X640 blue display Hello, i received from a customer an X 640 phone with all blue display. It si full working but only blue display , i verified lcd and flex cable , they are ok (another x640 mainboard lights display ok) so the defect is on the mainboard, i tryed E2P full and custom reset, i tryed hiden contrast codes, even fullflash i made, but still same problem: blue display. Any idea, someone ... some schematics, or service manual... regards, doktortelecom |
i had one the same in work and could not fix it i had to replace the pba main . |
man, can you please tell me what PBA is? thanks mate, tonytony |
What I found so far is that PBA stands for 'Printed Board assembly'. Does that mean you replaced the mainboard? tonytony |
