Your plasma tv will display HD content when you connect an HD source (Blu Ray Disk, Sony PS3 / PS4 or Xbox 360, HD Cable Box, HD satellite, etc) via the TV's HDMI1, HDMI2, Component1, Component2 jacks or if you connect a UHF/VHF TV antenna (not cable box, etc.) to the "Ant" connector *and* you're close enough to a broadcaster with HD content to view.
Using any other input will produce only the lesser quality SD video signals. Review the manual - linked below - to help you connect the components you have.
Be sure the 3 video wires are color matched on both ends. Try a different cable. Connect another device like dvd player to that same Component input if it's ok then cable box is the problem. If still B/W then replaced a/v or main board.
In order to get any of the Freesat channels, you need to connect a Satellite dish to your TV. If you have a Sky dish, you simply need to run an extra Cable from the LNB from the dish and connect to your socket on the back of your TV.
In order to get Freeview channels and Analogue channels, you need to connect a aerial to the back of the TV.
There is a menu option for the TV to start straight to the AV input (your Sky HD box). It is Menu > Setup > Other Settings > Power on Preference. Select 'AV' for your TV to start on Sky HD.
Also even if you have your TV to start on TV, when you turn on your Sky HD box, it should automatically switch to the Sky box.
I found that since the Panasonic TH50PZ80U TV has only 2 HDMI ports on the back of the TV, the best solution for me was to use component (red, blue, green) cables to connect the Home Theatre to the TV. I suppose I/you could connect the home theatre to the HDMI port on the front panel, but I don't want cables hanging out the front of the TV (personal preference). Unfortunately, I am no longer able to use the VIERA Link functionality available by connecting all Panasonic components to each other using HDMI cables, but I feel it's a small price to pay for the incredible picture quality acheived by using the HDMI cable to connect the HD Cable Box to the TV. I may yet be able to control everything using the HD Cable Box remote, but I haven't gotten that far yet but I've got Comcast coming on Saturday and hopefully they can let me know if this is possible: let me know if you have a solution.
So here are the components and the cable types used to connect:
HD Cable Box to TV: HDMI cable & Optical Audio cable
Home Theatre to TV: Red, Blue & Green component cables
First off it's always best to start from scratch when it comes to home audio. LoL. Many times I've been in this situation.
So with everything disconnected. You should have your HDMI, COMPONENT, RCA(R,W,Y)
HDMI and COMPONENT are the exact same thing and in all preference COMPONENT is far better thand HDMI for the pure fact that each wire is in it's own casing and insualted to avoid feedback from the other wires.
Anyways, with everything disconnected we begin
From you Cable/satellite box- Run your HDMI cable from you cable box to your HDMI 1 input on your tv.(If your speakers were to work on your tv you would automaticaly get sound and picture)
That should be all that you should be running from you cable box. Now that we have one thing running we go to the next thing.
From your TV run your audio out (RCA Red/White) to your amp. Usually your preference but more than likely your TV IN on your amp.
With your amp now set on TV, you should automatically get sound from your tv. and if your running an HD cable box even though your only running RED/WHITE to your amp, you will still be receiving Digital sound.
Most new amps Should have a digital input and if your running and 1080iUp this one RCA plugin will give you dolby digital sound from your dvd player to your amp. Then running a video rca up to your tv, will give you the picture, while the digital out on your dvd player to your amp will give you dolby digital sound.
It's a basic simple step to get sound. Like a continuing current. So just as long as you have your cable to -- tv -- home theatre. Everything should work. Otherwise I would go and check your cables and make sure they are not faulty.
I hope this confusing walkthrough helps.
If you are connected to a HD cale box using component cables IE (G, R & B) then check if either the Red or the Blue has come loose or unplugged as this will cause most HD sets to revert to a black and white picture.
