RCA 36V430T Chassis ITC008HYN turns on and off repeatedly.
howdy, I have this monster RCA that is possessed. It will turn on and
then at random intervals will shut down and power back up. I have touched up any solder connections that looked cold, and verified the front panel switches are not shorted. I still have the problem. Any and all help is greatly appreciated. thanks, Gary |

You might just change the tact switches anyway if it is not a mechanical problem like this. These sets have lots of problems with intermittent operation due to bad switches. They need not measure a short. Leonard |

Leonard, Thanks for the tip. I have checked all of the switches for shorts, all read open unless they are activated. i am testing with the button panel out of the set so no buttons are are falsely activated. I read somewhere that it could be the power IC but I do not yet have a service manual to locate it. Leonard Caillouet wrote: "Gary L.

Leonard, I did not catch that the switches may not be shorted to cause
the problem. I have removed all of the tact switches from the panel and am still getting power up & power down over and over ...... I believe that eliminates the tact switches, do you have any other suggestions or feel that the tact switch cb is faulty?? the set does not stay powered up long enough to develop any rastor but does seem to generate hv (not measured but get alot of static on th pt). Any and all help is GREATLY appreciated Gary L. Woodruff wrote: Leonard, Thanks for the tip.
