Questions About The Numark MixDeck Onboard DC Port

[TurcoLoco]

Hello all,
I have a Numark MixDeck from 2011. The power supply seems OK but the DC port within the deck itself seems broken or loose.
The device will not power on until the DC connector is inserted and then turned a little counterclockwise then it works but if you touch the cord, poof!

I am guessing the cube shaped DC port on the board is bad and needs to be replace?
Does anyone know what this part is called so I can check on DigiKey or somewhere?
TIA

I think I lucked out as I believe I located it on DigiKey: https://www.digikey.com/en/products/...T-4S-S/9990090
Can someone at least confirm these are not fixable, meaning I just need to replace the part?

TIA.

If you know the pinout on the jack that corresponds to the wires inside the cable, just unsolder the jack, cut off the plug on the wire and solder the wires to the traces on the board. Cost = Zilch.

As for the jack… I can’t see the bottom of your board to verify the pin arrangement to see if it fits to the PCB.

Unless I didn't quite get it, what you were suggesting would permanently fixate the power to the unit, right?
I can't do that because it is not mine.

I know the pictures are a bit limited but looking at it from the top the pin locations are a match as well as other details. Data sheet also confirmed the measurements too.

I am trying to not take it all apart because I want to see if something I tried fixed the problem or not, using a special bent tip needle-nose pliers I pinched the metal tabs on the sides inward a bit more.
Not sure if these little tabs located on the side holds the connector firmly in place or not but I want to check to see if that helped before taking the board out.
Thank you!


PS. After 20+ posts, site still needing human verification? Come on!

Aah… well, if it isn’t yours, a new jack it is!

Take the board out and inspect the solder joints on that connector, or if in doubt, apply fresh solder to the connector pins; cracked solder joints can also cause the issue you're describing
Also to check if the replacement connector fits the same footprint on the PCB

Thank you. I was going to right after I check to see if the issue still existed or not.
There are like 10-12 screw at the bottom where almost everyone of them had various degrees of cracks where the screw screws into.
I had to do something so, I dropped a little B-7000 around them and for the ones with the big cracks, used mini clamps. One was completely broken off.

Tomorrow should be totally cured then I will reconnect all the cables and check. If no go, then since I will have to take the board out for the new part, I'll double check the solder joints.
The port seemed fairly stable and firm though but you are right, doesn't hurt to check.

Thank you!

Isn’t B7000 flexible glue? Should have used epoxy.
