Razer Blackwidow Chroma Tournament edition repair. Broke a LED trace.

[GTheGecko]

Hey, as the title mentions, I ripped a trace off. The old owner tried resoldering the W key switch but snapped the 4pin LED pins instead of desoldering them properly. Because of this, the W key had no light, so I tried putting in a different LED in and accidentally ripped a trace that went to a microchip. Unfortunately, the keyboards middle row now double clicks 2 buttons at the same time, like g and space, fg, dc, enter and backspace, etc. Any hope of making a cable trace and fixing this? Thanks!

Wow. What a mess. That poor board. Was somebody trying to practice learning how to solder on that?

How did the trace tear all of the way from the led to the chip? Did it even rip the leg of the chip off with it?

I don't think it would hurt to try to run a wire directly between what's left of the chip's leg and the corresponding pad. I imagine there's nothing left of the pad the leg was attached to either? Hopefully that doesn't run anywhere else.

Looks like the leg on the chip that the missing LED trace goes to is also missing, if it is you're not going to fix that.  If there's still a little bit of the leg left and you find an expert solderer with a tiny tip they might be able to solder a jumper wire but I wouldn't be trying to do it, too small.

As to the double keypresses it looks a lot like the C shaped jumper wire is connecting the switch pin on a key on the bottom (top?) row to a diode for a key in the next row, and in another column.  It's a double sided (at least) PCB and I can't make out any traces to say for sure but that doesn't look right.  Which are the two keys closest to that jumper?  If you can get a close up pic of the area with the traces showing in the shine that might help.

The corresponding pad is definitely ruined. The leg has been ripped off, not sure if fully, very hard to see with the naked eye. I tried running a wire to the "pad" and the microchip, but to no avail. Unfortunately I can't see the traces on the other side of the PCB because of the metal backplate. To take that off, I'd probably have to desolder all of the switches and LED's.

Hey, not sure how to properly reply on this forum, hopefully you see this.

The leg might be fully broken, hard to see with my naked eye. But the C shape jumper is for FN key that wasn't working at all. Doing this, I got it to work before I broke the trace trying to desolder W key. Do I try and desolder this trace and hope that works?

Also, any idea what that microchip might be for? If it's only for RGB control, it's not needed for the keyboard to work, if not than I'm not sure. The keyboard started bugging out after the trace broke. Thanks!

If you type the numbers on a chip and "pinout" into a search engine you'll probably find it, no way are there enough pins for that to be running all the keys on a full size keyboard and it's connected to an LED so probably some kind of RGB controller.  Unless the only ground connection to that chip happens to run through an LED pad which is very, very unlikely.  The pinout will confirm, if in doubt post the numbers or a link to what you found and I'll have a look.

I would try disconnecting the C shaped jumper and see what happens, as above I can't really help more without being able to see what's going on and black (and white) PCBs don't make clear pics.
