Hannspree HT231HPB - PSU Question

[JFunc]

Hi there!

I have been given a non-working HT231HPB monitor to repair. The owner has misplaced the stock PSU, so I will power it from my bench supply.

However, before I start troubleshooting it, is there anyone out there that could please tell me what the polarity of the stock PSU is?

If you could tell me if it's center pin positive or negative...even better, if you could post a picture of the power brick label, that would be extremely helpful.

Looking forward to hearing from you!

Cheers!

Andy.

On further internet investigation, and squinting at low res images...it seems to suggest center pin positive, but if someone could clarify for sure, that's be amazing...

For unknown connector polarity I've traced from where the centre pin enters the PCB to where there is a polarised component, an electrolytic capacitor is a good one to find.
