  Wow, thanks! I didn't think those chips were still available, amazing!

  One fly in the ointment is shipping to UK is $38.95 on top of $56.02 for the chip = $94.97. I have emailed them as I think posting one chip should be less money!

  Also, can anyone help me confirm my chip is at fault? Any readings from a working chip would be much appreciated, just to be sure it is not an ancillary component that is pulling those 3 lines low.

  Thanks!
