Hello there Mr. Green

I have a pretty big problem with samsung (chassis S63A).
The original tranzistor J6920 (HC401) has been replaced with 2SC 5446 (2 times) and with 2SC 3997 (one time). Every time the tranzistor is replaced the TV starts and works for about 10 seconds and then dies again Sad
Everything else seems fine!
Please help!! Wink
