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
