VU meter problem on Panasonic/National RX-7000

[BoomboxLover48]

RX-7000 sent for storage? Retrieve it back and send some other crap like a M90 for storage to the same place .
I love to see and pat my 7000 everyday.

I agree it is a great looking box. I send it because I have RX7200 and RX5350, RX5700 all hanging around. So also have M90, M80, M70, GF 777, GF535 (9000), GF2000, GF9797, GF9696, VZ3500 and so on...all my toys....so many to play wih

Nope. Cleaned everything, but still not working...

How did you clean it? Did you use Deoxit and then work the switches back and forth several times?

Please...

you might have a bad selector switch or a solder joint problem or a lot of oxidation buildup inside the switch or a bad component failed ic or bad cap,, any of these could be it..If you cleaned the record bar than its something a bit more technical. sometimes cleaning the selector switch or the function switch need some attention but I have seen in these pannys that some of the traces gets disconnected from the solder joint where if you looked with your eyes could not see a crack on the trace by using magnifying glasses and looking closely most of the time you can spot the disconnection Thats another possibility

Words of wisdom!
Great advice...
I had one of the VU meters non working on a Panny RX5350 and the issue was a cracked PC board. Yes that is a possibility. Check the PC board for stressed areas and corners. Look for any hairline cracks.

Trace the VU meter lines and look for breaks.
