Speedometer clock

Hi everyone, I have an issue with the left clock on my 2008 rocket classic. It's the 1 with the Speedo. When I start the bike the clock lights up engine management light stays on oil light stays on and the LCD display shows 888888. Anyone seen this before or know how to fix it. I plugged my laptop in and it shows no fault codes

Does it sweep when you switch on?

If it were me - I would lift the tank - find the connector and unplug. Then remove the clocks complete with sub harness, remove the rear covers and the the connectors and give the whole lot a **** good cleaning.

Reassemble and see. My gut says it is an EARTH FAULT
