sounds like you have it set correctly..do you have any other sources than external,(such as audio out) ?If so that should solve your problem...does the system have any other connection outs, such as red white audio cables (LR audio )? You can use them as external when the optical is unplugged...if you get sound you either have a bad optical cord or the output for it is defective..good luck GOD BLESS

Caps can fail with no outward signs. It takes a special meter to test them. Your set may have a back light inverter that powers the back lights. When it fails, the picture cant be seen, but you have sound, to check this look for a picture on the screen using a flashlight

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 be troubles hooted. Contact any service technician. The circuit will differ with models and versions.

Hi, not sure if you have the same fault as i had, but our tv only had half the screen go off, after looking up on the internet i found a video for a fix, what you need to do is remove the back cover, there will be ribbons that go from the front screen to the main panel, i removed each one at a time and rubbed the contacts of the ribbon with a rubber on the end of a pencil, plugged them all back in and switched it on and it was now spot on, thats more than a year ago and its still working spot on, hope this helps

You can also replace the bad capacitors on the power supply board.

Sounds like the LCD Panel, if under warranty contact Samsung warranty for service. If out of warranty, watch it until you tire of it then replace the unit as the cost of a new panel is more than a new unit.
