V12 Replacement Laser

[BakedGoat]

Well I think I burned my laser. After opening my drive to take out a backup that wouldnt load, I smelled something burning. I was fiddling around with the mainboard and started sniffing around and smelled the same smell on my laser. It doesnt look clouded though, I can still see a b****h reflection. None of my backups or originals load though. Can someone offer me a solution? I've thought about a new laser, but I dont understand the whole PVR and wide/slim laser thing. Could someone explain this to me? Also my lens isnt clouded, so could my laser actually be salvagable?

There are 2 laser types, one is the PVR802 ( search the forums) and the other is a SPU 3170. I've attached the two different types. If the console isnt playing anything and is going to the browser, then your laser would be the first point of call.

You haven't mentioned if there is a laser fix, so I am assuming you haven't been inside, which is best if you dont know what you are doing, many ps2 have came to a grizzly end this way.

Changing the laser is not a difficult task however and they can be obtained fairly cheaply off the net ( around 14 GBP last time I looked).

Also you didnt mention if it was pre-modded or if you had it done by a pro, or what discs you are using ( the cheap ones are useless).

You can test the laser coils if you have a multimeter, the points to measure are on this forum if you want to look and you want to be getting a reading of no less than 5.0 ohms on both coils.

Hope this helps.

Thanks for the reply Flying Scotsman! I knew I forgot to include some information. I ordered a Matrix Infinity about 4 months ago, and put it in myself, along with summ0nes fix. I had abolustely no problems at all, until 2 nights ago when I was switching games and noticed the game I wanted to play wouldnt boot. I opened the tray, and smelled smoke. So I took apart the PS2 and noticed that my summ0ne fix broke, and only 1 wire was attached to a 303 resistor. So I guess my laser burnt because my fix wasnt exactly, working.

Is there an advantage to getting a PVR laser as opposed to getting an SPU?

*edit* woops, just realized that my PS2 came with a PVR laser. Is there anyway that I could revive this laser?

There is your answer as to why the the laser burned. The loose connection have most likely have touched a ground point, which fried your tracking coils. Or maybe it was loose in the first place, the loose wire never touched ground or any other connection, so it stayed working but unprotected. In this unprotected you were unlucky and had a mechacon crash which in turn burned the coils.

As for which laser to get, you only need to consider the PVR "narrow" lens. Firstly, the SPU "wide" lens are of a lower quality, and I have only ever seen PVR replacement lens for sale. I think your safest bet is buy the whole optical block. It doesn't cost that much more than with just the lens only, and that the tracking motors is on the optical block itself, if thats the main cause of the lens failure.
