Sounds like you may need a new main board.

press up arrow then down arrow or left arrow then right should fix the problem iv had my tv do this twice and is how I fixed it but took me a while to find the fix both times so posting this here because this is the first result in my searches so hopefully if it happens to me again I can remind my self by helping everyone else

check the main power switch of the TV, then also check the control buttons on the front panel of the TV maybe one of the button s on the front panel is press (normally close state), or maybe the buttons is defective (maybe the menu button)

Bad Capaciotrs on the Power Supply Board can do this ,they will be vented or swollen on Top.

Hi,
Required power supply board is available in shopjimmy.com

If dead then its your power supply bad, if you have led lights and no picture then it could be inverter board.

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.

I purchased a sylvanis lcd tv and it won't work with my comcast cable remote...I can't turn it on or off with it or turn up or down the volume. i've called my cable company 3 times and they can't seem to help me. Can you help?
