RCA CRT TV Question
I will try to explain the following the best I can.
I have noticed that when I turn off my 1986 RCA TV there is always a thin blue line in about the Middle of The CRT. Also, sometimes next to it is a small bluish-green mark. They fade away with time after the CRT cools down. I was told this is normal is it and if so what do you call this phenomenon? Also, when I turn the lights out in the room and shut my TV off I get the folllowing. A flash of light and also some little dots here and there on the CRT. I noticed one of the dots/marks flashed a little like a small line or small flame. Also, I have noticed when the room is dark and you look at the CRT awhile after it has been shut off there is like this appearance of white cloud visible around the bottom or middle center of CRT. It's actually around the area I described with the blue mark. After time passes this goes away and the CRT becomes totally dark. Also, why can the CRT appear with lightness even though it hasn't been on all evening and you just turn your lights off in the room for the night and this brightness on the CRT appears for a short time? Do CRT's sense room light even when they aren't in use? One last question. Why when I sometimes turn on my TV with my RCA Converter Box I have no sound? However, if you turn everything off and restart it after a few times then its good to go? |

Does any of the above situations described sound like a problem is developing or is it just normal for this type of TV from that Era? I just worry that someday it will go out.
