| Just finished reflowing the nvidia gpu on an HP DV2500 using the jovy.
Just used the standard Jovy leadfree profile and PLENTY of foil tape protecting the plastic components on both sides of motherboard.
Worked perfectly 1st time.
If a reflow doesnt fix it, remove and reball with lead based solder and re-attach with a lead based solder profile.
If that still doesnt work, the chip is duff. Remember to check whether replacement chip has lead or lead free balls and use appropriate profile.
Obviously, if you dont have equipment to reball, you need to go straight to replacement.
