Answers :

I think I came across to a similar situation, try resetting the RAM by pulling it out and inset it back properly. If it does not work, try replacing the RAM from a working Laptop and see. Normally after disassembling the laptop assembling it again the RAM does not sits down properly causing the no display or a faulty RAM either.
