Ps2 Not working!

[TATTY]

Can anybody please help me?
I got home from work 2nite wanting to play my newly bought ps2 copied games.
None of these would work not even any of the ones which I already had tried.
I cannot even get my originals to work.
I've tried dvd rom and cd rom originals and even dvd movies to no avail.
I can here my laser clicking and I can see the white disk spinning.
I can't however here the usual high pitch whizzing sound when the disks try to load.
I can't take the unit back as I have invalidated my warranty fitting the no solder mod chip, which worked fine until now.
Please help,do you know any ps2 repairers around the nottingham area in Uk?
