Was not too sure where to post this.
I have fitted a 12V TV to the rear of my vehicle for my grandkids, there is a whine that increases and decreases as the rev's fluctuate. Much like the old unsuppressed car radio' in the 70's.
1. The TV is driven by an aftermarket Radio / DVD / Sat Nav combo specifically made for my Toyota.
2. The DVD player connects to the TV via a 5m RCA cable that runs from the front of the vehicle, down the centre of the vehicle to the rear.
3. The power is taken form the factory fitted 12V plug in the rear of the vehicle.
4. There is no whine when the motor is not running and with full ignition on.
With the TV on full volume there is not whine when in any mode other than DVD. The minute the mode goes to DVD the whine begins, even before the DVD initialises. As the whining sound is not present in other modes (radio, iPod etc.) I have made the assumption that it is not power related as then the whining would always be there.
Now the cords are you standard el cheapo's that one would get at any consumer electronics store. All three RCA plugs are connected at both ends, DVD and TV.
So the questions would be;
a) Am I thinking in the right direction in that it is not power related.
b) How do I fix the problem?
Cheers
