Hi,
I am new to electronics, so please excuse any errors and feel free to point me in the right direction!
I have a 7 year old motorcycle with an electronic (LCD?) speedometer and buttons for switching between displays, but one button has stopped working. This is a known failure for this dash but it seems that no owners have been able to fix the problem and manufacturer replacements also fail. I am trying to understand the failure and then see whether a repair can be made, the part is very expensive to replace!
There is a theory among some owners that UK bikes suffer the failure more than American bikes, maybe the problem is associated with climate and therefore corrosion?
I have removed the dash from the bike and removed the workings from the outer casing for inspection.
I carried out a continuity test on the switch to see whether it works, and it seems OK.
I can see what looks like corrosion on the PCB trace, but I would like any feedback on whether this looks like the problem.
The PCB is printed with 'NS 06901'.
I will try to attach some photos to show you what I can see.
So...
Do you agree the problem seems to be corrosion of the PCB trace?
Is it realistic to make a repair to the trace?
To get access to the trace, I think I need to remove the PCD display, but this seems to mean removing the solder for all of the pins (see photo), am I correct?
Thanks
Matt
