OT: PS3 Repair

Anyone recommend somewhere to get a PS3 repaired in or around Cardiff. My son's seems to be overheating or something and freezing then switching itself off.

Cheers
Steve

Iv got the exact same problem.
I left it switched off for about 2 weeks, hooverd the vents and its working fine... well has been for a week so far, hasnt switched off but the fan does get loud. If you phone up sony though they will replace it the next day
