Toshiba model 27a33 made in Nov 2003
Screen shows what appear to be retrace lines 2 inches in height at the very top of the screen. Lines appear on all inputs, but seem to disappear on some channels.

C406, C407 or C408 are likely candidates.

Looks like that did it! I can't narrow down for you which cap it was, because the position of the 3 caps in relation to each other and other components and heatsinks I found it easiest to remove all 3 caps at once and just replace all three (had them all in the spare parts bin anyway).
Thanks, you came through for me again. I appreciate you sharing whatever resources you seem to have at fingertips or in your head with me, and also your time.

I learned from you... Thanks for the idea. Sometimes overvoltage at grid can cause retrace to appear. Changing caps is one of the best additional...

You must work on some VERY OLD sets.
