Started working on board#3 and I get nothing. No signs of life during self test or otherwise.
Started by metering RAM buss and AVG socket. About to pull socket and noticed a scratch mark across the middle. Putting a meter to it show short between tei traces and 5v rail as well. Ran a pointed edge across the traces snd thought it was clear but still shorted. Started pulling chips on the circuit and testing. Finally cleaed the circuits and still grounded.
Went back to the original trace scrape and had to run an sharp edge literally cutting into the board followed by the solder iron tip to get the short to clear. Usually I can clear them with the hakko snd the tip of my meter but not this one. It also took several passes.
