Sorry, that one sentence should read:

Hello Jacques, I had exactly the same thing happen to me last year when I had built my W1. First I checked all my solder joints, all were OK. Then I started checking the continuity of the PCB traces using the schematic. Simple job: if, say, acording to the schematic one side of R4 is connected to one side of C5, just put an ohmmeter across this trace to see if it reads 0 Ohms. That way I discovered my PCB had one hairline crack that was virtually invisible. I just soldered a small wire to bypass this trace and all was well. Hope you find the cause of your problems soon.
