My FLEXVISION 13in. color tv/monitor model avt-1498 in my dodge van i just bought will not show the picture only sound. the screen is all black but there is sound. i have the manual right next to me. i tried brightening the screen, changing channels and switching from tv to dvd to video2 but its all black and just sound. im going on a trip tomorrow and my kids need the tv. i need help on fixing it, what do i do?

you dont,you throw it away and get a flat screen hdtv for cheaper

Good news - don't worry about this TV anymore and just trash it out the moment you buy a new one!

If this is connected to a VHS or DVD player or roof antenna, when problem occurs Check to see that the video in to TV cable is tight. If so you my need a new cable

Welcome to FIXya

did you try to unplug it and plug it back in
or maybe goto the menu and try to redo the stations

make sure you have the tv pluged in to a power strip

hope this idea helps out if not please let me know have a good day:)

hey
ply with שךך switch in front,if u already do that so its can be a bad switch burn related fuse.

Make sure that the color control level is set to the default or 50% to start with. This should be in the Video menu.

The colour for the tuner and for the encoded base-band video uses a circuit area called the colour demodulator. It is possible that this cirucuit area has failed and needs servicing.

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.

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.

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.
