HAVE A TOSHIBA CX32C81 THAT WHEN POWERED ON CLICKS AND HAS HV BUT NO SOUND OR PICTURE ON SCREEN, IT WAS WORKING GREAT THEN ONE TIME THE SOUND CAME ON BUT NO PICTURE TURNED OFF AND BACK ON AND WORKED FINE FOR A FEW DAYS and now just a click and no sound? Help Please!!!

You hv bad capacetor on power board. Just open back of your tv and you will see couple capcetor swelen. They are only couple of dollar each. You just need to know to soder them

The deflection board in failing, eventually it will not come on at all, disconnecting power is only reseting the HV shutdown protection circuit which is the reason your set if failing. Have a technician replace the Horizonal Output Transistor and the flyback transformer.

Please comment if you need futher assitance.

Is this set a RCA ? You may want to double check the seating of the Anode Lead from the HV Transformer to the HV Slitter, If pulled out
a little arching will occur with-in the Bock and cause premature failure if not corrected. Also make sure that all ground connctions are made from the CRTS to the HV Block if there are any.
Hope this Helps,

that relay is supposed to engage power to the tv boards that control the screen.
you will have to take it to a oualified service center , because they have access to parts that are needed for repair

You need a new HV transformer. Usually you can just buy the transformer itself. It's a little black tower on the backside of the tv. If it's not that, it's the convergence ic's. There's two of them, given it's a toshiba, the part number is more than likely stk392-110.

HV Power supply

Sometimes when the screen gets cleaned some cleaning fluid leaks down the front of the crt and scuzzes up the front control buttons

Bad HV transformer = RCA part # 271996.......................T.

fermin,
Please log on to Toshiba rear projection Television>>>>>>>>>

turbo5150,
The exact same problem with ? = Make & Model,please....T.

It sounds like the Power transistor that drives the High Voltage Transformer shorted out. The rapid clicking sound you are hearing when pressing the power button now is that of the power supply starting to come up, detecting a short circuit and shutting back off again, preventing further damage. It is likely that the HV Transformer is shorted as well which usually causes the Output transistor to fail. Since the set is only 2 1/2 years old, it is probably worthwhile getting it to a repair shop as long as you have been very satisfied with the picture quality up to this point. If the picture size was larger than you needed, you might consider going down to a 37" LCD HDTV set. Toshiba is tops in this category IMHO.
