No picture when connected to cable box with hdmi cable

Likely have a bad cable box. Could cable have bad connection before box also.

I would suggest you verify your cabling. Are you using HDMI cables? Connect a HDMI cable from the TV HDMI 1 to the Cable DVR Box, In the TV setup ,select HDMI 1 as source. If your Cable box does not have HDMI contact the provider for a updated box. With out the Make, Model of Box, Cable? Sat? Make, Model of TV. I don't know the connections?

your output cable is in the back of your t.v. there is a color designated on its hole then you have to buy a a cable in any electronic shop like components cable or hdmi cable try to read the back panel of your tv

Connect the TV directly to cable box to make sure the TV and cable box are ok. If you have picture then the receiver is no good. Some Denons have problem with HDMI board (digital unit).

I connected a fiber optic cable from the cable box to the receiver and connected an hdmi cable from the cable box to the tv.

1. Hello boss, here is d way to make best use of it.
   step 1.Make sure ur LCD or Plasma HDTV has an HDMI port. Hopfuly u bought 1 with it, if not, you may be stuck using component cables. Not bad, but not he best. Component cables change d digital signal frm the cable box into an analog signal. This conversion allows for signal degradation. U want to keep the digital signal transmitted frm the cable company 2 go directly into ur HDTV. An HDMI cable will provide u wid this capability n with d clearest picture.
   2. Make sure ur cable box has an HDMI port. Most cable companies do not offer a cable box with an HDMI port on the initial install. You may need to upgrade by calling your cable company and asking if they have a cable box wid HDMI capability. Ask them 2 send u 1.
   3.Purchase an HDMI cable. TIP - The longer d distance between the cable box n d HDTV, the better d quality HDMI cable. This is due to degradation of d digital signal over long distances, wiz could result in a poor quality picture. ne distance over sixteen feet should be compensated 4 by using a heavier gauge HDMI cable. Oh yea, don't get taken by buying the most expensive cables. From what I have read, companies are cashing in on this relatively new technology. I bought my "gold-plated" HDMI cables from an Ebay Store, "eforcity" for about a quarter of the price found at the local electronic store. Connect one end of your HDMI cable into the HDMI (out) port on the back of your cable box and connect the other end to the HDMI (in) port on the back of your HDTV.55
   Read the instructions that came with ur new HDMI compatible cable box. These instructions will explain the download process the cable box needs to go through before use and the Setup Wizard that will program the cable box to send the correct picture format to your HDTV. If u did not get instructions, u can get them at the cable box manufacturers website. Scientific Atlanta's website: http://www.scientificatlanta.com/products/consumers/new_cableboxes.ht64. Adjust video, audio, and screen settings to ur liking. The explanation for these settings can be found in ur HDTV's user's manual.75.Push ur "source" button on ur remote control or HDTV n select HDMI. Tune to a Hi-Def channel. Most Hi-Def channels r in the 700 channel range. Check cable company listings 4 d specific channels.
   
2. Have a nice time!!
   

Yes I got the problem fixed. When we got the new cable box you have to call in to Time Warner cable and they have to program the new box.

Thanks for the reply

Connect the HDMI outputs on your various components to the HDMI inputs on your receiver. Connect the HDMI output on the receiver to the input on your TV. HDMI incorporates digital audio, so no need to buy optical audio cables. If your receiver does not have HDMI inputs for all your components, you will need to make a choice. HDMI = Best, component video + optical audio = second best, S-video+ optical audio = third best

Cable boxes have notoriously flaky HDMI outputs. I have seen No pic and no sound with their HDMI outputs as well as a host of other problems. You can try getting the cable box replaced; unfortunately I have seen multiple cable box replacements not fix the problem. The best solution is to leave the component cables connected; you're not losing hardly any resolution/picture quality by using the component instead of the HDMI. Solution #2: switch to a satellite provider. I rarely see HDMI problems with satellite boxes

It won't work as the DAv can only output to HDMI by bringing singal into the HDMI input.

why wouldn't you send it directly to the TV and Audio to the DAV? I sounds like you don't have an HD box anyway (otherwise why would you use an analogue S-video cable vs component or HDMI). Unless there is a distance issue then go to the TV.
