Some Problem in Display!?

I had repaired my hinge once, afterthat, I installed the new i-mate ROM. The display become strange since then... It is the most strange when displaying pictures. It looks like the entire picture has been digitally modified by color blur?! (I'm not sure how to discribe it) It just like a lot of areas is rendered by the same color (the source picture has far more complicated details, but it is all been cut) And it is not a 3rd party software problem...
I assure my-self that this is not the ROM problem, I installed the old O2 ROM, and the problem still exist....
So can u guys please give me some advices?
Shall I send it back to repair? Could a hinge repair done that damage?

Check the connectors have not come loose first, then check the cable in the hinge. What did you do to repair the hinge?
Richard

I did not repair the hinge by my-self. I send it to Lemel repair station. And I don't know how to check the hinge or the cable on my own...
What I want to know is: Is this a hardware problem or a software one...

The set of cables if broken, cannot be re soldered or repaired...u will have to go in for a new set of cables and that is quite dearer around 15-200 USD

That's a lot for a cable :shock: . I have repaired a jasjar that had sheared using an m5000's intact cable to map out a circuit plan of all the pins. I'll upload a diagram when I find it again.

UNIVERSAL : need a Coaxial Cable Pre-assy replacement

Hello
I am new on this forum, sorry if this type of question has alreday been answered.
I've got a UNIVERSAL/ SPV M500 and the Coaxial Cable (linking the screen and the keyboard) has been twisted and is damaged.
Where can I find/buy a spare part to replace it ? the reference number is 73H00233-01M (Coaxial Cable Pre-assembly) as indicated in the service manual.
Thank for your help.

Hey,
If you find it let me know, I need one two. Actually these are two cables the Coaxial (Display) and Coaxial (Functional). My screen goes white in landscape mode and I confirmed it's the cable by disassembling my machine. However was unable to find that cable Will let you know if I find it.

Me too.
I am getting odd touch screen errors and think it can only be the cable.
If anyone knows of a supplier, please post here.
Has anyone tried contacting HTC directly?

I have been having the same problems as you guys. my uni have been getting "white screen of death" for about 6 months now.
I am going to take out the cable and try and fix it myself. (fingers crossed)
I will let you all know how it goes. I felt £60 plus vat and postage was a bit steep.

coax cable
Fixed it!!
I took apart my uni down to the last screw, and rebuilt it.
In the process I did find that i am missing an antenna in the back, it should have 3 but only has 2. oh well it works.
The 3rd antenna is for 3g and i am not on 3.
Anyway back to my uni.
The coax conectors where a little lose, so after a good clean in a solven cleaner and popped back in to the conector holder, after playing for 20 mins I found that they poped back out verry slightly, just enough to make the screen go white and not function.
So the solution is to make sure it does'nt come back out.
ok.
well I have as a tempery solution put a tiny bit of foam on top of the connecter and held it in place with a bit of tape.
If this works for longer than a month then i will solder the cable down.
Touch wood it seems to be working. I will try and get some photos done tonight

Because of the Job I do, I have an earthing band to connect the phone and me to the wall, and put the phone on an anti static table cover. All is good so far. I am looking at Feb to solder (as i have some leave in). There will be detailed photos and description.
Untill then........

Good done man go ahaed, and plz try to post the photos.
Another question, my universal some times lost its external speaker sound, so i cannot hear the rings, when i press on the back of the device, exactly on the battery cover in the middle between the two dummy holes and the usb port, it works again. Do u think that this is due to the coaxial damage also, even i don'y have any problem in the screen??

I have disassembled my uni and checked for all connections, but there was no improvement. I can confirm that the disappearance of external speakers sound is not due to co-axial cable. The proof is that i extracted my main borad from my uni and implanted it in another one, i assumed that the problem will be rsolved, but the same problem still exists. Ok, now i can disassemble my uni for smallest piece, but any one advise me where is th connection part or the piece that causes that problem. Again a brief description of the problem:
when there is a coming call, i cannot here the ring or it is sevrely intermitent, also when i play any WMP file, i cannot here the sound, if I press firmly on the base or around the keyboard the sound comes again and may last for a few minutes or disappear after another press. So, there is a lose part in the main board i think that needs fixation, but which one????

Hi all
Now it takes me more than a month to upgrade my JASJAR due to a lot of problems I faced during this upgrading adventure… anyway, the last problem I still have is that after upgrading the screen goes crazy, I mean if you press on the screen the colours are mixed for few seconds and then its ok but at any time I touch the screen again the same happened so you can imagine what if I am going to dial a number or write a message …. So can anyone advice me what to do? …
The rom version is 1.13.82
Radio 1.04.02
Extrom 1.13.188
And I think the bootloader 1.00 and I don’t know why I feel that the bootloader is the reason ... I made a deep search but I couldn’t find problem like mine

Sitting next to my M5000 and all of a sudden the screen turned on but was white!
Following your lead I found that the first i.e. 'underneath' connector was not fully home. A little push and all is well.
Took the time to pack out the housing for the stylus to stop the little blighter escaping whilst in there.
Thank you for taking the time to post gingerchristopher.

Flex Cable change gives errors PLEASE HELP

Hi dear developers!
I got a Touch Pro 2 from a friend, it's a GSM device he bought in Germany (O2). I changed a few parts but messed the main flex cable. The part from the power button is not connected anymore, a clean cut through, no repairs possible as far i think. So i bought a new one over ebay from Hong Kong. The seller told me it's for a GSM device BUT the cables do not look the same. The production date is 2008 and the damaged one was produced 2009. I built everything together and now the big surprise:
Phone boots normally but when the Home screen appears, it is always in landscape mode. No matter if the phone is closed or the keyboard open. I can only change the screen over advanced tools, but after soft reset again only landscape mode. The buttons for calling also do not work (those two down on the screen when you want to call someone or end a call ---> no reaction).
A hard reset and new ROM (energy) didn't change anything. By the way, the keyboard only fires up after pressing a button. Before it automatically lightened up after sliding.
What the hell is wrong now, did the send me a CDMA cable? Where is the difference ? Please help me i do not want to spent another 30 bucks again for a proper flex cable.
Edit: I disassembled the phone again and took a closer look on the flex cable: the lower part (with the LCD connection etc) looks quite same except for 3 or 4 transistors and their position on the PCB. The upper part with the earpice looks way different. The positioning of the single parts is not the same. But how can that interfere ? Guess there is no problem with the mainboard or the LCD (which is brand new).
Here are some pictures
h**p//img28.imageshack.us/img28/1514/image2sh
h**p://img849.imageshack.us/img849/8167/img1609m.jpg

OK, i solved the problem. The guy who sold the flex cable sent me a older one as I described. This thing was fully responsible for the errors. Bought a new one and everything works fine now^^ So if you ever want to change your Flex cable take good care which one you buy (especially on ebay!)
Btw: The display and the digitizer are glued and IF you want to replace any of those two, do yourself the favor and buy the complete bundle !!! I made the mistake and tried to replace the digitizer and cracked the display. There is no way as far as I can say, that you can manage this.
Bye

Can u post the seller info? Im in the same situation w a different phone... Thanks

[Q] Replaced LCD twice, only backlight comes on... What to do, now!?

Hey Boys n Girls!
I made a mistake and bought off eBay a phone with a "not working LCD":
" This is a used HTC Desire Z smartphone. The item was dropped on water and immediately pulled out. The LCD screen doesn't work anymore as some cable inside is cracked. Everything works fine, touchscreen, menu and the device boots fine, you can hear the sound etc but no image. Anyone can fix this if you have an LCD spare for HTC Desire Z and the phone can be used and works fine, just the LCD needs replacing. Comes with original box, manuals and battery but no charger or data cable. I want to sell this fast so Happy Bidding!"
, also ordered already from two different seller LCD replacement screens neither of them worked. Backlight works on both but nothing else. Im quite puzzled what to do next...
Anyone got any idea?
Please let me know! THanks in advance!

Sounds like some cable is not working, rather than the two screens you've purchased! There is a guide somewhere here for all of that stuff. Best of luck mate!

If you could kindly link that guide, it would be very much appreciated! Thanks!

try searching for ribbon cable. You should prob just take it to a cell phone store. Phone geeks in San Marcos did my repair for 70. I was texting gf while playing golf in pouring rain.

The flex ribbon cables are not that expensive. If you were comfortable replacing the screen, I would say you have the ability to replace the flex ribbon cable without a problem.

Im going to order it tonight and give an update as soon as I got the flex ribbon cable.... I assembled and disassembled so many times already soon will be able to do it blindfolded

Also while you have it apart clean the logic board with denatured or pure alcohol and a soft bristled brush. Let it dry completely! That way it won't corrode further from the water damage!

I will do that since it will probably take like 2 weeks to ship the flex ribbon from China Thanks Man!

No prob cheap insurance plus it could even since a current or future problem I do this work for people can you tell lol. Denatured is best otherwise I think 97 is as pure as you'll find. Most stores carry the latter.

Ps be gentle no need to go medieval on it

Replacing the Flex Ribbon Cable solved my problems.... Cheers Everyone!

[Q]Xperia Play with a messed up(grey) screen.

Now I have tried looking up this problem, though not many results as I'm not really sure what I would exactly describe the happening of my screen besides grey. So forgive me if there has been questions like this already answered.
"Right now my Xperia Play screen is messed up screen. It started today when sliding the gamepad would freeze the system. Now, the screen is making this grey screen (pictures below) and freezes. Sliding out the gamepad and sliding it in seems to unfreeze it for a few seconds sometimes. Though, mostly, there's this. Is there any way I can maybe completely wipe my phone and reinstall Android? I have already flashed it once. Or is this a hardware issue and will I have to go to AT&T to see if I'm able to get a replacement phone?"
Like I said, I've already flashed it once. Did a Factory Reset before hand, though I didn't expect it'd do much. So any other solutions?

Maybe you should head to Sony Centre or AT&T to ask whether what's wrong with it. A reminder, unroot your device and get back to stock if you have custom rom and rooted your Play.

i think when you slid the gamepad it removed the cable connected to the screen. what was it called can't remember

I'm getting this a lot. I think there is a ribbon cable loose somewhere. I'll look into taking it apart sometime.

Same problem as my phone. The slider flex cable is the problem according to 4 old threads I found. If you're still under warranty, send it in. Otherwise, you can buy a new cable on Ebay like I'm doing, for 11 bucks and install it yourself.
