You have to go into the cable box menu and designate HDMI as your output to your TV. Consult your manual for your box as there are quite a few different ones on the market. If you don't have manual, very easy to find online. Good luck.

It is possible that the cable to your antenna is broken somewhere. You have the right idea to start there.
It is also possible that your TV is looking at CABLE instead of AIR, or visa versa.

My ilo hdtv doesn't have a cable hook up


Going to have to connect (no coax fitting means it is a monitor with no tuner) via one of the rear audio/video inputs with a box that has those outputs on it.

HD is almost always connected in this way.

Will not receive incoming cable signal


You didn't mention how you are getting your cable, but will touch on it briefly. Please clarify if you need more information.

Your cable comes in through the wall, and it should goto a converter box / receiver box. The output of this box then is connected to your TV via either HDMI, component video, audio visual connections (RCA), or perhaps the cable coax connector. Sometimes, the cable box will connect via a DVI port, but those are relatively uncommon. Almost *all* modern cable systems have gone to a digital format, which requires a converter box. There are very few, if any, cable standards that are still analog (which could be tuned by your tv at one time). If unsure, contact your cable company to find out exactly which you have, and if a converter box will be required.

You need to setup your tv to look at whatever input the cable box is using, or tell it to look for a signal on the cable coax connector. Make sure the cable box is on before you try to set it up, or you may waste your valuable time.

Im trying to connect my unit to my tv to record shows and i having trouble doing so please help i am hooking it up wrong


For OTA or CATV signals, you need to daisy chain the coax from the source (antenna for OTA) to the coax input on DVD recorder and then the coax out to the coax input of the TV. If you have a set-top cable box with an incoming CATV signal, it should be connected between the DVD recorder and the TV.

The unit can tune in and record 480i (SD) ATSC (OTA digital), NTSC (OTA analog), analog CATV and digital CATV channels.

A satellite receiver or a non-CATV cable box should get the incoming signal first and then have their composite video output (A/V) connected to the DVD recorder composite video input and then their coax (RF) output (if present) gets connected to the TV. For these, you would record from the IN1 or IN2 (press Select Input) instead of selecting a channel. Then connect the composite video out on the recorder to the TV's composite video in.

Digital signals are either enough to tune in or give no signal. So check that your antenna is correctly oriented for OTA.

Separately, you can connect the video signal when playing DVDs via composite (good signal) out and component out (better signal) out to the TV's matching input. For the component video, the sound is carried on a separate cable. Then set the TV to the input source.

In the case of wanting to watch a VHS tape while taping to a DVD, do not use the Component video source, set the TV to Input 1 (composite).

I hope this helps.

LCD TV IS CONNECTED TO CABLE USING SATELITE. CABLE IS RUN APPROX 150 FT FROM SAT DISH TO TV. RECEPTION IS VERY GRAINY,,,IS IT THE LENGTH OF CABLE? THE CABLE IS 100FT CONNECTED TO 50FT CONNECTED TO TV....


Is the satellite receiver HD or standard?
If it is standard you should hook up the box to the tv via RCA cables (Yellow/Red/White) and this will help with the picture quality.

If it is a HD receiver then hook up the box to the tv using a component video cable and this will drastically change the quality of the picture.

Using a coax cable to attach from the box to the tv essentially is connecting an analog signal to the tv and this will produce a lower quality picture...

Good Luck!!

Onkyo TX SR 606 -- Connection Issues with Cable/ Dig Coax Audio


1. Video-out to TV: You should be able to connect the receiver to the TV with any / all of the available video modes.
However, if you don't have the HDMI connection, then the Video-In on the TV would have to be switched back-n-forth between Composite / S-Video, depending on how each device is connected to the receiver. [If the TV has 'auto-sensing' Video-In then it should automatically detect the incoming signal from the receiver whether S-Video or Composite or Component.]

2. Audio-Input to receiver: As the receiver provides only two Coax-Inputs, you would have to first assign Coax-1 to DVD and Coax-2 to Cable. Then connect the coax cables accordingly; that should do the trick and allow you to hear the cable sound over coax.
If you still have a problem then check the 'Input mode' setting; leaving it on Coax-1/2 (Auto) would be the better option. This is on pg. 50 of my manual "Specifying the Digital Signal Format".

Don't worry about sending the TV audio to the Panasonic. Just send a digital audio signal from the cable box to the Panasonic.

DVD - Panasonic connected via HDMI
TV - Panasonic connected via HDI
cable connected to cable box and TV. But you will not really be using the cable connection to the TV (TV Tuner) since you will want HD feed from cable box through HDMI input on TV.

You aren't concerned about feeding the TV speakers because your audio will always come from the home theatre.

Note that some components don't feed audio through HDMI, in which case you will need to use optical digital audio.

Cable box HDMI connection probelm


This is from the Yamaha user guide:
The analog component video signals (with 480i (NTSC)/576i
(PAL) of resolution only) are converted to the S-video or
composite video signals and output at the VIDEO or S VIDEO
MONITOR OUT jacks.
The question is what kind of signals you get from your HD cable box.
