I have a 60 inch Samsung TV (model UN60J6200AFXZA). The power board overheated and a capacitor/resistor on it popped like a firework and burned out. I ordered a new power board (part number BN44-00775A), installed it and the TV worked fine for 40 minutes. The picture started to flicker on and off and the TV wouldn’t turn off. The metal back cover of the TV was really hot, couldn’t touch it and there was the smell of an electrical fire starting. I unplugged it, let it cool and took the back off. The new power board looks fine, no capacitors or resistors blown/bulging and no evidence of charring. There seems to be very little info out there in diagnosing the problem I’m having, let alone fixing it. I’m at the point where I don’t know what to do. The TV is only 4 years old and I really don’t want to drop over $750 or more on a new set.
I don’t know what is wrong with the TV, it seems like it’s drawing too much electricity and overheating, don’t know what would cause it. Any help would be greatly appreciated.
EDIT 3/17/21:
I tried to turn on the TV again and still have the above issue with 2 added ones. Now the volume control doesn't work and when I turn off the TV, the screen stops receiving signal but the LEDs are still on. I have to physically unplug the TV for the LEDs to be off.
