iCharger 106B+ 'Connection Break Down' (Over Voltage Repair)

[Ampelgelbbremser]

I changed both components, but now the charger is sucking current like hell. (current is limited to 1,5 Amps and the voltage breaks down) The display stays off and nothing happens.
If I unsolder Q26 the charger "works" again. Display turns on and everything seams normal.
Any idea?

I had the same problem with my iCharger 106B+. Overvolted it to 32V for a few seconds by accident.

Replaced D16 and Q26 with the following from eBay and it's working and no longer saying 'Connection Break Down'
Q26: BC807-40 Transistors PNP SMD 45V 0.5A (marking says 5C)
D16: 0.5W 20.0V ZMM20V SOD-80 LL34 SMD Zener Diode

Thanks for the advice.

I replaced D16 and Q26, and its working again.

Here are the exact parts used...

The first thing I had it hooked up to was a 24V meanwell turned down to 16V. Apparently it has a sufficient voltage spike on power up to cook the charger. These things are a bit more sensitive than I assumed.
