V12 683 replace - wont read!

[MaximusDK]

Hello everyone...

I tryed to install summones fix on a V12 but broke one of the 683 resistor.
found a new SMD resistor from an old powersuply and replaced the broken one... I didnt install the summones, because i didnt want to breake the new resistor. the ps2 read disk when i tryed it but after 2 weeks now i wont boot any PS2 games... only original will boot. when i try to boot a backup copy it just shows a black screen, like its just about to show the Playstation 2 logo. I can hear that its trying to read the disk and then it just stands there... I also installed SlimFix V4 on it and its a Crystal 1.1 modchip i installed.
could someone help with a solution to this... its like the resistor isents right, but should i use a smaller or larger resistor to make i read better?

Check the cables from the modchip to the laserpoints.....its the 3-4 ones near each other....(havent installed a crystal chip but had a similar problem with my Matrix Infinity and that was the reason..)
