We have a Epson Powerlite 77c Projector and the lamp light will not come on. The Projector powers up and when the green light comes on the direction say to push the menu button to reset the lamp but it never comes on instead the projector will then shut off automatically. We have replaced the lamp 2 times thinking it was that. Just bought a new lamp (bulb) and installed it. Please help us figure out what might be wrong.

Test the power to the ballast with a voltmeter. The ballast can go bad. If it tests bad, then replace it. If it test good, use an analog meter and test the resistors and capacitors to make sure they haven't been overheated.

I have hooked my Epson 77c to cable in the following method. Cable directly into old vcr, vcr cabled into tv, RGB cable from vcr out to Epson 77c video input. The issue is that I can view only channel 3 on...


VCRs typically do not have RGB outputs. If you are using the VCR as a tuner for your projector, then be sure you have selected the VCR/TV button to VCR then your VCR will be the tuner. If you have it set to TV then the signal is passed through the VCR by your coax to the TV and the TV is the tuner but the VCR is now only outputting Channel 3.
