Hey Carson,

Without seeing the set, it is hard to pin down the problem. But I would guess you have a problem with either the t-con board, t-con ribbon connection problem, or a failing LCD panel. Samsungs are known for premature panel failures. The problem is by that time you pay a diagnosis fee, parts and labor, you would be close to the price of a new set. If you are financially able to buy another set, I would do so and toss your old one on Craigslist. If you get $40 bucks for it take the money and run !!!

The problem is the LCD panel went bad, it can't be repaired, you have to replace it.

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. http://electronicshelponline.blogspot.com/ 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.

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
