Faulty Teensy 2.0++

[nicstreet]

Does anyone have any good tips for troubleshooting (what I believe to be a) Teensy issue? Had my first built project completed yesterday and working on an Arduino Pro Micro. I removed this last night and rewired/re-coded for the Teensy 2.0++

I now have some very strange behaviour when the keyboard is connected and keys are pressed, issues appear intermittent and admittedly the board seems to function ok today minus some minor re-mapping of keys.

In fact bad behavior has just returned, top row is as follows:-

1 25tgb 35tgb 45 5tgb 56 57tgb 58tgb 59tgb 50tgb 5-tgb 5=tgb g

That should have read 1 2 3 4 5 6 7 8 9 0

Row 2 is as follows :-

qtgb wtgb etgb rttgb tygb tugb tigb togb tpgb t[gb t]gb

That should have read q w e r t y u i o p [ ]

g
b (g {return} b is what happens when return is pressed.

I've disconnected Column 6 and also tried the same with Row 4 and issues persist.

Any help appreciated.

Thanks

Nic

that most likely caused by some shorts. recheck all your solder points and check your naked wires

thanks Matt3o, I''ve tested all joints and they appear ok, I'll wire-up the Arduino pro micro again to see if issues persists, if not then dodgy Teensy.
