Hello all,
I'm trying to solve a few problems with my Sony console TV, and would appreciate any guidance. I do have the Sony service manual for this set.
When I purchased this TV I noticed a pincushion issue. Upon some troubleshooting, I noticed a leaked capacitor in the pincushion circuit. I replaced the cap and adjusted the pincushion pots and this issue is mostly resolved. I still have a slight bowing outward in the upper half of the screen. Any ideas on what else I can look at for this?

After new cap and adjustment:

Now I have noticed an additional two problems.
First problem is on a completely black screen, the left half of the CRT is brighter than the right half. There are also a few faint vertical lines on the left half of the screen. Unfortunately I can't find the picture I took of this.
The second problem is that the Red and the Blue seem to be bleeding? I don't see any divisions on the color bars. The white is perfect, and the green has most of the divisions.
