(laptop display was coming like this before my chip level operation.)


the very first think about my this post on RE-FLOW BGA CHIP is, you don't need a costly BGA REWORK STATION MACHINE to fix the problem all time .
that can be possible to fix without special machine
just you need a simple smd hot air gun(smd rework station) or a heat blower.

first open laptop carefully and take it'a motherboard on your working desk,
and start flow my steps

normally warm-up motherboard slowly

you can choose a good quality liquid flux as per your requirement



Reinstall CPU and heat-sink



Now your laptop motherboard ready to working again.
so check it out.....




that all step i flowed to fix a hp DV 2000 nvidia BGA problem, without using a costly BGA rework station :))
