Help! Do I Need A New '2x Mobo?

[aaron11193]

Hey all...

I need some help.. I was doing a D-Pad mod (Modding My '2x D-Pad, Spare GBA Parts.) and i accidentally pulled the copper ring out of a contact for 'left' on the gp2x's PCB...

Is there another place where i can make the connection to get left direction working?

Ouch, that hurts... I hope you can get some guidance on how to fix it soon

Ive found a contact INSIDE the hole that i can use but i cant get to it.... a blob of solder wont slide down the hole... and i stripped part of the copper that goes to the contact hole and tested that but it doesnt register...

I think the left contact routes to one of the internal layers. About the only thing you can try is cut the leg off a resistor or capacitor and feed it into that hole, soldering at both ends. Hopefully it'll make a contact and you'll be able to put your wire on that.

Other than that, there's not much you can do.

A gentle dremel grinding may reveal enough of it. I once repaired a multi layered mother board by stabbing it with a safety pin, snipping it off and soldering a lead to it. Good luck, trace around, maybe you'll get lucky

Thanks for the quick replies

Ill try what Squidge suggested since i dont have a dremel...

Ill post back when im finished

Ack, that sounds nasty. Hope you get it sorted. Maybe this is motivation enough to buy a Dremel.

Bunnings have "Ozito" brand Dremel clones, they're actually quite good. Less than $50, three year warranty. Do eet.

Id buy one but i dont have a job atm so lack of money lol

and im in a very remote town so no dremel shops around =[

Hmmm.... I tried soldering a piece of a capacitor leg into the PCB...

It made a connection with the copper inside but also with a ground somehow and when i play with the piece of capacitor it reads left and it will stay reading left until i play with it again...

I think i might need a new mobo....

If anyone wants to swap a gp2x with a broken screen/snapped joystick etc. (non-mobo related breakage) for my mobo then ill do that... but i doubt anyone will... lol

 

[gruso]

The other end of that rail has to pop up somewhere. Pretty hard using an ohmmeter to find out though, when you can't make positive contact with the known end... I think you need a good mobo to test on, or someone to find out using theirs. I'd give it a shot if i had an F100.

Yay Dude looks like you destroyed your Gp2x. :unsure:

Sounds like there is a ground connection nearby and you have used too much solder on one of the board. Try sucking some of it up to make a smaller, smoother solder join by using some solder wick (do NOT use a solder pump, these are too vicious and could damage the board even more)

Btw, what type of solder are you using? I always think 60/40 is the best for repair jobs, I hate the lead free stuff.

 

[aaron11193]

I dont have any solder wick... and yes i use 60/40 solder...
the unit itself still works perfectly just cant use left...
