Anyone remember what models are and aren't booby trapped?
They every come up with a solution for fried coils?

I thought there was a solution
you are talking about chipped consoles burning out yeah?

v9-v12 all have laser issue.
Its not just chipped consoles, it can happen with movies on DVDR etc - which is likely why they got sued over it.
Apparently good media doesnt have the issue - I have had several v12 consoles with the PIC fix that powers the console down if the problem happens and its never shut down on me with good TY media.
There are various fixes on the internets.

Yeah, but moded consoles could burn lasers even with original games in perfect condition. It almost happened to me, luckily PIC-fix shut off my console.

As per these posts, its not the modchip but the media. But its not like I have done any research on the matter - but @l_oliveira is knowledgeable on such matters.

He also mentioned that the problem is also with modchips as well, and I have to agree with him. The MECHACON does control the current going to the laser, so the problem begins whenever the MECHACON crashes (i.e. SCPH-70000, before SONY fixed that).
Given that the MECHACON is actually a SONY MCU, it can crash due to improper patching by modchips (which is essentially, bus contention).
It's not known whether any of the updates that SONY applies to consoles sent for repair, actually help with the laser's lifespan. Some models do have their tray settings adjusted, to unseize them.

He didn't mention modchips on that thread.
TriMesh did, but he said he's seen it on unmodified units but seems more common on modded units - which you would expect, poor burns are going to be far more likely to be poor than the bad luck of a pressed disc with a scratch in the right place etc.
Basically to have most chance of triggering the issue, you have to have a modchip installed. Which is why I assumed they went hand in hand. Not the modchip itself causing the issue, but the modchip giving you the position to trigger it with poor burns. If it's just bus contention, that happens with all models as thats how the modchip has to work. But the laser issue only appears in v9-12.
Also, the way i understood the chips work, they do their patching and that's it. There is no continuous data being sent while a game is running. So if the chips data was the issue, it would happen immediately and not while a game is running. The only streaming data when a game is running is from the disc?
Like I said, I have not done any research other than my own experience and stuff I've read, but I've installed the pic fix and never had the console trigger it on a v12, but I've only ever used good media and good writers for the best quality burns with the least errors. Which seems to match up with what was said in that thread.

Discs with incorrect error correction data (that can be generated by bad writers or be caused by low quality media) may cause the mechacon to crash. So a burnt DVD Video disc made with a bad media or with a bad writer can surely blow a PS2. You indeed don't need a modchip to cause it to burn. A modchip can make burning the coils a lot easier, though.
The thing is purposely designed to break that way.
Seems like they took the idea from Yamaha, which in 1996-1997 had problems with frying the lens coils on their CD recorders due to firmware bugs (recorder kept a strong alternating current flowing through the coils after a written disc was ejected).

directly? - as in the modchip directly crashes the mechcon
or indirectly? - modchip allows the use of poorer media and therefore leads to more chance of crash happening.
My understanding was the latter.
To clarify though:

The latter.
It doesn't take a modchip for the MECHACON to overcompensate in voltage and burn up the coils. Badly scratched optical media can have the same effect. Of course, with a mod-chip, you're typically utilizing much more burned media than pressed discs.
The V9, (very few) V10, (SCPH-5xxxx) and V12 (SCPH-7000x) fall victim to this. I personally recommend the PIC fix that monitors the voltage on that rail. Once it spikes, the PIC shuts the PS2 down.
If you want to avoid this problem all together. Taiyo Yuden and/or Verbatim AZO silvers will make your system quite happy.
Nevermind the 1/4W resistors in parallel on the focus and tracking coils. That's not really effective, and only hurts the performance of the laser, IMHO.
Remarkable, I've been a member of this forum for 3 years, and this is my 10th post.
