hi everyone, I am new member here, has been enjoyed crt projector for a few years, I had a sony vph1042q for the past few years, it casts me nice movies.

not long ago, a friend of mine gave me his zenith pro900 as a gift for me as i moved to a new house. this projector has been sitting doing nothing in his movie room for the past 3 years. unfortunately, when i tested it, it always shows "no input signal" on the screen, no matter i set it up with s video from a dvd player or RGB input from a computer VGA out into 5 BNC input,iand then i swap it with my old sony vph1042q, it works fine. my friend told me it was absolutely fine for the very last time he set up with his computer. now I am really stucked.

could anyone please tell me is that me didn't set up properly or could it be possible has a fault somewhere on the signal input borad or the signal processor or ....... tubs are working perfectly fine, i can do focus and those checks, corss, dots alignment using the remote control with no problem.


cheers

Assuming you are selecting the correct input via the menus, then the RGB input board is most lilkely bad. I've had those fail before. I've got spares if you want one, figure on $175 incl air shipping for the whole RGB input board. Unbolt the old one, bolt the new one in place, reconverge.

Due to the distance it's not worth you sending yours up here for repair.

oppps, thanks for pointing that out. I wonder would it be some other problems are there, coz neither s video or RGB input are working, and the s video borad and RGB board are seperate, could both of them failed? or is it related to some other part of the machine?

I've repaired dozens of them, so I'm pretty sure it's the RGB board. The video and Svideo signals run through the RGB board, then to the tubes. Other than control signals, all of the video processing is done on the RGB board for all signals.
