Hello, I realize this is a bit of a necrothread, I'm attempting to follow the troubleshooting steps by John Guion above. There's a lot of parts that mention "checking for locked up signals" - does that simply mean that the pin is stuck high? Or is there more to it that I need to check with a scope? Thanks.
