Audiovox avd300 will not display anyhing on screen. No sound, no picture.

It sounds like the flexible cable between the monitor and main motherboard might be bad. You might be able to get a new one from audiovox at audiovox.com.

Try pointing a flash light at the screen if you se something then you got a bad backlight in the lcd display, meaning the unit will need a new screen as the backlight is part of these mini displays 9 times out of ten that is what it is.

Due to the fact that when you move it it changes the problem it sounds very much like an intermittent soldered connection internally. That would require a shop repair.

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

Please post back what you find.

that kind of problem needs a tech right away.

I usually order from www.shopjimmy.com for tv parts myself.

Hi I just went through the same plight with the Shinco SDP-1750A I won from a local online auction. Sounds fine but no display what so ever. when I went to try and charge the connected battery to a standard 12v auto battery charger I noticed the display would spike with a quick flash as I connect the power. This is of course led me to believe the display wasn't a total goner. Charged it all the way and still zipola.

Seeing that I wasn't real excited about a DVD player that was nothing more than something like an old time radio show I decided to disect the monitor. VERY carefully and gingerly I removed all those tiny knat like screws around the screen frame (put them in a cup or such container so you don't lose what you can barely see). When I removed the dispay I carefully scrutinized all connections nothing looked out of the ordinary or visably at fault.

I then noticed that the main video ribbon interface type connector (wide see thru orange coloured flat cable which connects to bottom center of display was a bit crooked looking. I then unplugged and inspected it then plugged it back in and BINGO the picture was back bright and clear. I then made sure it was held on securely with some electrical tape and now it works a treat.

Hope this helps however this is only one of many things I suppose that can cause lack of display.

Sometimes the displays can't be sent to another tv or monitor. Make sure that isn't turned on. Sometimes there can be a short in the wiring if your unit folds up to play like a notebook computer. You can try moving the screen back and forth and see if the picture changes. If neither of these solutions work, contact audiovox and see if it is cover under warranty.
