Does displaying no signal on a CRT cause wear?

post #1 of 2
Thread Starter 
My CRT TV has more noticeable overscan when the set is first turned on. After it has warmed up for 15-30 minutes, it is back to a normal level. Because of this, I often leave my TV on even if I am not planning on using it for anywhere up to an hour. There is no signal on the input, so it is just the black screen.

I assume that the TV displaying no signal will not cause any wear on the tube. Is this correct? Is there some other harm I am doing to the set by leaving it on in this manner?

Well, there should be little to no wear on the phosphors. OTOH thermionic emission is still going on in the guns, whether electrons are being directed toward the phosphors or not.

I wouldn't worry about it because it sounds like you are going to have other problems first.
