My exact same problem turned out to be the cable box not the TV. Try unplugging cable box for 5 minutes then power up! Solved my problem!

Theres no start-up signal being encoded, this means the interface board has an offset capacitive value. You need to test and measure the capacitors and npn/pnp transistors, along finding some open diodes too on the main board (interface). You have to test the capacitors under their operating voltage also to see at which point their breaking down. The problem is a 'load' condition on the main board. You can repair the board if your savy and you have test equipment or you can just replace the board. If you want to replace it e-mail me and I'll help you out....

Recommend opening it up and looking at the power board and see if there are any visible Bulged or leaking capacitors.
Bad caps are a major source of computer and LCD no post problems.
If you find em, then just find replacements with the same uF and voltage and solder them out/in.

SOURCE: I have a RCA L32HD31YX12.
Thanks in advance for choosing Fixya for assistance.
I would like to make a clarification request , before I present my possible solution to
Does it happen on all TV inputs ? or just on the tuner?
Have you tried connecting the TV audio out to your AV Receiver or similar just
for initial troubleshooting?
If it happens to produce sound on your AV receiver , then Congrats...
you have just troubleshooted a large percentage on electronic circuits
inside the TV ( even without opening it up ).
I can post further , while I await for your answer , to resolve the problem
you are having and post if you can further DIY ( inside the unit )
