Crap, sorry for the late reply.  I'm subscribed to the post but I'm not getting the notices..

Anyway, I bought the board second hand last year and had been using it almost daily.  About two weeks ago it suddenly stopped working altogether.  Nothing happens when you plug it the pc.  I tried on different computers and still nothing.  I have a soldering iron and tried reflowing the usb connector pins as someone suggested but that didn't solve the issue. 

Here are some pictures of the pcb, but I can take more if you need to see something in specific:

Photoelectric and mistakemistake investigated the PCBs that came with the LZGH when they came out. They found poor quality all over it.  Not surprising that it failed,  to be honest. You may need a new TRiK PCB.

Have you tried to use a different usb cable?  Sometimes it's just the problem of the cable.

Bummer.  What are the odds of finding a replacement pcb?

Edit: Might be pricey atm but any of the A87 PCB's will work. The trouble is finding one...

Oh you don't use any led, even capslock & scroll lock. How to check Trik is supported power source?  :-X
Please try solder some leds to check.
