Re: Dead but clicking Hanns-G HC194D?

Re: Dead but clicking Hanns-G HC194D?

Ok I desoldered the one side of the four jumpers mentioned and I am still getting the same results. The only thing I can add is that I had my test leads clipped onto the output pins for the 12v and...

Re: Dead but clicking Hanns-G HC194D?
