I am in the process of building a Socket 7 PC as a DOS capture source, and I've been having problems getting it to POST. Long story short, I am currently stuck with a non-working SiS6326 PCI card that I need to repair:
I realize the SiS6326 is a POS chipset that really does not require this much attention but it is one of the very few PCI video cards with an S-Video out in my collection and getting it fixed is in my interest.
Anyway, here is the fault I have located on the card on visual inspection:
CB15 is missing and gone - the card apparently joined my collection in this state. If you need proof that this is what is causing my issues:
0d for AWARD is initializing VGA, and the missing component CB15 appears to be in curcuit like this:
Now I need to:
a) Replace it with a suitable rating SMD capacitor (or a ceramic capacitor using the via's just below, as it would be more suitable for my soldering skills..) - and this is where I need advice as to what rating it could be?
b) Just bridge the via right below the capacitor and bypass it completely - what could go wrong?
c) ?
Your suggestions please?
