Hijackzx1,

Does your 08' eby701 cause any noise in your system? The reason I ask is my PC is perfectly silent until I turn on the EBY701. With it on there is a high pitched whine. It is definatly worse when first starting the monitor in the morning. Calms down after 10 minutes or so, but never goes completely away. I suppose it could be the close proximity of the Screen to the Motherboard which is also installed in the dash, but I didn't have this problem with my previous Lilli. Everything is grounded to one point with only about 12 inches of wire.

Any help would be most appreciated.
