The one on the remote or the one one the HDTV?
If it's the remote, you try new batteries.
I bought a Sony Bravia 46" TV recently. When I switch it on, the sound comes but no picture. I have to click power button ON&OFF many times to make the picture come. If I am lucky, picture comes in 3 attempts or else it sometimes take around 5 mins to show picture. Why is it happening? or is it with all the big screen TV's.How can it be fixed?
