SONY KDL-42W805A TV: No Picture, Sound Present, Channel Switching, Unresponsive Commands

Hello Forum Members,
I have a SONY KDL-42W805A TV set and, unfortunately, the picture is off, the background is black. I only perceive the sound, after the sound I know that the channels are switching. In addition, there are no functional commands on the monitor, nothing is displayed, such as channel change, or other symbols from the remote control, etc.
Has anyone encountered such a situation?

I suspect that only on the site? * or someone from the forum will find "cure" for damage in
