Can't control sound ...Gets LOUD.... Audiovox not helpful to date
I have the 15" Monitor in my Motorhome. Picture is fine but the sound spikes with no warning - Can't be controlled by remote or by actually pushing the unit's volume buttons.
Audiovox warranty is a "GOTCHA'" deal in-effect "Buy a new unit"
BTW: I just discovered this Forum.
In the event no one can suggest a cure, I am thinking the only workaround might be to get a new in-dash DVD Player (w/FM and 4 speaker sound output) and use THAT unit's Amplifier.
For Sat TV - run an S-Video cable fron Direct TV Box to Audiovox monitor and run the RCA sound cables(?) to the new in-dash DVD player amplifier. Does this make sense?

Re: Can't control sound ...Gets LOUD.... Audiovox not...
Does the sound spike no matter what kind of input you are using? At first I was thinking there is a break in one of your input cables. Otherwise it could be a loose component inside that wiggles as the motorhome moves or someone moves around inside, it could also happen to a loose component when the ambient temperature changes.
I would open up the unit and look for any loose components then resolder their joints and see if that helps.

Could be a hardware issue, If the screen has a power light, does it change coulor (often green to orange) when the problem happens. If so its the screen inst getting any signal. It could be a connector or cable.
It is very simple to troubleshoot any sound problem by checking the followings:
1- Speakers ( Check for continuity)
2- External sound jacks( maybe short circuited or need re-soldering)
3- Sound amplifier IC
4- Sound amplifier IC supply voltage ( Can be tested)
5- Sound mute function ( Check that it is not activated)
6- Volume control
7- Sound settings on the main menu
if thats the picture of the transmitter to program it you have to : turn the ignition to on position. press and release the programming switch 3 times... press and hold,for 3 seconds, the buttonof the transu wish to add until the parking lights flash. this would mean the transmitter has been learned. repeat step 3 for each transmitter... turn the ignition off to exit the program mode..
do not let 15 seconds pass between steps.
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.
Is there anything going on in Control Panel, Power Settings? Such as an auto off? Sometimes getting the monitor to come back on after it goes to "sleep" can be tricky. Usually a keyboard stroke works better than mouse movement. It almost sounds like a hardware problem and I would contact the manufacturer and see if it's still under warranty. I'm assuming the PC it is connected to isn't going off?
