Question about Audiovox AVT1498 TV

2 Answers

T.V. overheating in our conversion van

Our 13' Audiovox AVT-1498 looses it's picture after it is on for about 5-10 minutes. We get a gray strip through the middle of the screen, but the sound is fine. We are assuming something is overheating. It is $200-$300 to replace. We already bought 2 portable DVD players for our two young sons, but we can not connect the PS2 to those. We were also looking into satelite television, because we regularly have a 10 hour drive to Grandma's house. Was there a recall we do not know about? Can we just replace a less expensive part?

If you suspect overheating then try removing the back and clean out with a long, wooden handled artists brush. Make sure the children are not about and try it with the back off, but do not touch things inside. You may blow cold air if you see what is overheating. See how long it works OK for. If it works without going off (assuming it was very dusty inside), then replace the back. If it needed a fan to keep it working you may find out what needs replacing.

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

SOURCE: No Color on my Audiovox AVT-1498

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.

My audiovox 13" monitor in my van shows only a 2-3" bar of gray static through the center of the screen. What is the problem? I can't seem to get my video channel or the menu even with the remote co


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.

When I turn it on I have only a vertical line in the center of the screen. I can bump the front of the screen and it will come on sometimes. It's a Audiovox AVT-1498


I bet the line is left to right in the middle of the screen!

This is a vertical circuit problem. The bumping tells me a solder connection/s on the output ic are broken loose or poorly soldered.

It is a chip (I will attach a photo of a typical chip--yours will not be exactly like it but you should be able to locate it).

The part in the photo has the generic number (LA...... which is one designed by Sanyo but used in many different sets) The chip will usually have between 7 and 13 pins.

All someone has to do (unplug set and remove cover) is take it apart, gain access to the main board (it may slide out or if open view of the bottom just turn set on its side after you locate the part---part should be fairly easy to find as it is always bolted to a small metal plate to cool it.

Take a good look at the pins from the bottom and resolder all of them.

9 out of ten times a 10 minute job.

if questions or need help let me know with a comment here.

No picture but have sound


RDD6 - I had the same problem with my AVT-1498. Took it to the repair shop who told me it would cost hundreds to repair. I figured I could find a replacement crt for less but was wrong - they don't make these tv's anymore, and really don't make any 12v crt's anymore period. So I decided on a 15" 12v ready LCD model which fit the hole where the old crt TV use to be. I needed to rig it to hold the LCD bracket but that wasn't too difficult. Then just hooked the wires back up. Good luck with your situation.
