HELP! MY PS2 has died!

[wildthing]

Dunno if any of you remember my post from a couple of week ago,my PS2 refused to boot disks from reset instead it kept going to the browser screen.This problems now gotten worse, it only boots PS1 & PS2 originals 2 times out of 3 now and a brand new AR2 disk I bought won't boot at all.Before booting originals the laser seems to struggle reading the disks, it makes all sorts of wierd clicking noises.I've been informed by a local MOD chip fitter that it looks like a faulty chip installation but I thought it more likely a problem with the laser(what with it struggling to read originals).The thing is my machine is supposed to be guaranteed but the firm I ordered it from is refusing to answer my E-Mail or phone calls(If they dont answer within the next 5 days I'll post their web address so nobody else gets stung by them).Just wondering anybodys views on whether this is more likely the chip (NEO 2.2) or the laser as this local fitter won't have anything to do with a laser problem & I'll have to send it to a specialist for repair.
