Ive just updated three ECG-P2 controllers to V2.7 with no real problems. At least thats what i thought till the last one decided to exhibit some strange behaviour. The unit were only providing gnd and data to a single string of pixels (50) but when connected to the 1ST output only 6 pixels would function. The second output worked fine and ran the test sequence both off the controller and from vixen. I reloaded software, downgraded software, changed plugs etc all to no avail. So i was just wondering if anyone else had seen this behaviour before i talk to ed re a faulty board.
