Group,
Thanks for reading this.
Is there a troubleshooting thread, if so please re-diriect aka bump, I've noticed many bits and pieces here and there but wonder if I'm overlooking the obvious.
In building my second GMx5x5, I cannot get the main LED to light, however all others do. It seems there may be a short somewhere on the main lines but tracing continuity doesn't concur. Caps are properly polarized as are diodes. Hex converters and iso opts are proven tested in first unit, which works perfectly. I'm concerned I may have a bad main chip. This is a rev 1.12 board. Suggestions are welcome.
I also notice a chip replacement order up but very slowly filling. If anyone has a spare chip for sale I might be interested.
Best regards,
Jon Pyre, Orbitalgun.
