SOURCE: power button is green - no blinks / no picture / no sound
Unplug it from the wall, wait 2 minutes and plug it back in. if problem still exists, its probably the main pcb.

unplug from the wall and wait a whole day then plug bak
SOURCE: Apex Digital TV Model: 1919. Worked fine for a
Power supply issues or shorted horizontal output transistor. Probably not worth having repaired unless you DIY....
SOURCE: line accross top of the screen with flashing black and white boxes
Go to menu and settings and look for OVERSCAN and set this to on and hey presto no more white lines no matter what ratio your in.
SOURCE: Red power light and buzzing sound with red lamp light.
If the lamp does not light at all, it is probably a bad lamp. The buzzing may be the ballast trying to start the lamp or a problem with the power supply. Check the lamp and see if the arc tube is broken. If its a new lamp, you should be under warranty. I have the manual if you want to go to me site at allprojectorlamps.com. Just send you email to me attention Bulb Guy
