This sounds like a bad connection or a bad capacitor in the 220 volt source that supplies the voltage for the CRT boards. You will need to get a schematic and trace out this voltage from the PM board to the CRT driver boards when the set acts up. it could even be a connection on one of the plugs from the PM board to the CRT boards. Sorry but not a real easy repair. Might take some time to trace unless a component is failing. Good Luck
yes......you can rplace the convergence ic's on convergence module......these are the big stk type ic's and also the low ohm resistors. These are 3.9 to 6.8 ohm half watt on the yoke return circuit. Let me know how you fare......regards. meder's tv
its in high voltage shutdown. if ya wanna cheat? it'll take a dimmer type switch to cut the voltage in half. slowly till u can turn it on. then full voltage. if it is in high voltage shutdown you then need a technicians eye 2 see the symptom thats causing the problem. remember the shutdown is caused thru a saftey mechnism, and don't burn the house down. my 1000 mile away diagnosis says your voltage regulator or horizontal is out. most problems are power supply related, thus the voltage reg. is bad. if you use a higher current dimmer switch ...its a cheater tool that technicians can use, so be carful. keep an eye on all cords...heat should not be present in any appliance , etc. thats the wire to the wall.
yes it can the cost is $350 sumwut dollars ,i got my tv for $54 and thats wut was wrong with it ,the board that is connected to your power cord is wut needs to be replaced sears can do the job but the labor is $200
