Panasonic dead set
Hello all: I am working on a model# CT32SX31E
When you press the power button the relay clicks, and nothing! VDC at collector of horizontal output is 139 volts Found a 0.1 uf electrolytic cap near IC101 reading an ESR and a 22uf electolytic cap reading ESR above normal. I neglected to get those location numbers, anyway the set was blowing the main fuse before I replaced them. Now the fuse is OK and I have a B+ of 139 vdc at the collector of HOT I still have a dead set. Is IC101 a common failure on this set? Any suggestions would be greatly appreciated. Thanks Dave |
