You uploaded the wrong BIOS. The SPI ROM you need to backup/flash is U31. File size is 4MB.

Dear techtiger, i too faced this missing gfx core issue on this same mb. I tried all the dumps avlbl at badcaps and some other dumps sourced from net. But unfortunately none worked. The only bios which worked is HP official update. You need to carefully extract your 4mb bios from that update file with hex editor. If you face difficulty doing that then let me know. I'll extract it for you.

PS:You will need to use HP bcu utility and dmitolls to fix the serial no etc with hp official bios.

Re: DA0R62MB6E0 REV: E +VCC GFX Missing

your problem has nothing to do with the bios
the IC PU17 has all the voltages necessary for it to work
the problem is the IC PU17 that is bad or has a short to the output
or either of the two mosfets

Re: DA0R62MB6E0 REV: E +VCC GFX Missing

PYRY thanks for the reply i have test the 2 Mosfets they are good ,after the MAiIN Bios flash last option PC17 but i will wait
