TV turns off when FIOS STB is turned on

Just bought new Samsung PN58C8000 3D plasma 58' TV. I'm using the older FIOS receiver box. When I power on the receiver, the TV turns off. I doubt its the TV, because I've tested it with DVD player, and it works just fine. Not a remote issue either, bc I notice it while manually powering On both units too. The TV will show a channel (with working image of the programming) for 1 second before Powering the TV off on its own. It COULD be the HDMI cable (didn't try recommended 1.4x cable - instead tried just a regular cable). OR, its COULD be that this FIOS box is old, and maybe not compatible with this new TV. Either way, TV turns off still... please give advice.

tampadog70,

Try turning off the Anynet+ option in the TV.

It's available in the MENU and by pressing the TOOLS button.

Does that help?

Anynet was already off when trying it. I have everything plugged into a Monster Power HTS1600 surge protector unit. Do you think that could have something to do with it? As far as power level or something to that effect?
