Faulty powered speakers


I have a Creative gigworks t20 series 2 powered stereo speaker set which have become faulty in a very strange way. Basically they only work for a second or so when the power is turned OFF (power cord removed). Other than that they do not work. The power light is on. I have checked the PSU and it outputting 27v as it should.

Any ideas what type of fault this could be?

Faulty power regulation internally - the circuitry most likely uses something other than 27V internally, and it might not be able to maintain that. First thing to look at is capacitors in the power control area. Also, did you measure the PSU output under load (i.e., inside the speakers while turned on)?
