Feint Screen issue on laptop
Posted on 2015-01-12
I have a issue on a Sony Vaio laptop SVF1521A1EW
The screen was damaged and replaced but shows as black screen. shining a torch onto screen shows that screen is working. Normally I would suspect backlight or rectifier but as far as I can tell there is neither on the laptop as the screen is LED.
The existing screen was CHIMEI N156BGE-L41 Rev C1, so suspecting an incorrect screen had been fitted I bought a brand new one. This shows the same issue, black screen but shining a torch shows the windows desktop.
The only thing I can think of now is that either the contacts on the screen cable have got dirty or the screen cable is faulty.
Ive never seen a faulty graphics chip that shows a feint screen. Normally its just dead so I dont think its that, unless anyone else had experienced a faulty graphics chip causing this issue?
Anyone got any idea's?
Thanks in advance
