The picture disappearing is a sure sign that a tube is wearing out, and it will need to be replaced.

The problem may usually be seen more after startup and then get better, but it may persist throughout your viewing as well.

One temporary fix would be to go into the user controls and adjust the contrast (or screen control) and brightness down a bit, and the problem may subside for a short time.

Let me know if that works for you.
