Re: 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.

You will have to inspect the pins of the vertical IC. They may need resoldered. And you may have to replace some of the capacitors in the immediate area of this IC. If you still have a vertical problem you may have to replace the vertical IC.And please check the diodes near this IC, rare but occasionally they will short out.
this sounds like a verticle foldover problem . This could be as simple as a defective wave shapper capacitor or could be the main vert. sweep IC also. All these parts are soldered in so if you have no experience with this stuff please seek profesional assistance with this repair Good Luck
