchanbt/CHT9000_dismantle12.jpg
The gold/copper ribbon glued to the screen
had to replace my brothers screen about 3 times and now its barely stickin
it's a kinda like double tape. u can find in office stores
I hard reseted my O2 XDA II & I had surprised the screen aligning can't be passed.
Can somebody help me with ROM Flash or maybe some hardware tricky?
I use WM5 from C_Shekar.
PM me if anyone replies this message.
Thanks, Berns.
Ok so I have the fabled white screen issue on an 8525. When it first occurred I searched and read all the write ups, decided I had the ribbon cable issue. Took it apart and simply unplugged and replugged the ribbon cable with great results, no more white screen.
I repeated once when it came back after being bumped around, again with positive results...but this last(3rd)time instead of it working I now get white screen 95% of the time. I re-notched the sliders the first time, and last time.
During the 5% it works I noticed the charge light would correspond to it going white.This never happened before...
Example:
When OFF - Connect charger, Red light for 1 second, then nothing=White screen from power on
When OFF - Connect charger, Red light for 1 second, then orange charge indicator = normal startup
When ON and Working - Connect charger, no light, no charge - reboots to white screen
When ON and Working - Connect charger, orange charge indicator, reboots normally.
There is no heat or noticeable pressure on any parts, everything seems to fit normally.
It does boot normally with screen white.
Any ideas? I really don't want to give up on this thing, is there any hope? or just ebay it for parts?
Thanks
-Nick
same problems here, if someone could just tell me what parts to order, cause I have no warranty (ordered over ebay). I tried both the instruction that has chinese fonts on the page , and other from R&R, no luck, white screen all the way..
I had the WSOD and took it apart and reassembled a few time. The 3rd or 4th time the screem came back, but now it is shifter to the right around 1/4" or so. I mean there is just white along the left edge, then the normal screen/color starts and is cut off on the right.
Does anyone know how to correct that, is it related to the same flex cable or is there something else I disturbed?
mine will fade to white.. then i just push the power to put it in standby, then push power again to wake it back up and back to normal.. it rarely does it but still annoying...
If You Ordered From At&t
I had this problem about 2 weeks ago!!!!
I thought it was a fluke!
Anyway, walked over to 43rd and Lexington (NYC FOR THOSE WHO DON'T KNOW THAT MANHATTAN IS THE CENTER OF THE WORLD)
and they gave me the EXCHANGE HOTLINE for at&t.
I called them up, told them my screen is fading to WHITE and the lady sent me a new or referbished phone.. i dont even know.
Just so you know, i ordered my phone on AMAZON with a new activation. its covered under the MANUFACTURERS warentee for a full year from the date of purchase... so is the REPLACEMENT PHONE... but not from the date of replacement, just the date of purchase.
did anyone get deeper into this yet? I got a 8500 (need those without camera) from ebay USA, already with white screen. After reading here, that this is mostly an issue with connectors, I bought it, disassembled it and reassembled it, though still white. Should I give the contacts a treatment with contact-spray? (there's a tuner spray that doesn't leave residues) Or is there something broken within the ribbon cables? Seller said it has been dropped (but he also said, he didn't want to open it, while it clearly has been opened, one screw missing and warranty seal gone). It ssems to boot up normal otherwise, I hear a sound after the boot process, so probably this isn't a software issue?
Edit: another thing I noticed: When I run it without any keyboard connected at all, it's also white. I then connected the dpad again, and I could see a hint of the at&t logo in the lower part of the screen. When I pressed around on the back of the dpad a bit, all LEDs would go on/off... Sound to me like the dpad has gone bad, possible?
Edit II: Got it. Using a 20x eyeloupe I found that the PCB of the DPad is broken under the little chip on it. Now I just gotta find a dpad here in germany, but I assume those Hermes' are all equal...
hello
where can I get manual (if there is one) for disassembling hermes. link in wiki does not work.
thanks
this worked good for me

Anyone know if this applies to the 8125 as well? I've got a flickering white screen. I had dropped my phone a few weeks back and cracked the LCD. Replaced it with an OEM LCD - it worked fine for about 2 weeks and then just suddenly went all white. Phone still works, I can still get calls - just can't see who is calling.
I don't recall that the wizard had the same problem... Though from a logical point, it seems that there is an issue behind white screens and the thumbpad being responsible for it, so it may well be the same thing. Perhaps just disassemble the wizard (there should be a howto too) and check if theres a similar connection from mainboard to thumbpad circuit.
Is there a disassembling manual for a imate k-jam that anyone knows about?
Here's a website with a video manual i found useful...
http://viralelectronics.com/category/howto/page/2/
Figured out the problem...
The only reason I figured out the screen goes blank is because the motherboard loses connection with the screen when you slide the keyboard out...try this out and see if the screen comes back...
put the screen on sleep mode (no white screen)...then slide out the keyboard and tilt it a little hard after pressing on the screen and put the power on. if it doesnt work try again it might take some pressure and power to make it work...be careful not to put too much power but as far as I went, it's a very sturdy cell.
alternately, slide out the keyboard in sleep mode, and press all the buttons really hard and then try to press the power button (press more towards the space bar because that helps)...if any of this works and the screen comes back on even just for a second...follow the following
Go back to the person who gave the link to the site with opening the HTC instructions and follow through and clean the whole phone up from dirt around the screen and such...you dont need to put those rubber things or whatever it says to put on the screen...then when you are putting it back together, press hard on the wire connecting the touch screen to the motherboard. I suggest sealing it with a good tape...and then you are good to go! I did it but it had a few glitches...the screens contrast sometimes goes awry but it is still visible and responds to touch. Also, the physical buttons work as well!!
Good Luck and do it at your on risk.
Have any of you tried this? http://forum.xda-developers.com/showthread.php?t=321163

i tried this and it worked for me. i also pressed alil hard around the d-pad and heard a pop. i think it poped back into place.

i still have this problem.
fixed my wsod
I noticed a few days ago my 8525 screen went white, rebooted and it went away. Today it came back, but would only go away for a few seconds and then back to white. After reading some forums I decided to check the connector. I took the phone apart following this site as a guide. I removed the connector on the board side and cleaned the contacts with a qtip and denatured alcohol. Phone has been perfect for the last few hours, no more white screen of death. I didn't mess with the connector on the LCD side, just the board side. I'm a computer tech and I found it quite annoying to disassemble, but I managed without causing any damage, however, I'd rate the job at about a 8/10 as far as technical ability.

i agree that this is one of the first things to try in curing the white screen issue. Others may find their problem runs a little deeper and the contacts on the d/pad chip are broken. An improvised cure which may not be very permanent is to place a little padding on the surface of the chip as described here:
http://forum.xda-developers.com/showthread.php?t=321163
If you have appropriate heat gun equipment you can re-flow the solder on the d/pad daughter board - but remember to remove the sticky key pad layer or you'll cook it!!
I regret that I'm closing this thread because we have several "White Screen" threads and the questions and answers are being spread all over the place.

Hi all.
I have a strange hardware issue with my hermes device.
Suddenly the screen started to *vanish, meaning when turned on, it turns all white/shows little stripes.
I figured that there must be a defective contact from the board to the screen.
I took the whole phone apart already, and reaatached all plugs/contacts.
This helped for a few days, but now I start getting the same flickering again.
Did anyone in here run into the same issues with this device?
If yes, how did you fix it? What can i do, to get the contacts stay in place?
Thx for your advice,
trial
Hi,
The Screen LCD has a black ribbon at the back which attach's back to the main board. It could be:-
(1) That the ribbon is not alinged or fully home in its cradle. If you prob the cradle with a screw driver (gently) you will find it opens upward and thus you can remove the ribbon, clean then replace and close the cradle lock.
(2) More likely that (hard to explain but if you tinker you will work this out) the componets around the camera include a power regulator to the LCD display. It is held in place by the case and if not seated correctly prior to closing the unit will move and thus the LCD losses nearly all abilty to be seen & sometimes causes the flicker you describe.
Hope this helps. For novices be aware that tinkering often leads to breakage and while I'm happy to break things you may not be and thus I'm only another blind fool leading you on a path of destruction !! lol
A friend of mine brought me his Wing to look at for him. If I turn on the phone on it boots up and the screen looks just fine. When I slide the screen opened to use the keyboard the screen freezes and when I close it again it gets all jumbled up. There are lines going through it and I can not make out anything. The phone isn't locking up at this point because I can press menu buttons and other hard buttons and see the screen react, I just can't tell what is happening.
I assume that this is a hardware problem. I was thinking that the cable that connects the screen may have been jarred loose or damaged in some way. If that is the case do you think that it would be as easy as opening it up and repositioning the cable? I don't have any experience with this phone specifically so I don't know if this is a common issue.
I was also wondering if it is possible that this is just a software issue. Maybe the function that rotates the screen for use with the keyboard is messing up and jumbling the horizontal and veritcal lines when going back and forth. I was thinking about doing a hard reset and seeing if this clears up anything. Any thoughts?
I appreciate any help. This forum has always been there when I needed help in the past. I'm sure somebody out there has much more experience and knowledge that I have and can lead me in the right direction.
Thanks for any and all help!!
Update...
So I went ahead and tried the hard reset first hoping that it might be a software issue. I am now at the screen that says "Tap screen to setup your Windows Mobile based device." No screen touches are being recognized. This seems to support my thoughts that there is a loose cable or bad connection. Agree?
I just slid the screen opened to see what would happen and it faded to white.
Yep, if my experience with the Wizard tells me anything, the flex cable from the main body of the phone to the screen is either loose or damaged somehow. Even a small nick or cut into the flex cable will cause it to stop working correctly. I would hunt up the Herald service manual and take your device apart and see what you can find.
Thanks ... I downloaded the service manual and plan on taking it apart. I have to make a run to the store though and buy a small enough Tork screw driver. T5 or T6 I believe.
Thanks again, I will post with my findings when I get going on it.
now what?
So ... I have the phone completely torn apart. I do not see any loose or damaged cables. It was dirty inside the phone but other than that everything looks just fine.
Does anybody have any advice as for things to look for, that might be causing this problem, while I have this thing torn apart?
