HP 430(M/B No: RC6f32064jh1) no display

[Hasith]

Hi,

Have a RC6f32064jh1 board(HP 430)
It is powering on(Fan working).
All coils showing power except VGFX Coil
No display

No any short in any coil

Even +VCC_CORE coil showing 1.15V

But no voltage on +VGFX_CORE

When press power button caps lock blinking slowly and continually.

Any idea?

It is normal you have no vgfx core it comes up when there is load on cpu when the cpu is needed. I would try to do clean me region first from your original bios.

Check consumption on dc supply(while turned on) under following conditions:
01.With Ram
02.Without Ram.

If its same, then system is not reading ram and thats why no GFX.
