Screen burn

[94Blue]

So I have pulled both the cassette screen and the AC screen and they both had a little black burn spot on the screen. Is this normal or should I be doing something?

They're all like that. It's completely normal - the stereo head display also has it, as do most displays of that type in other applications.

And since I couldn't stop thinking about it, I found this lol https://electronics.stackexchange.c...t-is-this-suspicious-stain-under-a-vfds-glass
