Thanks for the encouragement Ian but I think that I can safely say that it is beyond help!

I actually had a nightmare installing the updates for all my speakers. Front left and right 5200SLs went fine as did one of my 3200s.

One 3200 took a couple of attempts as did the DSW. Two 3200s however took dozens of attempts over many, many hours but eventually completed ok (Sounds like bad flash to me but not much I can do to prove it).

The 5200VC failed from the start and progressively got worse the more I tried and after a wasted few days just now sits there with all its lights on the front. The messages I was getting on the display and the responses from the serial port have all stopped.

Both my dealer and Meridian support have suggested that the electronics be returned. Sadly it has been in this state for many a month now.

Cheers,

Tony.
