Hi James,
Have not had too much luck with the local distributor. I have a friend who used to work for for sony and now is the optoma service engineer, I was wondering if you could send me the part and I could have him replace the power switch?
I also have another problem, since the 9b was having this problem I picked up a 8bst (second hand), everything was fine until now, but now suddenly the 8b pops the circuit breaker the moment i turn it on. I changed the power cables, changed the plug, switched the system to a different set of breakers but still no luck.
Just to ensure that the culprit was not the wiring in the house I checked the 4b using the same combo eg, power chord, plug and breaker and the 4b works without any problem.
