From yesturday my PS3 hdmi port doesn't work i tryed to reset the video output but nothin seem's to work, only a/v cable works but the rezolutions sucks.Any solution can this hdmi port be change?I don't have any warrenty
None of the internals of the PS3 can be changed by the user without a significant degree of skill and research. I wouldn't recommend that as you risk wrecking the console.
hmm... Try connecting both methods to the TV and seeing if you can use the regular connection to specify a HDMI resolution. The system should then be able to toggle to the HDMI connector which should appear if you change the channel.
If this doesn't work you might wanna try calling Sony anyway and seeing if there's anything at all they can offer you. Who knows, they may still replace it for free It's worth a try! You can get the info here.
I just had this same problem not half an hour ago. I was so mad and ready to try and sell my ps3 because it did still work with av cable. I came across a post that said to reset my tv, which is a sony bravia, and I looked the directions on how to do so online. had to wait ten mins while it searched for tv channels but it worked fine afterward. I hope this helps.
