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.
