A1286 820-2915-A image problems

[hgoncalves]

Hi,

I have a macbook A1286 820-2915-A with vertical stripes on the screen and a grey image, internal and external.

After disabling the GPU with medusa, and removing R8900, the mac keeps rebooting and don''t power on.

Is it CPU?

Can you help?

R8900, why?
R8904/11 are the resistors from power rails...

My mistake.

Now, with R8900 resoldered again, it is still rebooting. I think I have a corrupetd BIOS now (medusa is asking if Mac ROM is empty, but can read some information, and says that the stored BIOS is identical).

Do you have a CLEAN ME for this model please?

Youy must do again Medusa mod on the BIOS.
R8904/11 must be removed BEFORE applying power.

Hi,

It worked, but now on the loading bar, the Mac stops before ending.

Any idea?

Test in safe mode.

Try known good BIOS (clean ME).
