back up camera solenoid or relay or ???

[Jeff Miller]

This is the '86-up monitor, I believe they later became Dotronix.

Your problem is a common one. If you remove the monitor (fairly simple
in your coach with the overhead mount), it can be repaired. I have
found that the daughter-board has an edge connector which is prone to
solder-joints failing, probably from vibration. Re-soldering the
connector on the daughter-board and mother-board should (and has always
for me) fix the problem. Supporting the board so that it can't as
easily vibrate/move should also prevent the problem in the future.

That is also a great time to reverse the image so that you can install
a new camera. The red and blue wires on the two-pin connector on the
mother-board need to be cut and reversed (red to blue, blue to red),
then a new BNC-type camera can be used. I've been very happy with ultra-
low-light .003 lux B&W cameras from Supercircuits.com, much cheaper
cameras are available from them and others also. The Dotronix monitor
is B&W.

casing that says Audiotronics is this a Hitachi brand. At times it
will play fine then go blank. I can tap on the case and it will
sometimes come back on other times will flash lines across screen. I
have moved wiring around running to case with no results so I think it
must be internal. Is there some place to get it repaired. Your thoughts
please.
