take a picture(s) of your circuit and jumpers to led, phone jacks and adjustable resistor. If you have jumpers on the bottom of the board take picture of that too. and PM me with these. You will have to upload the pictures and then link back to them in your post ( save the address after upload )and I will try to trouble shoot your components and circuit connections. If the components are not identifiable on the picture please describe the specification for it (like: CAP 22uF 50V).
