This is a common problem on Sylvania Flat Screen TVs (I have seen a lot of TV with this same problem), It is usually caused by a failure on the Power Board.
A new power board will cost about $150 - $190 USD. If you have experience on electronics repair and want to fix it by yourself, you can get the board through ebay or any online store.
A TV technician may charge about $280 - $ 400 to fix this issue (includin parts).
Read the user manual for warranty information. If the TV still under warranty, contact the manufacturer for assistance on repairs.
