2011 17" 820-2914 Board. Boots, no video. Usual Issue?

I haven't seen this type of failure with the usual video chip failure of this generation. Normally I'll get distorted video or a non-posting or non-booting situation. Is this the video chip failing or should I be looking for something else? Not a spill, just came in booting but no video. Tried a test screen, same thing.

Yes, sorry, left that out. SMC_LID is good - 3.4V. PPVCORE_GPU is at 0V. No external video.

10Ω to ground. Seems decent. Not sure exactly what the 17" board should be at but that doesn't seem too far off, if at all.
