Open the back cover and check the fuses on Y Sus Board and X Sus Board. If you can find a blown fuse, just replace that board and your problem will be fixed.

The Can shaped little device will have a domed or puffed up top on it the value is printed on the side you can , or have someone replace the cap and you should be all set

This is a very common problem. The power supply board has failed and needs to be replaced. You can call 1-800-samsung to find out if this problem will be covered under a warranty and the nearest service center. I replaced at least 150 power supplies last year.

Try with that...
Sound but no picture.
Master or Slave inverter is defective.
It can be that the driver IC is defective or MOSF
inverter transformers, or 470uF 35V C
Replace driver IC BD9897FS or MOSFET's.
