There is just one hdmi port but when we make the connection there is black screen that says regime not found. Do I need to ajust some settings manualy or are they just not compatible? Model of tv is Samsung PS-42C62H type no. LI42C6
Have you tried resetting the PS3? Sometimes it doesn't know to use the HDMI port otherwise, or if you used the HDMI port previously, it might be trying to operate at a bad resolution or refresh rate. Either way, resetting the PS3 should fix it unless they just absolutely refuse to communicate.
