Verizon upgraded my routers and the new box for my TV has no coaxial cable output. I used to run the cable from the output on the box to my EPIC View 550. What do I need to make the TV work again?

Probably a handshake problem with the cable box. It is common for cable boxes to have HDMI handshake problems. Hook the box up using the component cables and you should be fine

SOURCE: no signal when hooked up with a digital cable box

I had the same problem and had the cable guy out and everything thinking it was my box. I figured it out by myself here is what i did to fix it. I have the vizio 32 inch hooked to an hdmi cable and through the cable box i had the aspect ratio on 1080i and i should have had it on 720p once I switched it I havent had the problem since.

I have similar situation with my TXDS 565 and could not video out of my unit after hooking up the cables properly in and out of the unit for all auxilary modules... I assume that you have tried to place your vid IN from the cable box to your units vid IN and run a vid OUT cable or S cable to your TV. If this doesn't work for you as it did not for me, then you must run your cable direct to the TV vid IN and run your audio out from the TV audio Out back to your reciever as audio IN in the Video I or II ports on the reciever unit. This will give you audio control through the rec. unit.

I suspect that my is damaged and will not function properly; yours may be too,

My unit is about 10 years old and repair is too expensive so I will run it this way until something else fails and I will replace it... probably not Onkyo.,'

Let me know if I clearify any of this.

SOURCE: Problem hooking up DVD player to TV thru my cable box

Chances are you've got your DVD player hooked to OUPUT jacks on the cable box, not inputs. I haven't yet seen a box that takes any kind of an input other than the cable line, but they will have RCA jacks for audio and video outputs on the back. So your cable channels are fine, but the DVD signal is hitting a dead end.

The only solution if your TV doesn't have RCA inputs for video and audio is to get an RF converter (around $10-$20). This takes the A/V signals from your DVD and turns them into a channel 3 or 4 signal that connects to your TV's antenna input.

The converter also has a connector on the back for the cable coming from the cable box, since you'll have to disconnect that from the TV. When the DVD player is off, the cable box signal gets passed to the TV as normal. Turn on the DVD player and the RF converter switches on; put your set on channel 3 or 4 and you'll see your video.

One final thing: The converter will need an AC outlet for its power adapter or power cord, so make sure you have a spare. If you don't already have your TV and DVD player connected to one, this would be a good time to pick up a surge-protector outlet strip. Then not only will you have enough outlets, you'll be protecting your equipment as well.

If this solution has given you what you need, please take a moment to rate it appropriately. And thanks for asking here!

Problem is with your ISP/Cable Company accepting the installation as one with HD clients, which while
not necessarily costing you more, must be specified to the cable box by your installer.

Make the call.
