Summary of all available PStwo (v12) fixes (including poll - please vote!)
This whole situation about PStwo (v12) fixes for newbies (like me) is quite confusing. So I'm trying to do a little summary of what different kind of fixes there are available for PStwo and how they work. I guess no one wants to have their PStwo laser die, atleast not me. :) I come from Xbox scene and have experience in softmodding and TSOP flashing them. I'm more into software side of things (exploits) though.
!!! It also might be that Sony has fixed their problems with laser in later batches of PStwo. Atleast foundmy.com states that "if your if your PSTWO unit is a 4D model you may not require this [v12 fix]". Also I've heard of people using modchip on v12 w/o anykind of fix and they're having no problems. !!! Anyone know more about this? I've also heard that PStwo's even without modchips have fried.
Correct me if I have wrong info here, because I'm sure there are. :). Thanks for |Pixel|, summ0ne and spedmetal for helping me out with these.
Could anyone explain me how mechanics controller, CD/DVD controller, coils and laser lens are related to each other? How does the power proceed inside PStwo? And what are the different parts that can get broken without fix?
One thing I could recommend before opening your console (which removes warranty) is to burn a DVD-R and DVD-RW movie discs and run them on your PStwo for a long time! If there's any stuttering or problems maybe you can get it changed on the shop you bought it because of this. Maybe with a good luck you'll get newer version (batch) of PStwo which has better laser? If those even exist.
- The first fix I believe appeared was The Matrix Teams' (from now on referred as TMT) 1N4148 diode fix which uses 2 diodes to to reduce input signal from CD/DVD controller to ~1.2v. This is similar solution as Romeo mod was for v9/v10 PS2s. This will prevent coils from getting too much voltage. The problem here is that when the laser starts to wear off during time the diode's might reduce the voltage too much to prevent laser reading the discs properly.
- The second fix came also from TMT I believe. It is based on simple PIC 12C508 chip and 1500 Ohm resistor. This fix is based on that if the mechanics controller crashes it will power PStwo off. I think there are no cons in this fix. (Again correct me if I'm wrong).

- Crystal Chips (from now on referred as CC) are also offering v12 fix diode fix PCB. I guess this works the same way as TMT's diode fix. Strange thing i noticed is that it uses 8 diodes instead of TMT's v12 fix which uses only 2 diodes. Hmm...

- gamefreax.de is also selling v12 fix PCB. It guess this works exactly the same way as CC's diode fix. I have no idea who is manufacturer of this PCB. The CC's diode fix PCB looks little nicer though. :)
- gamefreax.de is also offering vanDrunen fix. I have no idea who is manufacturer of this PCB and how this fix works. I'm wondering also that is vanDrunen fix same as "PIC fix (12F675)" which was mentioned in DMS forums. Does anyone know?!

also one funny thing I noticed that they are selling Coolpads which you can put on your ICs and it should cool down the modchip and make it more stable and longer lasting. :) I wonder if the modchips' ICs really heat up that much that there use for this kind of product?

- foundmy.com is also selling v12 fix PCB's. I have no idea how these work, but they've stated at Crystal Chips' forums that "we are doing a different kind of fix than the "matrix fix". I wonder if they meant the diode or PIC 12C508 fix. Does anyone know what kind of fix this is?
- I've also heard about peteroos fix, but I have no info about this one. Does anyone know about this?
- Then there is the summ0ne's fix. It uses two resistors and seems quite simple. It seems to decrease max power on the tracking coil. I don't really know lots about electronics so I fully didn't understand how this works. :)

And about these fixes, like |Pixel| said it's better to be safe than sorry. :) So I guess they are worth using.
nexus6 stated: "fact: no fix is 100% safe (most of them are useless pieces of crap)"... So could you clear up which of these are crap?
Any corrections and additions are welcome!
