Question: iMac still getting black screen HELP!!!
Apple iMacå27” i7 2011 3.4 Ghz
Only 3 led lights will come on!
I put in new power supply!
I put in new backlight board!
I bought another monitor!
I got new 3 new ribbons.
Computer starts with external monitor works fine.
I while ago I put in monitor ribbon that has a pin missing it went black after a few minutes.
Since then the screen will not light up.
I tried everything I can think of…
Have you ever run into this or heard of this problem.
So I’m thinking it the old ribbon did something to the motherboard.
I took out motherboard it looks good no bulging capacitors or leaks but i did notice a little white residue on front of motherboard under 2 capacitors.
I’’m trying to fix this myself never done this before.
I have been working on it for months learning as I go…..
I am really getting depressed over this.
I don’t have anymore money I live on fixed income.
This is the only computer I have.
I appreciate your interest I am not a technician DYI
In fact I’m using it with my tv monitor now!
