2914 gpu 0005

[G.Beard]

Got a 17" in for GPU replacement. Replaced with the good 1617 chip
It was one that Apple had already done with a DC 14xx chip.

Now just get a grey screen. No boot menu, nothing.

Checked for anything knocked off the board, all looks fine.
Checked the balls, good from what I can see.
Checked VRAM balls. All look fine.

What could I have fucked up here?

I have not had any issue with the 2915 boards but I'm not so lucky with the 17" boards. Balls all look good but I'm ballings up a lot of the 2914 boards.

Yeah fuck the boards that were already done by Apple. Could be bad VRAM but I have had too much failure with the ones that were already done.

Oh... Turns out I fucked up the screen cable and also just needed to run the profile again.

Does anyone else have to tap the GPU a bit to get all the balls to take?
