I have a ps3 and when I hooked up the hdmi to my old sanyo tv the hdmi wouldn't work. I took the system over to my friends who has a samsung hdtv and it worked.

I just came across a 360 with hdmi and it worked with no problem.
I don't know if the ps3 hdmi is broken or what. Why would the 360 hdmi work on the sanyo but not the ps3?

I test after each firmware still no luck. I held the power until I hear the beeps tried different cables no luck. I am stumped

Any help.
