*White screen problem* - JAM, MDA Compact, S100 General

Hey guys,
I know this problem has been addressed before but none really leading to any resolve so I wanted to bring it to the surface to find anyone who actually has a solution.
I recently purchased a second-hand unit and found that it was working fine for a week until suddenly I couldnt hear voice in my calls. So I opened the unit and found that the contacts were off and fixed that but when the unit was reassembled, the screen turned white. Now I tried moving the ribbon connector of the LCD screen around and got different results: a black screen, a half black/white screen, a scrambled color screen. I hear that some say you can just dab some contact cleaner onto the contacts and it may work fine. Has this worked for anyone? If so where can I pick up a bottle? Are there other alternatives?
Please let me know.
Thank you.

just hit and trial may work for you as it did in my case.(i got a scrambled color screen)
just disconnect the ribbon wire and connect it again being exactly parallel to the slot.
ensure that it is pushed inside properly.
do it till your screen is tired of being messed up with colors.

tried that for an hour and I can't seem to get it right.
Does anyone know of a solution that can increase the connectors sensitivity?

Personally, I use rubbing alcohol on the very tip of a tooth-pick, then dry it off with a soft cotton swab.

Not functioning correctly after replacing broken screen. Help!

A few months ago the screen on my SPV M600 took a knock which cracked it pretty badly, to the point it couldn't be used. I've rebuilt two other HTC phones in the past so felt fairly happy buying and fitting a replacement screen myself, along with the fact Orange wanted well over £100 for repairing it!
I dismantled the phone back to the screen to find it had a gold LCD cable and bought a new one on eBay.
I've now tried fitting the screen which works perfectly when the phone is still appart, but when I put the casing back together the screen goes blank. The exact point it happens is when I'm clipping the side of the phone with the volume control into place. The screen gets very bright as if the backlight is either getting too much power from somewhere or the backlight setting isn't taking effect. If I set the backlight to minimum it's most noticable as it goes from dull to full brightness when I apply pressure between the screen and board on that side of the phone.
I've tried sliding a piece of card between the screen and board to see if there was something touching that shouldn't be, but it doesn't seem to make much difference.
If anyone could offer me any advice on how to solve this I'd appreciate it.
Thanks.
I think I've solved it, I hadn't put a layer of the copper from the back of the old LCD onto the new one. It seems to be working fine now.

Wizard Display broken?

Hi guys, I need some help here. I literally threw my wizard out of the window shaking out my bedsheets and it dropped three stories into the backyard.
When I turned it on again (the drop had opened the battery case), at first the screen was bright white, then turned darker and darker showing some sort of noisy stripes (static, not moving). When it goes into standby and is turned on again from there it does the same thing.
some facts:
- there is no visible crack in the display (neither from the side, I disassembled it)
- all buttons and the touchscreen are still responding (u can see that because the background lighting responds to them)
- the wizard is still accessible via usb
- I don't know whether the phone still works because I can't enter the pin w/o display.
It seems strange to me that the display should stop working while the touchscreen and the background lighting remain unhurt. I am thinking about replacing the display (only available together w/ the touchscreen and bg-lighting), but I am afraid that it might rather be a problem with the communication between the main unit and the display, even though there was no visible damage there.
Does anybody have experiences with that kind of behavior of the display?
Is the display that vulnerable that it breaks before the rest (light, touchscreen)?
I didn't find any cases similar to mine in the forum. If there are and my questions would be answered there, please direct me there.
Thanks for the help

Try taking it apart, the force of inpact could have made a connection loose.
Disassembling I disconnected everything possible. Next thing would be to take apart the display/bglight/tscreen.
did you mean that? looks pretty fragile to me...
thx
yeah, I wouldnt mess with the display .. lol .. I meant a connection somewhere inside the device... like a loose ribbon or something
Yeah, seems hopeless. Guess I'll have to buy a new display and hope it works :-(
I'll post again once I got some results...
Problem solved
For the archive:
I exchanged the display and apparently only the screen was broken and the rest was unharmed.
I'd also like to add that two days ago (1 week after I repaired the thing) I dropped a plastic bottle on the phone in such a stupid angle that it broke the touchscreen. the next thing I will report here is whether it is possible to exchange the touchscreen only by doing some soldering.

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///

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.

In-Call: Screen turns off and unresponsive

Hi everyone,
I recently changed my HTC's Aria digitizer because it was cracked.
During the process everything went smoothly however after that I have discovered that when a person calls me or when I call someone the screen turns off and never gets back to normal if there is no other "stimulation" such as putting the phone to charge for example.
My guess was there was a problem with the sensor so under settings I chose to keep the screen awake at all times during a phone call, still, I am having the same problem.
The weird thing is that sometimes when I remove the battery cover everything works fine and the screen keeps on, but sometimes not, so its not a constant rule..
I may have messed up something during the replacement of the digitizer (its just the glass not the lcd) such as removing the sensor and not placing it back correctly but the thing is that I dont really know the components of this device so Im not sure what is what..
If anyone could help me to understand the problem a little bit I would really appreciate it.
Thanks in advanced..
Anyone? Please
The sensor is right above the AT&T logo. If the little rubber ring isn't perfectly aligned with the sensor, you will have this problem. My wife's phone has a similar problem and it is fixed (temporarily) by firmly pressing on that corner. The adhesive strips have failed and I am looking for a source besides "Repairs Universe".
Thanks a lot!
I will try to take apart my Aria again and see if I can align it correctly
thanks again
glad that i found this, having same issues with my wife's aria, will give it a shot
