You can replace 216-0810084 with 216-0810005 but it requires soldering in a resistor that I have to look up since I have not done this in over a year. Either way all of those GPUs you will find are either someone else's shit stock, fake, or reballed.

The 216-809000 used to be available with a lesser fake/bs/reballed crap rate. I actually have a spool here I will never use. Send me your address and I'll send you a few for free.

I have soldered a 216-810005 that I found here and voltages are ok, I just need to figure out that resistor you mentioned, almost done!

At the moment I don't have LCD_BKLT_EN. Help please!! I know this signal is given by GMUX

 

[larossmann]

Does it recognize the screen? That comes first before LCD_BKLT_EN. Is LCD_PWR_EN present on U9000 pin 1?

Nope, 0.012v. What is required for GMUX for this? I don't know exactly how it works. LVDS_DDC_DATA is 3.3v, pullup resistor is OK

SOLVED!!!

2 resistors missing around GPU, and soldered the resistor needed to detect 1GB Samsung VRAM

This is my succesfull board repair anthem, and I dance to it:

Now horizontal lines and a bit red screen. I've seen many people with this... Fuck this shit...
