Here’s how I wired in the new power supply. Checked the voltages and polarity, all good. When I plug in the AC power, the power supply green LED lights up and I get 24V and 5V output voltage from the new board. I connected the ground (all white) wire to the -ve 5V lead and the other two wires on the +ve lead. Any suggestions on what else to check?

Thanks for posting this repair solution. I purchased a replacement power supply board for my Bar 48 that won’t power up, I wired it in and checked output voltages and polarity but the unit still won’t power up. I’m at a loss now, any recommendations on common other causes? My Bluetooth sub may be a candidate for converting to analog input (might as well get the most out of what’s left).
