well this is my friends computer.. he said that the screen wasnt working so he got mad and cracked the lcd screen i replaced it and it still doesnt work
what im starting to think is that i might of not connected the screen all the way in because on the back of the screen it said that there was a lock wich im guessing was for the ribbon cable but i didnt find it
That would be my thought too. Does the computer still power up and sound like Windows is booting in the background? If it doesn't even power up, I would work on the computer first.
Most computer repair shops will give you a free quote on how much it would take to repair it. That would be the best decision I think..
Hope this helps.
