| 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,
