I had a similar problem a few months ago. The buffers were damaged and I replaced them and the ICD2 came back to life. The buffer ICs are U6 and U9 (in my case only U9 was damaged). I replaced them with MM74HC126MTC ICs which I purchased from Mouser at $.35. Cheers ----- Original Message ----- From: "alan smith" To: "Microcontroller discussion list - Public."

Fine pitch smt doesnt bother me at all. Just need to determine the parts to replace, order/sample and get back in business. > > Xiaofan Chen wrote: On 1/2/07, alan smith wrote: > > Working along.....my ICD2 decided not to recognize the device on > > the board.
