I have ordered some off ebay from China, we'll see how that goes... If anyone can point me to any reputable sources then I'll also order from them.

That would be it, (F#@k) don't know how I missed the obvious differences in the block diagrams, I was focusing on all the calculations and tables being the same and missed it. Are there any known good sources for the C version that don't have a high minimum order quantity?

PM_ALL_GPU_PGOOD is now 2.7V rather than the 0V before hand but now VID0 is 0.85V, VID1 IS 2V rather than 3.3V, VID2 is still 3.3V

0.1V on L8920, not exactly close to the 0.75-0.9V in the schematic.

Finally got the replacement ISL6263 in, fitted it and I am now getting PM_ALL_GPU_PGOOD 3.3V but I still don't get display or external display signal - I think the soldering is all good - it's been a while since I've done anything with the hot air. I'm assuming everything should be ok because...

Sorry should have mentioned the board was replaced by Apple, was around18-24 months ago. GPUVCORE_EN is 3.3V R8911 and trace to pin 22 check out. Will need to check 14/16 later, left my pointly probes at work, can't get in with the ones I have to hand. Will update once I've checkout out those...

I am trying to fix my significant others Macbook Pro Early 2011, water was split on the keyboard and fun ensued! The display doesn't turn on, checked with torch, doesn't work on external display. Otherwise it seems to be working ok, boots up, hitting the esc key gets the bonk noise, can shut it...
