Essentially when the pedal is engaged I have no sound, in bypass I get the normal dry signal running through to the amp fine. The LED works so I know power is getting to the board. I have had the occaisional flare of distorted signal when the pedal has been engaged an have played around with the trim pot at all points but have had no luck in getting a proper chorus sound and it's almost always silent. When the distorted signal comes through it only lasts a few seconds then fades out to silence.
This is a sure sign of a short or bad solder connection. Whenever you have intermittent operation, the problem is typically one component shorting out to another component, or a bad solder joint making intermittent contact with something. The solution is to make sure all of your solder joints are good. Here's a couple of quotes from the Simple Debugging page on DIY Stompboxes which I've found helpful in the past:
If you are desperate, you can gently! twist the board to see if you have bad solder connections. Sometimes the circuit will spring to life because of a bad solder joint. Twisting the board can alert you to this.
If you are testing the board in the enclosure and it worked while it was out of the box, look for any place the enclosure or a pot might be touching the board or a wire and grounding out the circuit.
Your soldering does not look very even. Some joints are starved like Stephen said, many other are misshapen like they weren't hot enough. Make sure your soldering iron tip is clean shiny and hot. Also, use some acetone or alcohol and an old toothbrush and scrub the pcb to clean up all of the flux and solder residue; that stuff can conduct sometimes.
