Title: PW-1450 PSU - LG 42WVSN3 Plazma
Post by: satelliteone on July 28, 2010,13:17:23

Having a bit of a problem tracking the fault.

Its blowing all fuses soon as the relay click in on power up after a slight delay as it goes full power up mode.

The TV is a LG PDP42WVSN3 the PSU is a PW-1450.

Any one got a schematic on the PSU?

Least then i might be able to trace it back..

thanks in advance
