Need a replacement battery for audiovox- D1708 is flat and attaches underneath the unit

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.

ALL The Best
