Just installed an after-market roof-mounted 7" high resolution monitor, DVD player and VCP in my '02 EXL-NAV. It works real well except sometimes there are faint horizontal "lines" moving across the screen especially with the VCP (much less with the DVD). The system is connected through keyed power. Just wondering if anyone has thoughts on what the problem may be. Thanks in advance.

Are these horizontal lines that move up or down through the picture, spaced such that about two of them would fit on the screen at the same time?

That would be hum bars, which represent bad ground in the signal. At least, that's what it is in your home on your cable TV. (Usually it means that someone out back has tapped off the cable badly, either in a legitimate house or else has illegally tapped into it up at the pole, all using bad cable.)

Actually there are a number of horizontal lines adjacent to each other on 1 screen at the same time at a slight angle going upwards from left to right. I will check again but they maybe move upwards gradually.
