Question about InFocus ScreenPlay 7205 Multimedia Projector
I have an IN24 with 6 black vertical lines pulsating, what causes this?
Possibly a resolution issue (clock and phase). reset the settings to factory default. if that doesn't help, there might be a voltage or colorwheel issue. does the projector chirp? if so, it's the colorwheel. if not, there is a voltage/grounding issue. check to see if the plug has 3 prongs on it. if the round prong is broke off, replace the cord. if not, check the fans. if they all are working, you have a power supply problem that is not regulating the voltage properly. replace the power supply.
