1981 19" RCA XL-100 CTC108C no brightness after CRT cleaning

That makes sense & good to know it's common for those issues to happen. I ran it for hours over the last couple days and it seems fine now. Man this thing can make a good picture. It's going to replace the 1975 Sears Sanyo 19" I've been using for the Nintendo. It works fine but just doesn't have the clarity this one does.

Zeno, I can see the jail bars if I pause the DVR on a dark screen between commercials, so it wasn't my camera. I'm not worried about it but just curious what the fix would be, if it's an easy fix I'll do it just for experience sake. It doesn't have that blue tint in person, it's the camera this time.

OK remember this one. Its common to all brands.
The 3 color outputs are supplied with apx 200V. There is an electrolytic
off it. Usually 4.7 or 10 mfd @350V. On your set IIRC there is a big can
along the front of the chassis. It has two sections. One abt 800mfd
the other is the one you want. Just cut the wire off the 10mfd section
& install a new one to the wire. The 800mfd stays in. RCA got about
$20 for the cap so thats how we did it.
Symptoms are any of following.
Jail bars
Retrace lines
Pix dark at left & gets brighter to the right
Too bright
Streaking / bad CRT look
Pix is just not right
