Re: UV-390 Plus GPS 10W Screen Backlight Not Working

Hi, From your secure register, it's part of the rare UV-3x0 10W Plus that doesn't requires a specific version (Backlight/PA pin aren't swapped). You can still get more power, as the one displayed is a faction of the full power, valid for 5W radio, so for yours, they're 50mW, 250mw, 500mW, 750mW, 1W...

I flashed my 390 Plus GPS with the OpenGD77 firmware, but after flashing, the screen displays without the backlight turning on.
