    There is no battery in the remote. The remote is hard wired from the front a/c unit. Remote works fine for the front a/c unit, but not the rear unit.

    You can't turn on the a/c unit manualy only by the remote. the remote works fine for the front a/c. the remote does not have batterys The remote runs threw the front a/c unit from there it controls the rear a/c and furnace. i bypassed the front a/c and it still didn't turn on.

This might be a thermostat problem with regards to the aircon itself. You may check the remote by replacing a battery. If and when the remote reacts by pressing the button, there should be a display setting lit up on the remote. Since you have turned on manually the aircon and nothing worked, you may check the thermostat inside of your aircon by making sure the board is connected to the thermostat. Try also to reset the remote control by removing the battery and holding the power button. Then reinsert the battery again... You may check with the technician in solving the problem...

This happens when the battery is about to go dead. Please replace the battery of the remote.

In many units no option to use manually without remote and also it's not advisable. With your statement, I conclude your remote is defective and not repairable. Replace with new remote. Helpful?

TV screen goes blank but power stays on


Sounds like the CRTs are going into protective blanking due to the vertical output ic needing to be resolderd. Try resoldering the vertical IC that may possibly fix the issue.

When the screen goes blank, hit any remote function that will show up on the screen-like volume bar. If the display is missing as well, then you have a tv problem. If the volume display is there when the tv picture is not, you may require a software upgrade.

Wiring color code for xr-c5100


I am about to sell one on eBay - here are the connections from the installation paperwork and connector that I have:

Top row, left to right:
White - Front Left (+)
Green - Rear Left (+)
Purple - Rear Right (+)
Gray - Front Right (+)
Blue/White strip - AMP REMOTE (Max 0.3A)
Blue - ANT REM (Power Antennta Remote) (12V, Max 0.1A)
Red - Power (Accessory)
Black - Ground

Bottom Row, left ot right
White/Black - Front Left (-)
Green - Rear Left (-)
Purple - Rear Right (-)
Gray - Front Right (-)
BLANK
BLANK
BLANK
Yellow - Power (Battery)

One of the BLANKs is for the "Light Blue - ATT (attenuation for car phone)", but it is unclear which one. This wire is not on my connection block...

The circular BUS line to the right of the terminal block is apparently for linking to a CD/MD unit (cable supplied with unit)

The Blue 3.5mm socket is for the RM-X45 Rotary Commander (which attaches to the indicator lever)

Important notes:
If there is no ACC power line in the car, do not connect the red lead.
Ensure the power select switch on the bottom of the unit is in the B position, then press the RESET button (behind the faceplate).
This means that the display will be off when the unit is not in use - avoiding a flat battery risk.
(Posn A is for normal use, with red line on ACC)

The RESET buttom should be pressed after installation, before initial use.

Hope this helps.
