Re: LG 42PQ3000 No longer powering on?!

Guys I have a similar issue with the same tv. Just constantly clicking with the red light flashing but never switching on. sometimes three, sometimes 15 clicks then shuts down with red light going off. It never goes blue. I am looking for a copy of the service manual if anybody can provide it.
Also. With multimeter should I be able to get readings to the outgoing DC connecters when it is shut down. Currently I get nothing apart from main incoming power connection.
Anyway thanks in advance, any help greatly appreciated.
