Disc Read Error

[Afterlife]

I am suddenly getting a DRE out of nowhere, one day it works now one day it dont. I cant read a single thing games nor movies.

You guys are the only people I know who might be able to help me out.
After researching the problem I found a few fixes one of which ive tested.

I cleaned the eye with alcohol on a qtip to clean it and this did not fix it. I read that it might be a voltage to the lazer problem. But i dont know how to fix this and dont wana mess around if there are other probably fixes.

I took it to the guy who put my chip in (Magic 3.1) and he said he cant find anything wrong with it, tho he didnt do any tests just checked the wiring on the chip I guess so at least hes covered.

I also heard it could be chip related where you change the W point to the alternate one?(no idea what this means)

So if anyone knows of a way i can fix this im all ears cos my summer has started off to a bad start.

thanks in advance
