Our Audiovox 12 volt television shows a white vertical line in the center of the screen when you turn it on. The picture would show and then get to a narrow vertical line. Now there is no picture at all except the white vertical line.

Re: Audiovox AVT 1598
The vertical output IC or the vertical circuit is whats at fault. its all solid state and im sorry to tell ya that its not a user replaceable part. This set is probably not worth the repair it would take to get this set working again but please if you like ask a ;ocal repair shop what they thought about this problem.. Good Luck and please dont forget to rate this thread

Visually check elec.capasitors, then measure output voltages of power supply. First of all, try to find service manual with schematic diagram in Internet. Vertical or horizontal scan seems to be fault.
keep tv off.
it will only get wors
if sumon dosent work on it soon
the problem you are having in the vertical section of the tv
hav a repairman resolider all conection on the vertical IC and check the serounding componets for falts.
PS the repair takes me about 15 min.
The problem you are having is a vertical deflection problem. The screen is being compressed to a thin white line. It's probably a defective vertical output module or transistor. This part is not too expensive. Less likely would be a vertical deflection coil, which would be more expensive because its usually glued to the picture tube and harder to replace. You'll need to take your set to service center to have it serviced.
Please let me know if I can be of further assistance to you.
That model has a history of bad solder connections in various circuits. I would not be surprised if that is the case with the color circuitry. You may get the color to come and go by slapping the sides of the TV or lifting one corner about 1/2 inch and dropping it. If it does, it is a bad connection and possibly fixable. If no change is noted, it could be a bad semiconductor or capacitor, etc., causing the symptoms. For that size set, it would probably be cheaper to replace with a different brand. Toshiba has a nice 14" model IMO.
sounds like you have a vertical sweep problem. Where the fault lies cpuld be the vertical output IC the verticle b+ feed, could be the capacitors in the vertical circuit?? Your gonna need to troubleshoot thr vrtical circuit if your not a tech thin my advise is to take the set to a pro for sn est. Good Luck
