Re: Re[2]: black widow pcb problem no play no picture clock working

Hi Alex,

Can you elaborate a little bit more on this for those of us still going up
the learning curve? :)
What is glue-logic?
When you break out the logic analyzer, can you give some general information
about your troubleshooting procedure, what make and model you prefer to use
and what you're looking for? Just the real basics to bring some of us up to
speed.

Thanks!

Matt
