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.

In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should trouble shoot. Contact any service technician. The circuit will differ with models and versions.

TV has red light but no picture. It appears to not power on.


It probably got zapped with power. Regardless of how it broke, the first place to start is the main power supply board. Some people repair the caps, which without looking more in depth at some of the troubleshooting forums, I couldn't tell you which one is most often the culprit. It looks like the power supply boards are going for about $25 on ebay, and I would feel pretty confident replacing that at that price.
If that does not fix it, something on the main board could be "crowbarring", or sapping power from power supply from where it is needed to boot up, however, that would only be a secondary test to making sure our power supply is a good one.

Have sound but no picture


The main problem can be the two back light inverter boards, or the main power supply problem. Look at the power supply for 24vdc feeding the inverter board first, it can also be cuased by bad main logic board not seding the signal to turn on the back lights.
