Zenith Rear Projection Problems

[Darrell]

I am attempting to repair my Projection TV. Last night the screen went blank and the sound still works etc... But one issue I have is understanding all the different part numbers given for what looks to me as one board. 9-1674
I have seen 9-1674-01, 9-1674-03
I was fortunate to talk the guy out of the service manual when it was serviced under warranty.
I am not positive that I am missing the 115vsw from crx3412, but it is suspected. I am having trouble tracking the circuit with the board in so far. Can I disconnect the flyback transformer and still power up the set without worry of damaging anything else?
Possitive that something is fried from the smell.

I'm having the same problem with sound but no video as the other two guys, would it be the same part number for the power/sweep module for a Z50Z83D8 as posted before?

Same problem here on a z46z83d8, havent been able to track down a service manual as of yet so flying by the seat of my pants on this one.

I have the same problem. Channel sound, sound of channel changing, but no picture. What is the board # that I need to change for the Z46z83d8 or is it the same as the previously stated? Is it the power/sweep module? THANKS in advance!!
