Sony PS3 60GB HDMI failure repair?

[bseivxx]

I also have a 60 gig. Ive had it it for 2 and a half years now with pretty much no problems. The exact same thing happened to me 6 months ago.
I had to switch back to standard A/V cables. From standby mode you hold down the power for 10 seconds it powers on makes a long series of beeps and the lights flash and it resets into standard A/V. Once you can see everything on screen with standard A/V cables, go back to the system settings and switch it back to HDMI mode. I also run my PS3 on my projector using component cables and I've had it do the same thing from component cables. I thought it was the projector, then the ps3 system and then the wires. But now I don't know what causes it. Maybee it just loses sync?
Hope this helps.
