I get no picture when I connect the set box HDMI cable to the TV

I assume that you enabled hdmi ports within settings.
I would connect box to another TV and within settings in box make sure that box outputs either 720p or 1080i.
Your TV doesn't accepts 1080p .

Hello, You probably hit the input button by mistake. If your using cable TV your input setting will depend on how the TV is connected. If your using an HDMI cable check to see what number HDMI the cable is plugging into on the back of your tv and then set the input button to the same port number. If your tv is connected with RCA cables (red,blue,green) Then hit the input to AV.

There might be a setting on your cable box for audio output. Use the cable remote and look in the audio section of the settings menu and select HDMI output. Mine is under Audio Digital Output in the Audio/Video menu.

Hi, Your set top box (PVR) is running on channel 3 or 4. Go to menu and sellect a source TV, DVD
Note: Do not connect more than 1 set of cables to tv or you may damage something.
TV > box connect RCA cable or HDMI not both.
Set top box > connect RCA or HDMI Not both.
audio devices > TV connect RCA or HDMI not both.
Good luck.

Is your cable box HD? It would be best for your tv. You can hook up a couple of ways depending on your receiver and tv in/out capabilities. You will always get best picture if you go directly from your cable box out to tv in. You should have capabilty to go HDMI out and perhaps Component out on your cable box. If you can't get hd receiver from cable company. Anyway, if you use HDMI, hook to HDMI out on receiver to HDMI in on tv. HDMI provides audio and video. You can also go componenet(red, blue, green) out from recevier to in on tv. I personally feel component gives you better picture but , doesn't carry audio. For that you need to get audio using either digital optical or, composite cables. You may have to set your HD on receiver through cable boxes menu. The last option is using composite cables(last choice, poorest picture and sound) yellow(video) and red, white(audio)

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

The cable box needs to be set to send different signals when using hd tv and standard tv. Usually a good setting would be 720p in hd and 480p in standard. The tv is working fine it is the cable box sending the signal. If you have another hdmi source such as a dvd player you may hook that up to show the tv is working just fine.

HI

The resolution is only set by the sending unit, in your case the cable box. You need to change this to at least 720P something the your TV can handle.

Now once you have down this, to try and solve your HDMI problem I suggest you do the following.

Switch-off your cable box and the TV set, unhook the HDMI cable.

Now reinsert it carefully to make sure it connects properly on both sides.

Now first switch on your TV and set the input to Video 6 ( your HDMI channel )

Now wait for 30 secs. Switching on your cable box.

Do not press anything and check if your picture now stays on without shut-down.

if the menu and other startup screens on the cable box is not flickering, but the normal picture you might have a HDMI conflict with your TV set.

O, you cannot change the input types.

Hope this helps!

the tv has a configaration that conveys the sets focus on both audio and video performance. full hd resolution of 1920-1080 pixels.
hdmi inputs allow connection of the generation of 1080p sources for the systems which offer 1080p outputs

With an HDMI cable connected, the cable box determines the picture size. The settings on the cable box must be changed in order for you to get the correct picture size. I have some experience with Motorola cable boxes; usually to access the settings you turn the box OFF and then press the menu or settings button on the box to bring up the display menu. Hope this helps!
