Screen issue: fat vertical lines
Hi! i just bought this iMac 17" because i want to repair it
The thing is that the lines are too fat, so maybe not a logic board problem but a screen one?
I hope that i just should buy a new motherboard :(
What do you think? I have been looking for information on the internet, but my english level isn't as good as i want so nothing relevant found...
I would suggest you do this first before taking any further steps:
1. Plug in known tested working monitor and confirm you have video. Make sure you test the monitor on another computer and it definitely works or you might spend more than you have to.
2. Determine what to replace first:
- If you have video on an external monitor, replace the LCD screen on the unit first.
- If you do not have video on an external monitor, replace the system board.
You may have to replace both. If replacing both of these items does not fix the problem, you may have to put it back on ebay as parts along with the new LCD and system board and just recoup your losses.
