I have a Hitachi colour tv which is 20+ years old, it is not a "warm
up" tv, it usually switches on immediately.

Just recently, when switching it on it has a very thin horizontal line,
the rest of the screen remaining black.

After leaving it on for about 10 minutes the whole picture immediately
reappears. Sound is unaffected.

Would anyone have any ideas as to what might be wrong...?

Apart from the line now burned into the screen?
