Do you have any clue if this is a really burn or something that happen because any chassis issue? Did you had similar issue with another tubes to know possible causes? Chassis is PD1843.
It seems not a burning but i have no idea if that problem could fixable or not, if comes from chasis, if is a common problem tube, etc

Thanks for help.

do you get same result with a different video source as it is not a fault I have seen before, I could understand if it was a section of the horizontal but never exactly half a screen darker on the vertical before
