l have this LG flatron television, which AV just stopped working. The channels TV aspect is showing, but when changed to Video/DSTV, it is not showing.

I feel the AV panel is not working or experts, what could be the cause?

l had to do this because, I once had a gory experience with a repairer, so I want to appear to them prepared. Someone even suggested I reomve the panel and take it to the market and purchase the exact copy to replace it.

Experts, please help me with your suggestionns and possibly, cost of it.

Let me try and see if I can upload the pictures.
