Black screen, hearing a click noise about every 15 seconds, power light is on. Not responding to remote. Will not turn off (click noise about every 15 seconds from P/S) have to unplug to power off.
Other symptoms: Sometimes when you turn off TV it would come back on after 30 seconds. Before the TV went black, things started to act weird. Had to go in and clear memory and running apps. Then started to get a malicious process pop up notifications.
Took back cover off and used multimeter.

Leaning toward a bad main board, but have not checked the transistors or diodes on the P/S. Checked fuse on P/S good. Don't want to buy two items.

Leaning toward a bad main board, but have not checked the transistors or diodes on the P/S. Does anyone know what I should be reading for an ohms measurement on the transistors? The fuse on P/S was good.
