No signal/picture through hdmi/component

mbeil315 · 01-04-2013, 03:56 PM

Hi I am new to this forum but figured I would give it a whirl. I have been hard pressed trying to find the answer to this question tried Comcast chat support, telephone, searched google forever. Does anyone know if there is a fix for this or something? Its very frustrating. I am using a Cisco RNG150 cable box. I read somewhere that it could be the handshaking issue between my tv and the box. But I don't know how to access a menu for the box or whatever its very bothersome If anyone could help it would be appreciated thanks

In looking at the box you mentioned, I see it has an HDMI and component outputs (set of three coax outputs)?

Have you tried the component outputs to see if you can get a picture that way? You'll need to disconnect everything from the HDMI output when you do this.

What is the TV you're feeding this to?

I tried that already and there is no picture but there is some sound. It is being fed to a 42" Westinghouse LCD

If it won't work via Component connection either than it is NOT a handshake issue.
Something is broken.

What I'd do:
Try a feed from a pair of rabbit ears, or from a DVD player, and see if you can get a picture. If nothing, then your TV is shot, if you get a picture, then you probably need a new cable box.

Have Comcast walk you through any adjustments they might want you to make to your MENU before sending you a new box.
(I cannot help here because when I had COMCAST I always had a Motorola box.)

Good point. But I have tried that already this is why it is so frustrating because I have a Blu-ray hooked up through HDMI and it works perfectly

Yes it is correct.

I have a Comcast guy coming tomorrow but I have a feeling he wont be able to figure anything out as well as I can.

If you can't get a picture using the component connections either, chances are good it's the cable box. You've already pretty much ruled out the TV by having success with a BD player, using the HDMI connection. Please let us know what happens with the cable guy. Be sure to show him that HDMI works coming from a BD player and just switch the HDMI cable end from the player to your box to show him that it doesn't work.

It's the cable box or else the Comcast feed TO the cable box.

So did the Comcast tech visit get to the root of the poblem. My guess is that he swapped your cable box and all is well.
