Default help with toshiba hdtv and comcast cable box

hello,

please let me apologize in advance for being so clueless.

i just got a toshiba hi def lcd tv model # 19AV00U.

i am trying to connect it to a motorola comcast cable hdtv compatible box. there is no dvd player/vcr involved. just the tv and cable box.

the cable coming out of the wall is connected to "cable in" on the back of the motorola box. i have another cable going from the box "to tv/vcr" to the back of the tv "ant/cable".

nothing happens when i turn on the tv and put it to channel 4 (or 3, for that matter). all i get is snow.

i have another hdtv with a dvd player & vhs that i managed to hook up correctly with the same cable box.

if anyone can please tell me where i am going wrong, i would really appreciate it.

You need to get either an HDMI or component (red/green/blue) cable. Get rid of whatever cable you are now using from the HD box to the tv if it isn't one of the above. Technically, your tv will come on using the analog cable you have now if you press the input or source button on your tv remote till TV/VCR input comes up on the screen, but it won't be HD without HDMI or Component cables.

If you use the component, get one with the five cable bundle as you will need the additional red/white for sound from the cable box to the tv in addition to the r/g/b. If you get an HDMI, it does both, video and audio.

Plug the HDMI OR component cable into the cable box, plug whichever of the above cables you have bought into HDMI 1 OR Component 1 on the tv.

Turn on the cable box, turn on the tv, press the input selecter button on your tv's remote till the appropriate input comes up on the screen. That is whichever input you plugged the cable box into. It will work.

There is no channel 3 or 4, it's an input.

Exclamation having trouble

I am trying this fix that was posted, however, when I turn off the cable box, no matter how I press the menu button on my cable box remote I don't get a white screen. My remote is a Charter Communications remote, not actually a factory motorola remote specific to the box - does that matter? The green screen is about to drive me crazy!

I'm kinda confused about what it is that you want...

Does your TV work with the hookup described in this post?

Also, I never turn off my cable box, just the TV. Maybe that is the answer.

You should have the RG6 cable connected from the cable outlet to the back of the STB, and then HDMI from the STB to the TV. Is this what you have?
