Analogue-sequencer

Hi,

My P3 doesn't start up anymore. Two days ago I wanted to play with my friends, I had spend 2 days building my machines and P3 in a flightcase, everything matched perfect, but when I powered the flightcase on my P3 frozes at start up. The flightcase came from my car and was cold, and it was warm and dampy inside so maybe I was to quick putting power to the machines. 
The P3 hang emedietly, showing 8 burning little leds, 4 for the upper row functions, and 4 for the lower row. The LCD upper row shows all burning squares, and the lower row shows nothing. In the meantime I tried the F1-7 reset function and the reseruction procedure but nothing seems to have any effect. Anyone any idea???
