So I’ve looked through posts on the RX5350 with zero about output for meters. I have an issue with right meter 0 reading...left works fine. FM signal strength on right works fine. Both VR for meter output work fine. Any ideas????
I did Bobby thank you 😊Fatdog said:Be sure to grab the service manual from the library if you haven't done so already.

Thank you but the meter works fine for tuning strength. So meter is good. Connection good and vr pot goodtoshik said:Connector would be #1 to check
I have cleaned the switch a couple times with no changes.Transistorized said:Hi Bill. The readings do appear low for that right side. Since the sound output is normal the weakest link in this setup IMO would be the switch that selects the meter from Tune/Batt back to VU. Wondering if the signal is getting lost coming out of that switch?
Thank you Norm I will be working on it tomorrow since I have off work. I plan on lifting leg for better testingSuperduper said:Oh, and I forgot to mention... when you test the junctions of Q204, remember that it acts like a diode so depending upon how you have the meter hooked up, you may find one direction with low resistance and a different measurement from the other direction. Ignore the lower measurement and go with the higher measurement. Or ideally, lift one leg of the transistor first. I presumed you already know this, to factor in the transistor in the circuit but if you didn't, then take that into consideration.
Superduper said:"...........To replace, cut one trace leg to R238 or drill out the via that supplies it to take (old) R238 out of circuit. ........... Make sure in the process you do not inadvertently disconnect R239 from circuit or Q204b will not get bias current and there will be no change.....
baddboybill said:Collector voltage was fine until adding new R238 resistor. I pulled R238 leg and still get just a 1.33v
Just replaced R239 with no change
