Question about ViewSonic A90f+ 19" CRT Monitor
No signal displayed at top of screen display keeps changing colors from red to green to blue to white to rainbow to black... nothing works, no buttons, no remote, no power button..
Try to check the RAM, video card, or processor maybe it is not properly inserted to the slot.
