sony vaio GPU

[koresi]

hello,
I have a sony vaio PCG-6121m with video problems.
The board is

M960_MP_MB
8Layer MBX-224 REV1.1.
1P-009CJ01-8011

I reflowed the gpu -> same problems.
I reballed the gpu but the chip has bended and it couldn't be soldered back.After a while I ordered a new chip (according the schematic 216-0774008,becouse I couldn't find the old chip) but it is smaller than board footprint.
Looked back on schematic and it says that are many GPU options but still don't know what should I order.

if anyone have this board and tell me what GPU is on it....
thanks.

Re: sony vaio GPU

Don't use air wand or torch. just use a fine LF soldering station, reballing station and a fine wick, you are good to go. I'm using chemtronics, hakko and 4 corners reballing station is one of the best.

Re: sony vaio GPU

first I reflowed the chip after I removed and reballed but something gone wrong and the chip bended....Its plane has a little deviation so it couldn't be fitted on board .
bad luck...
