Does it work sending it into a Sony Center?
As far as I know they won't repair it, they offer refurbishments for €100 (HD wiped etc), some 3rd party places will re-solder it for a bit less though its never a permanent fix and will probably buy you another year. Hairdryer might buy you another month max, best to buy a new one.
