Hi,
I'm repairing my flatbed scanner but I can't figure out what the output pin of the 7905 connects to. Here's some snaps: Front: http://img517.imageshack.us/img517/9646/23249045py3.jpg Back: http://img524.imageshack.us/img524/84/13459958xc0.jpg Reverse: http://img524.imageshack.us/img524/7761/30152421ct5.jpg I can see where the input voltage and ground pins lead, but the output pin doesn 't seem to lead anywhere. Is it a layered PCB or am I missing something? It makes sense that the output voltage isn't connected because the scanner does nothing when plugged in; the power LED doesn't even light. -- Alec S. news/alec-synetech/cjb/net |
