Sounds like back - light problem. 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. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Hello Alfredo. turn on the tv and the DVD player. Use the tv remote and push the input key. When you do that you will see a list of choices. One of them is DVD. Click on it. That said, if that doesn't give you a picture from the dvd, go down through the list one item at a time and you will find it. Joe

Need remote codes for Supersonic tv model SC-1331


Supersonic doesn't use universal remote codes for most of their line...you can try 0096 and a few other listed on the universal remotes, but they don't work on most of the Supersonic lineup. If you have a working remote, you can buy a universal remote that has the "learn" function and you can "teach" it. Best solution: buy a new remote from Supersonic.
