Line left to right is vertical circuit problem and may be linked to audio problem if both are fed voltage from a common source---Not a do it yourself repair unless have experience with this kind of equipment.

SOURCE: Sanyo DS31590 31" TV vertical deflection

If the vertical is not defective or shorted there is a possiblity of bad solder connections on the vertical ic. If connections are good and has b+ voltage to the chip replace chip which is IC 501 LA7841 or LA7845 and change c511 (decimal point 1 film capacitor)

Replaced vertical IC ( la78041 ??>.. Or La78040 ). Look for born resistor beside IC. Replaced capacitor 100uf 35V too!!! Good luck !!

Tv has horizontal line in middle of screen,sanyo ds25390

hi if only a horizontal line across with no video anymore, you have bad either vertical ic or no dc supply b+( vertical ic ) or no output dc coming from the ic. if it is not totally a horizontal white line and you can see a video you must check leak or bulged capacitors at the vertical section near the vertical ic. hope this can help good luck.

Tv not working

this symptom, sometimes called the tube light effect, it is characterised by a bright thin horizontal line across the middle of the screen. this symptom is caused by a breakdown in the vertical deflection circuit. hence maybe the trouble maybe in the vertical oscillator, amplifier or output circuits. but if all i have said is not clear to you, better bring it to a qualified tv technician. good luck!
