25 inch sanyo tv


If the horizontal lines going through the picture are fine white lines, then I would suspect the picture tube as having a heater to cathode short or some other problem. Since some sets have had a 3 year warranty on the picture tube, you may be lucky unless the labor to replace the tube is more than the set is worth. Sanyo is usually not a good name in consumer electronics anymore, so if you're looking for a replacement I would look elsewhere.

After a household power blips during bad weather, we have horizontal lines ....


Unfortunately there isn't any way to repair your tv as the magnet has distorted the tube that is in the tv and with CRT becoming obsolete the repair is likely to be very costly so probably your chaepest option is to buy a new tv .

White horizontal, zig-zagging lines


It sounds to me like you're describing the re-trace of the unit. It is repairable, and more so the sooner you get it to the repair facility.

Picture deterioration


Your whole problem my freind is dryed up capacitors. You should go, if you have the technical ability to replace these capacitors, to http://servicemanuals.net, download the schematic diagram, and start replacing the waveshaper capacitors in the vertical drive circuit.
