CR-2040 power meter stops moving

Got this receiver about 3 months ago and one meter was not working, gave it a few taps near the meter and it woke up.
Now it has stopped again and i am wondering if there is any "fixes" or adjustments to keep this working, possible lubrication points?

Thanks for any help

Avionic should fly in here any minute and help you out!:thmbsp:

Monitor the voltage across the meter. If the voltage is there its a meter issue. If no voltage is present, its a continuity issue (wiring/solder connection)between the amplifiers output and the meter. Assuming that the amplifier is producing a good clean output.

thanks, i will open it up and check the meter connections.
