I just acquired this Chips F64300 VLB card today, and I was putting it through its paces when it suddenly died. The screen went black.

After having done a little bit of benchmarking for maybe 20-30 minutes, I started running software for fun - Commander Keen followed by Epic Pinball. I saw the Epic Pinball title screen for a couple of seconds, and then the monitor went black.

I noticed a couple of oddities before it happened. They may not be of consequence.

Running Univbe 6.53's vbetest showed a variance in speed for the spinning lines during the framebuffer test. That was odd.
Also of note was that HWinfo reported the card as being on the ISA bus. That... may have just been a bug in hwinfo?

The card had two extra RAM chips in it to bump it to 2MB. I removed them as part of testing after the failure. They are therefore not present in the photos.

My guess is that perhaps that LS245 went bad. I am open to suggestions for how to proceed. I have a scope.

BIOS chip isn't socketed, sadly, in the event something went wrong there.
