Troubleshooting my Dead PSU

My Q1755 13.8v 23A switch mode PSU just died.

It was doing so well for over 1 year until I did something silly by running 2 ichargers 106B+. Each charger was charging a 6S 2650 Lipo and was set to 9.9A

Usually the chargers would just dumb down to 4.5A but because it was for such a long time I must of stressed the PSU until it went "POP". The PSU was very hot making me think it was a thermal overload and cooked something inside.

After opening the PSU I found no indication of dead components, the slight smell is gone too. When you turn on the PSU the switch will light up to turn off & on, but no output voltage.

So now the journey begins to find out what is wrong & replace to get it working again.
