One of my kids tripped over the power cord one too many times and the connector soldered to the dc board came loose. This morning I decided to solder it back. I've done this before for a neighbor so I wasn't expecting any problems. Well, now I can't get the computer to start up, it will charge the battery, I have power to the keyboard (the cap and num lock lights), there is no startup sound, but if I plug ear buds in the back I hear a faint blip when I hit the start button.
I have reseated the processor
reset the pram
tried to start with the keyboard and pram battery unplugged, no battery,power cord only
I have a good power supply
pram battery(aprox 6vt)
the computer worked flawlessly before I re-soldered the three pins that came loose and that was it, I can't understand what might have happened...
It's possible that something else happened to the computer when I had it apart, but I think it must be in the dc/sound card -I have a Lombard that I took apart to see the dc card and I can trace some of the circuts on both as the same - does anyone know how to troubleshoot a sound card? Any ideas?
