what kinda sound you hearing in the background? Is it noise OR a whisper when the pot is set to minimum.....I'm using the same setup without any problem...

Hi, Thanks for your reply. I can hear the music at very low level, it does not alter with the volume pot.
Colin.

CLN if no resistance is recorded then something is direly (is that a word? ) wrong, which obviously is obvious to you.
Whats wrong I dont know. I dont have that board and cant figure out why you have no reading, which means zero power, from the LDRs. No power is getting to them. Do you have a solder blob somewhere shorting ground to positive? Maybe a pick underneath.

Thanks for that, I did check everything but obviously not as close as I should have, I will re-check again and report.
Colin.

Having checked the underside of the board I cant see anything that would cause the problem. This may sound really stupid but I just have to ask, on the diagram for the board I noticed that where the connector blocks sit that all the circuit runs are on the inside except the actual power which appears to be the circuit runs on the outside of the board, if this is true then this would explain why I have no power.Colin.

Why would that explain it? Your pictures, while well taken, dont reveal much.

That would explain it if the outside two connections are not in fact continued through to the inside connections of the board, if you follow me. Colin.
