You get anything on an external display? Is this the Intel GMA or nVidia 9300 model?

hi, i would advice you to strip down the laptop. look for the Graphic Chip and use a hot air gun and apply heat for about a min.. then apply good thermal paste and try again.. Problem can be sloved !good luck!

Heat - 230 Degrees

It is definitely a motherboard problem, just wondering if someone else had dealt with something similar.

I checked many voltages and they are ok ( 5v, 3v, 1.8v, 1.5v, CPU_core, VGA_core)

I will try with reflow of intel chipset (ac82gl40) which is VGA also.
Does someone know does they die more often or just need reflow????
