your set is in the SAP mode go into the cutomer settings and locat the sound setting and turn it to stereo

you have to make sure voltage is getting to the Power supply board, if you know how to check for the 110-120v ac at the board and that there is no line fuse in between. If you are getting power at board then I would make sure the PS are good. You also can check to see if you have voltages going to other boards, Inverter boards go bad in this set alot, but you should still have logo light up white or amber, To get it right you must check voltages, carefully.

If it came with the TV, then there might be a problem. First check if you have the batteries in the right position, we all make small mistakes. If it doesnt work then there might be a problem with the remote, shake it kinda so you can hear if anythings broken. If it doesnt work return it within your time period and pick up another, because it could also be the TV IR. ;)

Press MENU on the remote control, select the default language and press MENU again. Select the energy-saving HOME mode on the next screen, and if you are using a set-top cable or satellite box with your TV, press the LAST button on the remote.

Press MENU to exit and start watching TV.

It can be power supply, T-CON board, main board, backlight inverter board.
First, look at the screen in darkened room to see if you can see any slight glow from the screen, if it does, then the problem can be the T-CON (not getting the 12vdc) or the main logic board not feeding the signals to the T-CON board. if not, next place to check will be the power supply module, make sure it has 24vdc which is required by the backlight inverter to work, the reason for not having 24vdc can be from bad DC filter caps (leaking/bulging top, high ESR) or short circuits in the inverter board which will cause the 24vdc supply to go into shutdown mode, so you may have to disconnect the power cable that feed the inverter board to see if the 24vdc will work without the inverter board hookup, you will need to apply about 3~4 amp of load to the 24vdc to make sure it can handle that. There are fuses on the backlight inverter boards also. So there is some troubleshooting you will have to do to find out the causes of the problem you are having.
