back up camera solenoid or relay or ???

[Ralph L. Fullenwider]

Howard:

This is the first I have heard of the Audiotronics being used. When Doug
Hampton, of PMMI, sent me the file on the back up camera system, I was
doing a write up on image reversing, there was only the Hitachi CT-911 in
the file.

The image reversing was done via external relays but the Color TV (when
Coach key was off) or the back up camera ( when Coach key was in the run
position) is done with an internal solid state relay.

Your problem sounds more like a cold solder joint or bad variable resistor
(pot) on the chassis part of the system.

As to service, I honestly do not know. PMMI did change some of the
circuitry by adding the solid state relay and there were a couple of board
traces cut and re directed in the gain control section. The P to P and
voltages remained the same though. So a competent TV repair should be able
to help you.

Safe travels,
