Thanks Mike for the advice. You guessed it right. Not a TV service person. But there is always a first time.

I know the fault may not be a major one and I have the feeling to be able to tackle it successfully. But I am stuck on the first step only.

The reason for my taking this up on my own is that there is nobody here who can do this work in this part of the country. Even if there is it could be a expensive now that people rarely service TVs.

I am relying a lot on this site for some moral and technical support.

Hope you will understand. Thanks again I will be careful.
