Why black screen, gradated screen when working and screen freeze?
I have been having issue of intermittent black screen on my iMac.
The screen worked for sometime then started showing gradated screen. The top section being lighter with the bottom being darker.
I replaced the LCD display thinking that would solve the problem, but it still has the gradated screen and it freezes up.
I opened it back up and checked connections and cleared out the dust on the fans.
Now, it's back to a black screen. I took a picture of the power source while I had the computer open because it looked odd.
If someone could tell me if they think the power source is bad or if maybe the inverter is causing the issues, I sure would appreciate it!
Es esta una buena pregunta?
