I'm new to this site so forgive (and redirect) me if this has been discussed already.
We have a 2003 Odyssey with the rear entertainment system (RES). There's a component, supposedly integrated with the monitor, responsible for headphone sound. Ours has gone bad and the result is that headphones don't work for very long - after 30 minutes or less the sound turns into a high-pitch whining. This is true for both the wireless headphones and for headphones one plugs into headphone jacks.
The DVD sound always works when using the car's speakers.
A dealer offered to fix this for a mere $1600 (this may have been parts only - a new monitor). There HAS to be a cheaper way to fix this. Has anyone else dealt with this problem? If so, how?!...
