Hi All
I have a Mirai T321154 it turns off after about 5 seconds, I am guessing it’s the power supply? The power supply is a Phihong PSM192-240 Dc output 6.4 to 8MA max. The Capacitors look fine no expanding of the cases (See pics). Does anyone know the pin out of the output so I can try an external supply? Has anyone had similar problems with this supply? Does anyone have a working supply I could purchase?

Thanks in advance  Mick
