Macintosh Portable M5120 partial line on screen

Posted by: gurrag on 2018-05-08 04:39:49 Hello, i have this portable that i have been repairing/servicing over the past few months. (Have done a full recap of the board and rebuilt the battery) When i was about to consider the repair done this line appeared on the screen after a few hours of running Prince of Persia. From what i can gather from older threads this is an actual problem with the LCD itself and not anything on the system board ? Would this be possible to fix by disassembling the screen (removing the glass etc) and cleaning the rubber/carbon contacts that i have read about in the same old threads ? Or is there something else i can do to repair it other then replacing the whole LCD ? I noticed a few electrolytic capacitors on the backside of the LCD panel - but since the screen seems to be working fine other than this partial line i guess those are not in need of replacing ? Overall the computer has been working fine since the recap, only the occasional hiccup which seemed to go away after charging the battery up to a higher voltage. Regards.
