v12 Too many fixes! –
So far I've done two original v12 MI's w/ 560ohm resistors - stress tested for a month so far no problems. I get alot of request to mod slims but have been turning them away because I'm still a little unclear on what fix I should use. I've seen Summ0ne resistor fix, Subzero fix, Comsoft fix, neo fix, diode fix, Crystal pcb, generic pcb... I'm so lost.
On top of that there are now 12.1s and 12.2s and depening on what fix you use you can have problems reading media with these?? Please help, there's like 5 threads and I'm not super technical. I'm pretty confident in my soldering skills so can I just use that 1 560ohm resistor no matter what version v12 I have?
Can someone summarize on how to identify what version v12 you have and the recommended fix for each v12 version out there? If I have to buy those PCB fixes also list where I should buy them. Sorry I haven't really searched. Thanks

use summ0ne's fix and if u want with a pic fix. i haven't tried the sub zero fix so can't say about it.
I believe if the resistors on the ps2 board (where you solder the resistors for the summ0ne fix) say "383" then its a 12.1 and you use a 560Ohm resistor, if the resistors say "683" or you look at it differently like I did and ask what "E89" means (lol) then you should use a 2KOhm resistor and its a V12.2
Hope that helped, I suggest using the Summ0ne fix personally, but do what you want, I hear the Crystal PCB Fix works well, dont know, never tried it. Diodes from what I hear (never used that fix) dont work for shit really, and the Comsoft/Pic fixes are a good idea. But I personally don't want to cut tracks on my PS2s main board.
Solderless Mods and Flip tops are like tampons, every pussy needs one!
u use the 4.7k ohm resistor regardless
as liquid says.. (although slightly wrong) use a 560 ohm for the ones with the 303... and a 2k ohm for the ones that are 683
just read the summ0ne fix and it has a guide there showing how to pick which resistors u use
FYI: 2k ohm == 2000 ohm and 4.7k ohm == 4700ohm
summ0ne fix alone should prevent the lasers from coooking
Questions on random stuff from various threads:
560ohm on tracking for v12.1 boards (303)
2.0kohm on tracking for v12.2 boards (683)
4.7kohm on focus for all boards
^Can someone go to http://mouser.com/ for me and get the direct links to the product pages for each of these resistors? I also need a 100ohm 1/4 watt. Thanks.
So 4.7kohm on focus decreases the max power on the focus coil on the laser lens by half because sometimes the focus coils die after a few weeks of use. But how often does this happen is it rare enough to ignore? Also can decreasing focus limit media compatibility?
I read there's a new SPU3710 lens that doesn't need summ0ne. And doesn't work with
What is GH-035-61 and why doesn't it function with focus protection applied?
Why are some people using 1.8kohm instead 560ohm on tracking?
Reports of fried gh-035-71 boards with summ0ne's fix
Sub-zero advantage over standard summ0ne fix: Increases media compatibility
Please list media that works good with standard summ0ne fix.

people are using 1.8k ohm because its close to 2k..
it does not replace 560.. its for a different mobo all together
If your 1.8K has a low tolerance you could get 2 resistors and put them in series with each other. Their values need to be 470 and 1.5k and they come out to be very close to 2k (should be between 1871-2068 if using 5% tolerance resistors) a 1.8 could be as high as 1890 and as low as 1710. Depends on what you want to do and how flexible the resistor values can be. You can also buy 2k resistors or use a potentimeter and set it right at 2K, but they are expensive and huge. Just have to check them with a dmm to make sure their tolerances are good, heatshrink them and use some 30awg wire to solder to the smd resistors and you're set.
Ok I just found an electronics store close by me. 5cents a resistor
I got 30 of each:
brown grey red gold = 1.8kohm correct?
red black red gold = 2.0kohm correct?
Now that I have the 2.0k I don't need the 1.8k?
