Hi All \ Alan, I'm running a Mega60 out of the DMX output of a P12. I've had it running in testing for over a month now, but never ran for more than about an hour or so. I did a final test on Sunday night, and my show commenced last night, and i've noticed that at some point after about 2 hours (the show runs for 3) all the lights attached to the M60 go full 100% white and stay that way until the board is power cycled. This happened on both nights - Sunday I noticed it about 5 minutes after it happened, cycled and all returned to normal - but last night I didn't notice until the show finished at 10pm, and these elements were all still on. The board was purchased somewhere between March and June this year, so I assume it's running latest firmware (says v1.9 on the board) I'm running LSP 2.8 Advanced, all multicast (all told there is about 600 channels). I'm only using zone 1 and 2 of the board - zone 3 and 4 are empty, and therefore not powered. If anyone's come across this and has any solutions, i'm well open to them, otherwise i'll await Alan's advice. I really hope it's not a faulty board!
