I have a KEF PSW4000 subwoofer. It has worked well for c5 years.
Recently I changed my AVR to a Yamaha 777. Initially I had problems setting the subwoofer up and it was never recognised in the auto setup, i.e. never output a sound. Swapping around lots of cables, turning things off and on, etc. eventually sorted it, but it wasn't very scientific and it wasn't obvious what the problem was.
Now the problem has re-emerged and once again I can get no output from the sub, although it may be different this time.
Everything in the AVR menu is setup as if a sub is connected. A sub signal is being output according to the amp display. If I power off the sub at the wall and then power it back on again, the sub switches on and it outputs as normal for about 2-3 seconds, then stops. Everything else appears functional on the subwoofer, e.g. the volume, crossover and phase adjusters, but whatever I do I can't get any output. If I switch it of and on at the wall I get the same 2-3 seconds and it repeats. It's almost as though some sort of protection is kicking in, but for the life of me I don't know what.
I've sent an email to KEF, but obviously open to any other suggestions. It's a very sizeable paper weight at the moment!
