Re: Original IBM EGA card repair thread

I guess the first thing is check all voltages, see if there is a short to confirm your potential tantalum failure hypothesis. If the voltages are OK I'd then be getting as many datasheets for the ICs as I could to see if you can probe the pins for sticking reset or using a logic analyzer (or better, …

Re: New Build, dodgy video cards

It’s more likely that at idle or basic 2D tasks, the strain on the voltage rails is minimal, and the weak or failing capacitors aren’t particularly required for stable voltage rails. Add some load into the mix and the bad caps will be causing voltage ripple and thus instability.
