Connecting Nexus 10 to Panasonic TV

[Secondtenor]

I am trying to connect my Nexus 10 to my Panasonic TV (model TX-L22X20B) to watch downloaded videos. According to Nexus handbook an HDMI connection will work. I have tried connecting with a HDMI/microHDMI cable but I just get a blank screen on the TV. A friend tried on his Samsung TV and it worked perfectly. Is my TV too old for this technology or is there something I can do to make it work?
