Thanks Scott, had that exact problem, applied some acetone on a Qtip, removed the protective "stuff" from the screw and slightly released the little screw: works like a charm. Thanks for taking the effort to post this solution.
Many thanks. This worked for my Yamaha CR-220 receiver. I didn't have to remove the meter. The set screw was accessible from the rear of the meter. Before concluding that it was a stuck meter, I checked the on/off station voltages at the meter terminals first. In my case, AM on station was 0V, off station -90mV. FM on station was 0mV, off station was up to 32mV, pos and neg. Just thought I would include that bit so that people can understand the low voltages involved. Testing the meter with higher votages wouldn't have done it any good.
Glad it worked for you, and you are correct about the low voltages. D'Arsonval meter movements are low-resistance devices that respond to current, not voltage, and because they can be quite sensitive, they need little voltage to cause enough current flow to actuate them.
Have a sony tc765 with very nice big VUs but they move really slowly and not vibrant at all. It looks like others have the same problem with their 765. Any advice to fix them
That may be an electronic problem rather than a mechanical one. I seem to remember this from repairing a 765 in the past, and there were electrolytic caps in the meter circuits that needed to be replaced.
Hi Scott I have a Yamaha A-100a and it works great but the VU meter somehow doesn’t move or just for a little bit with max power input. Any suggestions on how should I fix it ?
I have a Marantz 5220 tape deck that has VU meters. One of the meters occasionally gets stuck at 5 or 1 DB. Usually those two stuck points. If I tap the top it will release and move a bit and then get stuck there again haha. Dumb question but do you think this fix could help? Or is it more concerning it usually gets stuck in the same positions?
It sounds like something is catching the needle of the affected meter. I suspect that the plate that the scale is printed on has slipped out of place and is catching the end of the needle. If you're handy with tools and have a steady hand, you might try removing the clear front from the meter and taking a look to see if the meter scale has come loose. If so, you can probably just press it back into place, and the glue that held it in place originally may well grab hold of it again, fixing the problem. If the scale does not appear to be loose, play a tape or send some audio into the inputs of the deck while the meter is apart, and let the needle swing to see if it's catching on anything. If not, then you might want to loosen the bearing screw JUST A LITTLE BIT to see if that helps.
@@ScottGrammer thank you so much for taking the time to reply! I haven’t had a tape deck in years and never had one with meters so I’m out of my wheelhouse. I’ll give this a try tho as it seems pretty straightforward. It doesn’t happen unless I’m playing a tape that’s pretty bass heavy where the dbs elevate (played a bob marley tape that really got the meters moving haha). Thanks again and happy new years!
Sorry for the poor audio, I used a head-worn camera to make this video, and its internal mic is the pits.
Thanks Scott. That’s a simple fix for an annoying problem I’ve had in the past.

Glad I could help.
Thank you very much, your video helped me a lot in repairing a POA-A1HD🙏
Glad to be of assistance.
Great video and to the point, thank you
Thank you, and you're welcome.
I had a stuck VU on a Tascam 122 MKiii and it worked! Thanks!!!!
Glad to be of service!

@@ScottGrammer i will check 🙂👍🏻
Cool channel bro, just subscribed.
Thanks! I looked at your channel just now, subbed as well.
Thanks Scott, much appreciated.
Thanks a lot Scott, regards.
Thank You! Working.
Glad to hear it.

Without seeing it, I would not know what to tell you.
gonna try this later thanks

Going to try this on my space echo 😅 wish me luck guys lol
