Most likely, the problem is a defective Main Processor Board. This is the board with the antenna, RCA and HDMI plugs. You cant repair or replace component parts on this board, so dont even try. You must replace the complete board. The TV says Sylvania, but it is a bloody Funia TV. Several years ago this foreign company bought out broke-azzz Sylvania . They are still carrying the Sylvania name since Sylvania was a popular TV name in the 70s. Every electronic company in the USA is now owned by the Chinese, so call Funai and order the part from them. Dont be surprise if they dont have a clue what the heck you asking for. America and all electronics have gone to the puddles. Do you know why? GREED.

A job for the technician on this one. I have only worked on several flat screen before, on my last days as an electronic technicians. Half of the ones I worked on was the power supply inside ir the problem was like this. Instruction on how to fix them would require me to write many pages on electronic theory so, I am very sorry It is almost impossible for me to help you on that. Be carefull where you take that tv to. some shop can't fix those. You may have to search your local area for someone who specialize in flat sreen HDTV. Well I hope I have shed a little light on the problem. Thanx for posting the problem.
