Re: Bang & olufsen tv beovision 7- 40
Hi I took speaker round a friends who has similar set. No sound. I have seen a couple of times speaker on eBay with what sounds like a similar issue. I have replace the power link cable to speaker. I have tried head phone jack this has no sound output either, but I'm under the impression the sound out head phone socket only works when speaker is connected.

Re: usp440m-42lp psu
I measured the wrong resistors. I had the board the wrong way round, as there are 4 of them, I tested the wrong ones as I was rushing yesterday...Leave a comment:

Re: usp440m-42lp psu
