6600M shut down on its own, Flashing Red Light 6 times, buzzzing noise, Stuck on Please Wait.

This afternoon on 9/24/2019, I had the Radio on 20 Meters, and with out warning the radio went in to shut down with flashing red light and buzzing noise.

I powered down the switching power support, power backed up and and attempted to reboot the Radio. The Radio did a few strange things during the attempted boot up.

1. Flashing Red Light and no boot up screen with buzzing Noise.
2. Factory Reset with flashing white light, buzzing Noise and Please Wait Screen.
3. Sometimes with no flashing lights, buzzing noise and Please Wait Screen.
4. Disconnected Network Symbol.
5. The flashing red light keeps flashing 6 times.
6. Six red flashes: Input power under voltage

On the Wait Screen with the flashing white light and flashing red with with the buzzing noise, I can access the Version >, and get the option of v3.0.27 and v3.0.19. I can select the software. I will attempted to load it as it show the bar, and after that it just sits and goes back to Please wait none stop.

I looked this red light flashing 6 times, and it means: The in put power under voltage. I try a another power supply I have in the house. This is a 28 Amp Switching Power Supply, and it did the same thing as first power supply I was using. It seems to me that it not loading up the operating system at Please wait screen. could this mean a corrupted files or operating system on the SD Card? I even put this under a Help Desk Ticket around 4:30 PM Cent Time today.

Any advise and help would be appreciated .

Thank You,

Julie H B KC0TMD

    With the buzzing sound, and knowing  there are capacitor across the input power to the radio, good chance they are about to go pop...

     i was wondering how old is your 6600m?  i also have 6600m  but have not experienced this issue but have seen it a few times here on the community...

    Definitely need to file help desk ticket....
