Does anyone know of a common fault with the Matsui 28wn where there
is a standby light but will not power up. It makes several sounds
(rumbles) through the speakers when an attempt to switch on is made
but then returns to standby. I cannot see any obvious blown caps or
DJ's and really don't want to do a blanket change of the power supply
components as i'm not sure this is the root of the problem. Any help
would be most appreciated.

unfortunately, this sort of problem is rarely easy to put down to
visibly defective components. In fact on every set with this sort of
symptom i have worked on, the caps (and many other components for that
matter)all *looked* Ok but when tested had high ESR, etc.

You will need to check the HOT and measure the output voltage rails
from the power supply to check all is in spec.
Set could be in protect mode due to shorted HOT, Vertical...who knows?

good luck
Ben

Thanks for info.
