3499415-WJr30.jpg3499415-1MuIo.jpgThere's no power to the monitor so I opened it up where the barrel charger fits there's 1 solder short. I don't know if its broken, burnt out of if its supposed to be like this. Can anyone please advise?

Thanks in advance

Looks deliberate to me. Can’t see a ‘leg’ in that hole, and looks like it has never been soldered

I notices the picture come on once when I picked uo the monitor whilst plugged in. Its not the plug that comes with that monitor so maybe a bit loose.

Possible I guess, although I’d have thought it was unlikely. I take it the power cord is firmly connected?
The ground solder connection looks broken to me (could be just the picture). Try and reflow the ground pin.
Maybe power cable is dodgy, if you twist cable does it come on. I.e monitor maybe fine

It has three grounds, unlikely thats the problem
OP are you able to take an image of the other side of the board near the power connector? Just noticing that there are no component ’legs’ at all on this side, which doesn’t tie in with the soldering top right of your image. Might just be the type of component though
Do you have a multimeter to check what is presented when the board is plugged in?

I picked up on you posting that the connector is a bit 'loose'? Barrel connectors are never loose, if they are then it's the wrong sized barrel or the spring connection inside has broken.
If it not the original 12v psu, check the pin size of the barrel connector is correct, some replacement ones are designed to fit multiple sizes, but many only fit one.

Also check the output current is sufficient.

Doesn't look broken to me, judging from the solid ground connections around it, but a picture of the other side would be useful to check.

How old is the monitor? How do the capacitors look?
