Re: LG 42PG6010 No Sound - No Picture

I too am new to the forum so hi all..
I arrived herenvia Google as I have the same model of TV which has been slowly deteriorating over a number of months. It has now finally given up the ghost, sound but no picture. After investigation there were several blown caps on the PSU board. Sourced a replacement and fitted it to no avail. Tried flashing firmware via USB which is difficult at best with no picture. Anyhow there is now nothing at all... No picture or sound. Any pointers as to what I should be looking at next would be greatly a...
