A black line (about 2 inches wide) appears at the top of the screen with this amount of the picture looking like it is folded down translucently over the remaining picture. What's up?

Your TV has vertical fold problem. Just check all the electrolytic capacitors. On checking, most of them may look good. But on circuit, when energised, will show problems. So it is best to replace all of them once and check. Please check the electrolytic capacitor connected to the vertical power supply [usually comes from the secondary supply section of the Line Output Transformer], first, and replce it. It may be a 1500Mfd or 2200mfd. Check it first by replacing a new one. In most foldover cases, this service will solve the problem.

Lines at top of screen, about 4"

This is due to vertical deflecton problem, there is some capacitors that has gone bad and need replacing. It might just be one cap rated at 100uf 35 volts. This is called vertical foldover eventually the top will fold over or you will get a 4" black border on the top of the scrn.

Folddover at top of picture about an inch from top

Replace cap. 2465 and cap. 2561. That should take care of it unless the vertical transistors are bad or there are other bad caps.

Wide black area top of the screen.

More than likely it's not the crt. If the picture has "foldover" at the top of where the picture is currently, then more than likely there are bad caps. in the vertical scan circuit. If not, the vertical sizing probably just needs to be adjusted. You will have to get in to the service menu to do that.

Sounds like retrace lines. Leaky caps or worse can cause this.. Are you getting any vertical foldover at the top of the screen?

DS25390 Verticle foldover

If you have a picture but the top is folded over, your vertical IC is probably good and you need to replace the pump-up capacitor next to the IC. When the pump-up cap (typically a 47 or 100uF 35V cap) is open then the picture will have white lines and foldover at the top. The typical vertical output IC is the LA7838, but I am not familiar with exactly which output IC your set uses.
