I bought the Sony 720P DVD player and an HDMI cable and hooked it up to my Mitsubishi WD52525. The HDMI output light never lit up and the screen was blank when I selected the MONLINK input. I checked all the settings on the DVD player and still nothing. I was just abut to call Sony when I remembered my neighbor bought a new Fujitsu Plasma. Hooked up my player with MY cable and it worked great. Went back home and tried again but no luck.
Then I thought it must be the TV so I took the cable and connected my HD cable box to it via HDMI. THAT worked so the TV seems to be ok as well.
