Model P46770CKLG1 CTC169PAAS CL4413. This set looks like one of the first 169's..I'm embarrassed to post a question on this set being so familiar..but I've checked all I can think of. At customer's house, found HV arcing at splitter. I assumed bad splitter..so replaced. Then, set would fire three times, remove anode lead and fires once and shuts down. Replaced flyback, same thing. Replaced HOT, regulated supply (U4101, Q4101, all caps(4) checked all resistors and replace 3v zener(measures -1.5 on anode and 1.5 on cathode in run) HV comes up to about 35k. HOT coll is 147 in standby, drops to 143 in run. B+ at fly about the same. Q4101 C=174 in stand by, 157 in run. Disconnecting the HV board(on the HOT heat sink) makes no difference. With the anode connected to the HV block, some times the set tried to start three or four times, other times only once.(Disconnected, only once) First guess was another bad fly, but both actually ring good on my Sencore VA48. I started back tracking in case I got bad parts for regulated circuit, but I get the same symptoms. All parts are OEM except U4101(which I now have the original part in unit). I have the Fix finder for this chassis and went down through every thing. Has anyone seen these symptoms? Thank you
