Recently, my A3000UX has been displaying with a purple cast. If I leave everything turned off for some time (at least several hours) it looks all right for a while, before suddenly changing to that purple cast. Occasionally it changes from one mode to the other. I don't think the problem is with my 1960 monitor, because the behavior does not seem to be influenced by turning off the monitor, just the main computer.
I've tried taking the top off the case, but nothing looked suspicious to me. The problem still persists with the top off, so heat does not seem to be affecting the problem. Any suggestions?
