Either send it to Sony or buy a new one. Everthing else will not last for very long. I had mine fixed by Sony last September, and it has run perfectly since. However, if I didn't have a launch 60 gig with BC, card slots and 4 usb port, I would've just bought a slim.
My friend has used the re-flow method to fix his, and it worked for about 2 weeks. It fixed it again, using the same method, and it lasted about 1 week. He then went and bought a slim.
What ever you decide, good luck
