LR-9090 Signal Meter issues

[micaiahm]

I have a Lafayette LR-9090 with signal meter issues- it is not receiving signal. The meter itself was tested by putting voltage to it, and seems to be working. Checked variable resisters RV2 1k ohm is ok, RV1 is 17.61k ohm, but rated at 20kohm, could this be the problem? Any other ideas? See pic....

*Bump* I'm curious about this too

If I'm understanding you, You are getting good FM reception, strong enough for stereo, but your meter doesn't deflect. If that is the case check for 5.6 VDC at pin 7 of IC2.

Thanks, Will try. If there is no voltage there what would be net step?

I am getting 5.4v on 7 of IC2. Is that for FM tuning meter? My Signal Meter is the one that is not working. Any help????

Bad Variable Resister

Ok. Have a bad variable resistor. RV1 on TB. Anybody know what the correct adjustment should be for RV1 and RV2 on TB?
