Wondered if anyone can help. L322 Range Rover V8 Supercharged 2007

The issue an AV system that keeps cycling and turning itself off and on. On the face of it all modules appear to be working as I can select TV/Radio/CD and they all generate a signal (before it shuts down 15 seconds later).

Its seems like a MOST issue because the input selector seems to blank out the inputs. In essence behaving like this (I have the same system) -

Have run the error checks and done the diagnostics:

B101025 - Rear video input failure

B100E25 - TV/RSE Video Input Failure


Run the MOST test - It seems to be "Net On" and have a "stable lock" (until it shuts itself down) but nevertheless lots of white lines on the test pings so something a miss


Things I have checked:

1. Battery voltage and alternator seem good
2. Have cut Bluetooth unit out of MOST loop - this seems to be a common fix on-line, but doesn’t seem to be the Bluetooth unit
3. Have checked for water ingress where the units are installed - cant see anything obvious.

Really hoping there is a MOST genius out there who can help me.

Hello Matt14

Did you ever resolve this issue? I have the same problem and looping out the Bluetooth module worked but only for one ignition cycle. Back to on/off sound again.
 
These are the messages I get

So far so good, put in an MOST loop from ebay and reset the head unit. All working and fault codes have gone
