MTH WIU broken power connector

I've repaired at least 6 of these at this point.

See this topic with pictures, edit the picture or post a good picture of your damaged board.

This is @gunrunnerjohn 's picture I edited from that previous topic specific to this discussion.

I assume you most likely damaged the capacitor nearest the jack? That is a nice to have but not "strictly required" component IMO.

On severely damaged ones or instances where a customer attempted self repair previously, I have just used a different electrical connector system and wires rather than a jack mounted board.

One of my recent repairs where the previous person attempted repair and really ripped up the board. I had no choice but to go external wiring and connector rather than direct board mount. It even ripped the positive trace hence that solder blob repair.

Not the best cleanest repair, but the fact it works makes up for it.

For illustration again picture by @gunrunnerjohn so that you can better see what a good clean trace looks like.

You could either scrape off the green solder mask and solder to a point on the trace, or solder to one of the circled solder pads all part of that 5V trace.

So the cap you pointed out does appear to be the same one although it is soldered differently in my case.  It is literally soldered to the broken off connector. 

Since all the boards pads are ripped off, I think going with a different connector would be easiest.  Thank you and @gunrunnerjohn for the info!  I just wish I saw GRJ's original post before...

Again, in my most recent example, the previous repair attempts or the jack damaged ripped off any evidence of that tiny surface mount filter cap at the jack. Mine is operating without it. That sorta T shaped trace was damaged and i had to rebuild what was left of it. That whole area where that tiny capacitor between 5V and GND plane was gone.

That could be repaired with a jack like the factory only with more adhesive (JB-Weld) so it isn't so fragile.  As long as you can jumper to the pads, no problem.  I've fixed a lot worse than that with the factory jack.

I had one of these brought in that needed this repair and the customer requested JB Weld to ensure it wouldn't break again!

Hi I had to repair one where the jack was completely broken off as well, the original metal tabs were never soldered so the customer easily broke it off replaced new jack soldered tabs and WIU was repaired and sent back to customer! he was very satisfied!

I always solder them better and put JB-Weld on the sides to insure it can't come off again short of an atomic bomb.
