Thanks for your reply, All the measured voltages look good except V2. Please check values of R9 - R11 and soldering of these resistors and U2C pins. R9 l = 0.21v, r = 3.31V R10 l = -4.95V, r = 3.31V R11 l = 0.21V, r = 0.0V by the looks of it all contacts have a little blob of solder flowed on it ......

So this is what happened: Perfectly followed all steps, up to point A. Use 1) attach probe clips to J1 (done) 2) Touch the red clip with your finger. Do you see signal from your finger?
