I have a GMC-320+ V5 that has been hanging on a peg in my basement displaying counts for the past two years. I noticed tonight that it was continuously displaying the startup logo and rebooting. I tried disconnecting power for a while, but it appears to have gone bye-bye. When I plug in USB power, it goes into this boot loop and also makes a squealing sound from the speaker. With the battery installed, it also boot loops (minus the speaker sound).

I presume these are not the symptoms of simply needing a tube replacement. Is there anything worth trying to diagnose or have I gotten all I'm getting out of it? I saw the sticky about measuring voltage, and with a standard multimeter I'm reading 160V on the tube ends when it's plugged in. There are no obvious blown components anywhere.

I do have a fairly extensive electronics workbench, so I can perform tests and repairs, I just don't know where to start. Or if it's worth it given the price of a brand new 500+.

Hi mastro, something in the configuration has been messed up. Just try letting it boot loop for maybe 1 day? Hopefully it's fixed by then. If it didn't work, (seems like you can do electronics) we can re-flash the firmware.

Thanks for the reply. It's still goneski, so I'd be up for trying a re-flash

Hi masto, can you email me your serial number? Thanks.

If you don't have it (unit is in bootloop) I'll need to contact support first.
