Check its horizontal output section circuit for any loose solder terminals. Resolder all suspected solder terminals by applying little more fresh solder. Replace the horizontal output transistor. If this transistor have some leak, it will overheat within minutes will shut down the picture.

Black screen with sound


Hi,
You Tv have problem with the backlight inverter board. This type of complaint can occur under two circumstances.
1.Faulty electrolytic capacitor in the power supply board
2. The back light inverter board.

If you have knowledge in electronics then check the power supply for any faulty or budged electrolytic capacitor. Have adde the picture of faulty electrolytic capacitor how it will look like. check the link. faulty capacitor .

If the are no such faulty electrolytic capacitor then you have to replace the back light inverter board. There is no repair possible with inverter board because its spares are rarely available.

You have didn't mention any model number of your tv. so its not possible to add the exact picture of the inverter board.

Ok
