I have been doing electronics for the last 30 years. I have not seen
where the smps had caused his type of problem Unless there was something I have missed reading in his post. I still would say we need to know what was wrong with this flyback first before we start saying other things worng with his set. We need to know why he had put goop on it. This maybe his only cause of his problem at this point. |

It may have nothing to do with his problem, but any tech who works on the
ctc169 chassis should know that these caps are a problem waiting to happen and if they test high in ESR should be changed. It would be poor service not to give the set a thorough evaluation before suggesting a fix. If he does not have the equipment to test them, he should at least change the two caps on the smps controller IC, which are the source of more failures on these sets than any other. Some shops don't look for potential problems waiting to happen. We feel that a complete estimate includes checking the stuff that tend to cause other problems. Leonard "tvguy" wrote in message . ..

So as for discharging dangerous caps, do I need to just short them with a 1MW resistor? Where is the HOT located? Where do you find a 1 Million Watt resistor in the first place? ;-) -- Service to my country? Been there, Done that, and I've got my DD214 to prove it. Member of DAV #85. Michael A.
