It is most likely a faulty capacitor on the convergance or other system board that will need to be found with capacitor tester. It will need to be replaced.

Testimonial: "thanks for ur help really helpful and quick reply thanks again "
SOURCE: sound but no picture
Most likely you have an inverter problem. The inverter powers the backlights so that the picture can be seen. You can try holding a flashlight close to the front of the screen in a dark room and if you can see any trace of a picture, the backlights are not lit. This can be a pretty hot circuit to work with. Have a shop check it out for you. Thanks for using fixya.

Problem is in either power supply or - my bet - the Y-Sustain board.
The Y-Sustain is a relatively large board out of which go connections to the side of the display; it's therefore closer to either the left or the right side of the display, has at least one rather large heat sink on it and fat power cables connecting it to the main power supply.
Often there are fuses on that board - one or more. Check those.
if they are blown you can try to replace them, but expect them to blow again - usually the whole board needs to be replaced.
often that *needs* to be done in a service center as there are some adjustments to be made after replacement; don't know about this particular TV model.
