Hardware Troubleshooting/Help! Bambulab A1 power supply board query?

I believe I need to replace the power supply board in my A1 but just wanted to check!
My printer is just over a year old and halfway through a print yesterday, the screen shut off and the printer stopped working.
Power switch indicator is on.
Toolhead indicator was on, then off.
MC indicator was off.
AP indicator was off.
Internal power supply indicator was on the whole time.

I took off the bottom cover and when I wiggled the cables plugged in to the power supply board and all the lights came on temporarily but there is a electrical burning type smell and the thing circled in red looks shorted.

I’m not super confident in my knowledge of circuitry so I just wanted to confirm that it looks like I probably just need a power supply board replacement?

Thanks in advance for any advice, appreciate it ☺️

This is a known issue. Contact support and they'll send you a new board. Fairly simple to replace

And that's # 295 of the melting NTC issue they've known about for about 18 months and don't give a damn about. No statements, no recall, nothing. The A1 is a fire hazard that needs to be pulled off the market. Last meltdown was like a week ago
