Hi there!
I got this TV initially not turning on and flashing standby LED. Mosfet q9101 was found defective and have been replaced. After that TV normally switched on and was fully functional for about two hours, then switched off with the same flashing LED. The power supply board BN44-00458A was checked again, but no damaged elements were found. TV switched on again normally, worked again for two hours. The temperature of q9101 was not more than 40C all the time. Then it switched off again, the measured temperature of q9101 was 86C, and capacitor C9110 was 74C. Q9101 was damaged as well as Q9102. The type of q9102 can't be read due to the damaged surface, the schematics for this MPS is not available....
Any suggestions?
Thanks in advance!
