If it was possible to establish that the TV was the cause of the malfunction, you should remember if power surges have occurred recently. After a thunderstorm, the power supply could be damaged, as it takes the brunt of the sudden changes in electricity. If this element burned out, it will have to be replaced with a new one. A power supply stabilizer will help protect devices from the consequences of such situations in the future.
