All the phat models I owned stopped reading CDs within a year
Mine read discs for almost 15 years before I had to replace the laser.
Did that and it's doing fine.
I think they all have issues, maybe the super slim is the best..idk.
The slim units are bad about the ribbon cable to the laser/lens coming loose and getting caught up in the DVD drive's mechanism.
It's simply stuck in place with some sticky stuff (tape?) and over time it tends to let go.
Yes, the ribbon cable coming loose is what causes a slim to "Eat" or scratch discs badly.
I've had three of these units I found with this problem - Never got any of them to work after the ribbon cable was replaced due to additional electrical damage caused by the cable coming loose and being chewed up.
Phats don't have a ribbon cable like the slims do so it's a non-issue with those models.
