Input Signal between TV and satellite dish lost

No you don't need a new tv. Hook up your HD cable box using HDMI cable. Hdmi out on your cable box then hdmi in on your tv. You need your tv remote to change source input to hdmi.

Connect a known working DVD player by using a new HDMI cable to HDMI INPUT 1 and check for signal.
If you have a DISH or CABLE system box, connect that also with a new HDMI cable to HDMI input 2 or 3 and recheck for signal. Your T V remote will have an input selector to change between the different inputs on your
T V.

First we need to know a little more details about the kind of TV you have, the kind of service (Cable, Satellite or off Air).
Comparing showroom to your home is also something we need to know. Was the showroom using Cable or Satellite. Satellite will always have a better picture quality wise.
If you are using composite input for the signal path between TV and source this would not produce a High Dif picture Composite = Yellow for video, red and white for audio. If you are using Component source that will produce a HD signal cable is RED/BLUE and Green with different audio.
The best quality is using an HDMI cable, this is all in one cable and the sources is the best. One last thing, if you are using the RF *cable as source it will not give you a quality signal.

Based on what you're saying it can only be a few things.
Trying putting the HDMI cable into a different port on the tv and change input.
Try changing the HDMI cable.
If that doesn't work, change over to component cables, change TV input again and see if that works.

test this steps and fix it. God bless you

     Check the back of your Sharp TV for the HDMI input. These will be long, thin rectangular jacks labeled "HDMI." Most Sharp TVs will include another label on those jacks with an input number ("Input 5," "Input 6" or the like). Remember that number. It will have a bearing when you turn on the TV.

     Connect one end of an HDMI cable to the input jack on the Sharp TV and the other end to a compatible component such as an HD DVR from your cable/satellite company or a Blu-Ray disc player. The TV won't broadcast in HD if you can't connect these devices with an HDMI cable (though it will still broadcast in standard definition using RCA cables or S-video cables).

     Press the "Input" button on your remote. A list of signal sources will appear on your screen ("Input 1," Input 2," etc.). Use the cursor to maneuver down to the input number corresponding to the HDMI outlet you just hooked up and press the "Input" button again.

     Press the "Menu" button and maneuver the cursor to select "Option." Go to "HDMI Setup" and press "Enter." Move the cursor up or down to the desired item and hit "Enter" again. Then move the cursor from side-to-side to select the proper setting. Hit "Enable" to allow the Sharp TV to automatically recognize the HDMI signal and "Digital" to get the proper audio signal from the HDMI cable. Then hit "Enter" again.

If your Playstation is putting out the signal in 1080p then try changing it to 1080i and see if that works. Not all TVs are compatible with 1080p.

hi First, remember the old HDMI reset tech tip. Unplug all HDMI cables (one end will do.) Then remove power from all things in play. No, not just turned off but remove the AC. Wait 5 to 10 minutes, hookup re -test thanks

OK. For all you regular Joe's like me here's the fix--plain and simple! I have Dish Networks HD receiver, an LG Home Theater System (LHB953) and an LG HD Television - although I suspect this applies for most LG TV-to-LG Audio Systems used in combination with a HD TV). My problem lied within the LG to LG setting known as SIMPLINK which tries to "auto-configure" everything between LG to LG devices.

Do this to make your HD TV (using Dish/DirecTV) play it's HD video display from the satellite provider but play the audio over the LG surround sound speakers:

1. Plug a HDMI cable from your satelite receiver's set-top-box to your HD TV. This will carry your HD "video" ONLY. Click "Input" on the TV remote until the HD video signal shows your desired TV channel from your satellite provider.

2. Plug an HD Optical cable (the one with the red laser) from your LG HTS (Home Theater System) to your satellite box. This will carry your HD "audio" ONLY.

3. This is the magic everyone seems to be overlooking. On the LG TV remote, go into the menu options and disable SIMPLINK by setting SIMPLINK=OFF. This feature allows the video and audio signals to be split over 2 different ports: HD video goes over the HDMI cable and the audio to go over the HD Optical cable.

Hope this helps!

why hdmi input wont show up

Hi. You will love the dish. I have enjoyed it in my home for a number of years. I like the HDMI cable because it is the best quality and simple to install, one cable does it all. If you don't have one yet get it at walmart where it is about half the cost of other retailers. All satellite TV is HD without you doing anything special. So yes, it will do HD from whatever input you choose.
