Few questions about SCPH-70004b

Hi all! First of all, sorry for my english.:(

I got an old PAL playstation 2 slimline model SCPH-70004 (and there is a very little "b" just below the "4"). From what I have read some 70004 are v12 and some - v13. And from the sticky thread its clear, that sony have fixed the laser coils problem for v13.
The version of the mother board is GH-035-63 and here is a picture of it

So do I have a v13 ps2 slim or its v12? Also is it needed to adjust the dvd pot (as posted in the sticky) and how to find out which pot is the dvd and which is the cd? (maybe the one with more resistence?) And do I need to install some other sort of laser fix?

Really big thanks!

Put an image of the other side of the mother board please....

Here u go

sorry for the bad quality, but here in Bulgaria is 01:00 am, its dark and im almost :yawn: :lol:

Thats the v13 version of the SCPH70000 serie so you don´t need any fix.
If you google "Van Drunen-fix" you can se that where you are suposed to solder that fix,On you r board arent these points look at the pictures of the v12 and the v13
The first pic from the right is a v13 (Sony´s own laserfix where you ould put the VanDrunen)between the USB and the RS2004 Ic.
The second pic is v13 (only 2 dots instead of 3 dots.The one you cut for the SlimFix isn´t there!)
The third is the same as the second.

Yea, its good to know. Big thanks! Just in case I increased the dvd pot resistence (from 1068 to 1167), but at least I dont need to install laserfix :)
