I just bought a Panasonic plasma hd tv. I bought a HDMI cable so I can connect it with my Toshiba satellite laptop. I have connected past TVs with the same laptop and everything worked fine(None of which were HDMI all S Video). When I try connect the HDMI with my new TV the TV says that there is no signal. I wanted to know if anyone else has come a cross this and what they did to fix the issue. Thanks in advance the specs on the TV are 1080p 600hz (I am not sure if that helps)
