Question about Samsung Televison & Video
Samsung 46 LCD, LN46c630k1fxza

Sounds like what my flatscreen did. What i found it to be when i removed the back is, capacitors had failed in the main board. Only spend 12 dollars on capacitors, hardest part was soldering them in.

Most likely the screen itself needs replacing, but hard to tell without full inspection.

You got sound meaning the power supply and mainboard have no problem at all. Look at the back, have you seen back light lit up?
If there is light, the problem may come from T-con board.
If there is no light so the inverter board has defective.

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.
