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.

Vertical deflection

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.

Logik lt2974 small picture

the problem is in the verticle section, if you are a technician check a verticle IC and a capacitor of that stage. to allocate a verticle stage follow 4 cables coming down from deflection coils, two of these wires goes near transformer, this is horizotal and the other two goes near an IC this is verticle. positive idea.

Need an antenna block for a Sanyo DS25390

Was the block a cube about 1" ? You should be able to salvage one from an old tv. This block is used to isolate the antenna/cable from the "hot" chassis inside your tv. If you should find a used block ,make sure it does this. If you get one that gives you a direct connection to the chassis, your antenna/cable connector would give you a shock and probably burn out something in your tv when the cable is connected. Some of the Sanyo's have this connector made on to the tuner. If this is the case you'd have to either put a new coax connector in the tuner OR replace the tuner. Stargazer

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
