HTC One X LCD Backlight Problem - Page 2 - GSM-Forum

Frepa_AL · 11-07-2012, 11:36

Dear Colleagues,
wish you all the best, meanwhile I like to discuss with you a strange problem regarding with a faulty HTC one X. It have problem on the middle of the touch pad. It does not respond on digits 1; 2; 3 during dial pad so it is impossible to dial up phone numbers that include these digits. Can somebody tell me if there is any solution in this case? The phone has good condition touch pad, there is not any scratches or dirties on the LCD. Any kind of help shall be much appreciated.
With best regards,
FrePa,

see picture in post #18, inductor #1, from phone, this coil identif. 220 = 22mH
coil-2 I can't finde discription.
But i find this coil in, Desire-S.

If you want replace a first time, both coils's DONT POWER ON your device!!!
Replace necessarily IC TPS65200.
If you replaced first time both coil and phone turn On, the chip burn.
I have two chips burned. unknowingly(((((

IMPORTANT!!!!!

If there is a problem with the backlight, be sure! Change and both coil and chip. Only then switch on the phone!

Unfortunately, I have the exact same problem. While looking on what is not working!

According to the datasheet, the backlight is a zener diode. As I understand it, it just gives the stabilization of current to the LEDs. There is a suspicion that it takes place. We must look for this sign. 90 percent chance that he interferes, live the light chain.

Hi,
I have a problem with newly replaced screen. Everything looks that works fine(touch, backlight...). But I have problem with colours. It is actually not black but kind of grey and all other colours look the same like the brightness(not backlight) was set to 100%. The screen should work with no problems like that because the guy from the gsm service told me he made many replacements with this screen and nothing happened like that.
I attached a sample to let you imagine what I am writing about.
Thanks for reply in advance.

Hello, I have an HTC One X model PJ83100 US version. The motherboard is different than what is shown in the photos in previous posts. The 220 coil appears to be a '100' and in a different location. The second coil and the IC are also not as shown in the pictures. Does anyone have experience fixing the backlight issue on the US models and can you get the parts from the US versions of the iPhones?
