I have had a Samsung HLR5667W for just over 2 years and have been running almost everything through componet cables. I recently wanted to go to HDMI but when I plugged in the HDMI cable to the port on back of the tv I get nothing. I have tried 3 different HDMI cables all with no luck. I have a smaller tv that uses HDMI and everything I plugged in worked. IS there some kind of issue with the HDMI port?? Is there a cost evvective way to replace the HDMI port??
