Is this a bad CRT? 10BP4

This picture does contain picture information, however, it looks like a AGC
problem + Brightness way too high, and is displaying retrace lines.

But, since you replaced all the capacitors, as you stated, it can be anything
from the wrong part in the wrong spot, mistake in wiring, or something
else..... Along with this on the picture, is there quality loud sound? or
is it low, or does it have some noise mixed with it?

Use clues in pix, & Sound to guide you, + Check your work, + Check AGC.

Looks like sync is locked, Video is pretty weak - find the cause.

I would say the ion trap is fine for now, and the picture tube is fine too.

Addition:

When I say it looks like a AGC problem, I mean - If the set were not
completely re-caped and you know for sure the circuits were not
mistakenly changed to cause this loss of full signal at the point
it's lost now.....

Start by checking your work - especially signal path near and
after the detector circuit + Possibly include the AGC stuff.....
Don't discount possible bad tube, open IF Transformer, etc.

But first check your own work for mistakes....
