HI Rahim,

It is not easy to cancel such protection if there is no schematic. Even with schematic one has to do some test or research to cancal and this will take time.

Hello Jestine,

I was repairing a dead TV set and found out that the HOT transistor was shorted. I replaced it and also replace the snubber capacitor. When i turned it ON it just worked for about 5 minutes then the HOT get shorted again. I suspected the FBT, i removed it from the board and brought it to the nearest shop for testing but the result was the FBT is good. So I soldered it back to the board. Tried replacing all filter capacitors sorrounding the HOT transistor but when i turned ON the set, again the HOT get shorted after a couple of minutes.

Can you help me in fixing this trouble? what are the other causes of this failure?

thanks in advance!
