Hi,
One of the possible causes I have missed up to now: sticky brushes.
Check whether these are able to move into their position in order to make
proper contact to the rotating parts. At least mine did not and I had a
similar light show.
All diodes were looking o.k. when measured with an ohm meter.
Cheers,
Hans, finalising the carpet this weekend....
