I recently got a Pace rng 110 HD set top box from my cable provider to hook up to my Sanyo DP47460 HDTV. No luck! Hooked up using an HDMI cable and I get a blank screen. Using a regular HDMI input jack the tv displayed the message for me to hook up to HDMI input # 1 because the tv was receiving a DVI signal and the input # 1 jack is a combo HDMI input and DVI input jack. But hooking into that jack still no picture. I have an aftermarket DVDR that hooks up to the TV using an HDMI cord with no problem. Also, a blue ray player hooks up with an HDMI cable no problem. I have removed all other cables except the HD set top box from the tv and that didn't help.
I hooked up the HD set top box to another hdtv and it works ok. I had the cable guy out to tell me what I was doing wrong and he says that it is a problem with the HDTV and he has no idea how to fix it.
Any ideas why the box won't work with my tv?

I would say it's a HDMI handshake problem, and you can either try another STB from your Cable company or use component cables. Or you could spend money on a gadget that supposedly fixes HDMI handshake problems (I believe Dr HDMI is one of them). Since your BD player works with a HDMI connection to the tv, the problem is obviously not solely the tv.

Just use component. You'll still get 1080.

Or hook the problematic Pace box to another TV. Verify the video output (resolution) setting(s) in the Pace box.
Some TV's will not accept a 480i input via HDMI.
Set the Pace box to 1080i only output and move to the TV in question.

If you have the TV connected to the Internet (either Ethernet or WiFi), check if there is a software update available. Sometimes manufacturers will release new software to handle HDMI handshake issues.

Also, turn off HDMI-CEC, at least for the port you are using for Cable. I have seen CEC implicated in incompatibilities often enough that it seems best to turn it off unless you are connecting a device that recognizes CEC signals over HDMI.
