Hello wdonaldgjr,

This set is very problematic. I would first suggest if you are going to repair this; get the schematic, forget checking fuses (that is not the problem). Look for CP150, CP140, CP114, and CP110, these capacitors are known to go bad and shut down the TV. Look and see if they are vented (gotten bloated and or puffy), even if they are not use a LCR meter to measure the capacitance of the capacitors, if they are under 20% of rated value, change them out. Also if the capacitors are not the problem, then check the flyback transformer, the horizontal output transistor. Yes this chassis is so jacked up that any thing in the HV path might be malfunctioning. Just remember check those caps first, and touch up any cold solder joints. If you feel that this is too much for you to do I advise that you take the TV to a qualified TV repair technician for servicing.

I hope the helps,

Thank you,

It sounds like your main fuse has blown or the power main relay has failed.Check the 40A and 30A fuses in junction block 2, and the power main relay in block 1. See here p10-11

Blown fuse caused by a shorted power supply. Relacing the power supply board should solve the issue in most cases. You can get a power supply board from www.tvrepairworld.com

#4 pin on towing plug does not have power even with key on. Can you tell me what fuse it may be? I have looked at all fuses and can't find one blown. Or, could this be a different problem?


Are sure that pin doesn't control the brake lights or blinker? In that case the on position of the ignition alone would not provide power. Have a second person engage the brakes and blinkers wile testing.Depending on the trailer type it could even be for reverse lights.

T.v is not getting any power.


Try unplugging the power for at least 10 minutes or more then plugging it back in.. If that doesn't work you may blown the transformer or fuse in the unit. If your unit doesn't have access panel for a fuse for the power supply it will need to be sent for service.
