Wow, that was really impressive. Glad you were able to work your way around it.

[Jespber]

I had a problem that my screen was loosing Power and the middle pin in the dc Jack was loose just like in the video, but i did not have do modify anything or replace anything. I just heated up in the middle of the dc jack at the curcuit board and added some soldering and then the pin was no longer loose and worked fine again after I put it together. So if you are lucky its a really easy fix!

Nice video

[rustynail]

you skipped the hard part, show us how to take that cover off!

[sneaky_krait]

That’s incredible, I was asked to fix the 24 inch model of this screen and it had exactly the same problem

[azurplex]

This style jack can be used on battery operated devices too in which case the negative pole is disconnected when the adapter plug is inserted.

[necromortem]

could you get the name or number of the part you desoldered? I'm try finded but don't luck,
Great video

[j.lietka]

Great repair video! Think the extra screws are there to frustrate you enough to where you will just buy a replacement board! 😂🤣 Thats a rather nice HP monitor!

[missoummohamed]

I see you are a professional, please I need your help, I have hp 27 es and I have vertical lines on the screen, I opened the back and tried to remove the adhesive tape after a black vertical strip appeared on the screen, what is the problem please, I have photos if you can see them and tell me what to do thank you from the bottom of my heart

The 'switch contacts' on some (but not all) DC jacks is in the 0V rail and is generally used where you have an alternative power connection which is 'disconnected' if the DC jack is inserted. I couldn't see an alternative power connection in your video but there may be one.

[Xorat]

That modification looks like its factory! Very nice!
I would have maybe taped up the old port so people dont try to plug stuff into there!

[mamadubalde]

Another great and easy job well done !!!!

[monshiiee-fox]

what would "blow" if you plugged in a power supply with way (way) too many volts?

[Dutch_off_grid_homesteading]

Heya repairing is plan A if it is not repaireble anymore we have plan B nice that plan B works well done

[vnicks]

I have same model and sceen is broken… is it repairable?

[tmc]

Whats the name of the part you replaced it with

[thegroove]

To summarize what was the problem and the fix?.
