GM950Plus Not powering on - sometimes
Posted: Sun Apr 27, 2014 9:38 pm
Hi all,
Have a UHF GM950Plus AZM34SHE2OE4AA UHF 450-490MHZ
When connected to a 13.5v DC supply unit will power on 9 times out of 10. In a vehicle, with or without engine running, it will NOT power on.
This was intermittent for a time, but is now seemingly permanent. Once it's powered on it seems to work perfectly, it just won't function on.
I can't believe someone else hasn't encountered this and knows what it is.
Anyone seen this issue and know how to fix it. I've inspected the board and there are no obvious issues. I'm suspecting a capacitor somewhere, possibly on the DC input or regulator, can some kind soul point me in the right direction please?
