Sony India — Projection tv

Address:

Udaipur, Rajasthan, 313001

I had purchased a sony projection tv 8 years ago. a few days ago it has stopped working. when i switch it on, the sound can be heard for a few minutes and than it goes silent. but the picture is totally gone.
once in a while, when i switch it on, the picture and sound are working. But after switching it off, next time when i switch it on, it does not work.
please resolve at the earliest.
i have tried to contact your local dealer and explained the problem. But he is not responding or taking any action.
