820-2850 no image, no chime

[sh33pz]

Hello,



I have an 820-2850 with no image and also doesn't chime.

Using 85w MagSafe official apple charger

If I take the memory out, it will beep and if I connect a mouse, it does light up.

I have tried another display as well to rule out a bad LCD.

No liquid, the board just stopped working.

The only odd thing that did happen was the unit did boot up once with an image and apple loading bar from my USB drive. I only had this happen once while I was swapping around parts turning it off and on.

Wondering if anyone has any ideas?

Thanks

It reports both GPU's the intel and the GT 330M, I am going to assume there is no fix other than disabling the NVIDIA GPU via some hardware mod?

Can HWMonitor be trusted? System total taking 47W, CPU VccSA 7A, GPU Die 236c insane numbers.

It will show correct GPU Die temp only if GPU is in use...
The other values are correct.
