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)

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!
