PS2 Gone Kaput already??

[skykid]

Hi,

I had baught my second PS2 this time with a Matrix Infinity ModChip in July, been playing a lot of Backed-up games on it, and now it seems it won't play a few backed up CD-R based games.

Right it plays Originals...straight away...and the same goes for backed up DVD-R's and some Backed up CD-R's, it tries to load the back-up and then goes back to the Browser screen with a purple disc visable, i don't get the Dis Read Error message

And another thing i tried to run this CD/DVD Lens Cleaner from a Company from Blaze, but that wouldn't run either it just goes back to the browser.

The modchip allows you to skip the boot screen by holding on Reset at Power-Up, but that just leaves me with a black screen.

I'm not sure which version my PS2 is but its SCPH-50003 with DVD Player 3.00E so which version is that and is its laser any reliable (if there is such thing), but having said that my V3 PS2 works fine apart from it doesn't play DVD Movie Back-ups.

So Do any of you guys know what the problem is? I can't look to see as it is under warranty from whitedog.co.uk, but is it that serious to go through warrenty?

And the media i was using are Philips CD R80 52x, and for DVD's Ritek RiData 4x DVD-R, could it be the media?
