Zenith Projection TV. Model#Z56Z83R	Can't Post

I recently aquired a tv that doesn't work. It's a projection screen and it only displays three colored bars at the top of the screen in an upside-down rainbow, but the sound still works. I can't find any service manuals or even owner's manauls. Got any suggestions?

If you are a technician,usually,it need to replace R3243(110K ohms)goes open.Also check Zener diode D4001 in Convergence board.(check this board too).If it is not solved the problem,check whole Convergence circuit.It probably needs to replace the ICs(STKs)in this board.
