Title:
Flickering jumping Horizontally after awhile also bootup colour issue
Text:
hi Recently my g5 20'' 22 Model A1076
has developed a flickering over the whole screen area and jumps, i noticed few months ago that the 3rd of the screen from the top had a noticeable lower luminosity/brightness [like milky greenish]
Q. Re these related or am i looking at a combination of issues,
I have using you tube information inspected the main boards psu logic and cables but couldn't see anything obvious. However i had to clean the fans from clogging fluff and dirt, there seem to be some improvement with the flickering but now its back again, the start-up colors are also naff as it is pink then gradually improves to white.
I have also reseated connectors as a backup.
does anyone have any ideas on this?
ta! chris
