ONE: First thing to do is a hard reset. Merely unplug the power cord for 4 hours, then power up again.

TWO: If the reset does not help, try disconnecting anything on input 2. For example, if you have a dvd player connected to that input, the tv may be sensing its presence and switch over to it. (Especially, if the device is left ON.)

THREE: It is possible the controller IC is defective and is wandering around (electronically speaking). In this case, the set would need to be seen by a tech who can get inside and test the circuitry that controls the function switching. Lugging a big set like this into a shop is not easy, but is will save you lots of money compared to having them come to your home.
Let me know if you need more....

Hope this may help;

What needs to happen to view picture? Screen is currently black.


Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement.

Do you have back light when turning on the TV? if you do then just replace the main board should resolve the problem. if you do not have back light, you will need to replace the inverter board(s) depending on your model. The inverter board(s) is located on the left side of the TV facing back of TV. you may have two inverter boards depending on your model. the other is located on the right side of the TV. Both mount vertically.
