TV was purchased in Sept. of 1998. Problem is: picture has become a horizontal line in the middle of the screen that jumps around a little but refuses to become a picture. :) Sound is OK. The line appears when the set is turned on and as I said is not steady in the middle but bounces around. There is no flash of any form when the set is turned off. I hope I'm saying that right. What I mean to convey is that on and off appear to behave normally.

Bad vertical IC LA7841, just repaired one
My tv (ds25730) had a shorted output transistor replace, pulling in on right hand side of screen liking about 1/2 inch drom having a full screen.
Set has a bad vertical sweep IC. Also This Sanyo has a tendancy , when the IC blows out , to take the fusable resistor in the sweeo supply that feeds the vertical IC. This set should only be serviced by a trained technician because of ther high Voltage that lingers within. This repair should run you antwhere from 85.00 to 150 bucks. Good Luck
