Recently my computer screen started to flash and now has a continue green screen (haze & occasionally it will revert back to normal for 5 or so minutes). Do you know what could be causing this problem. Also at the same time my battery died and now only works when it is plugged in (shows a X in the battery icon). Would appreciate your suggestions and help. Regards Aaron Update (11/10/2016) MODEL is a MacBook Unibody Model A1278

I can think of a few reasons, and I’ll list them in order: Loose display signal connector: unplug and replug the connectorDead battery playing with voltages: replace the battery with an iFixit replacement batteryDead graphics adapter: replace the logic board
