ah yea.. did you confirm your assumption by connecting it to different HDMI ports/ different TV sets / with a different HDMI cable ?
if not, then why are you so sure it's 1.) the PS3 , 2.) the HDMI port and 3.) that it's broken ?
If it's really gone you could try out a component cable (PS2 ones work and are very cheap), as these should produce a similar picture quality especially on smaller TVs.
