HDMI cables give no picture they say check signal cable
I had a problem with my tv but it was fixed by one of your experts -welcomejee. It can be found under generic problem for all Flat Panel Televisions ''I have a Samsung lns469dx-xaa. Basically I had no picture but only sound and had to replace my T-con/LCD controller board. After I did this I plugged in the HDMI cable and got great picture and noticed it would come and go and I had to play with the cable in the back until I finally got it right. I went to the store to pick up a shock protector for the tv and cable box and when I came back the hdmi cable did not give me any signal. It said check signal cable or no signal. I checked both ports but still no luck. I called the cable company and they troubleshooted over the phone with me but still to no help with getting a picture through the cable. So the cable company sent over a tech to see if it was the cable box or my hdmi cable. The tech said the box was fine so it must be my hdmi cable. I can watch tv through the audio/video cables but why do that if you can watch it through hdmi cables. So on Friday I went and bought a new cable and tried it out. Still the same thing. In both ports it says check signal cable or no signal. Can someone please help me so I can finally fix this tv once and for all. Thanks, Erik

Re: HDMI cables give no picture they say check signal...
Hi Thanks for using FixYa. Due to two things that will
cause the no signal message to come up are, no data available for closed
captioning and a weak signal input. Your TV is in the Closed Captioning Mode.
To turn off simply bring up the on screen menu and scroll down to the part that
says closed captioning and turn this function off! With the closed captioning
block displayed and the program being viewed is not sending out closed
captioning signals the TV will display, No signal! If this doesn’t resolve your issue then the problem may be
with the processor failing and it is causing a random read of the EPROM to
display the no signal message. I’ll suggest you to run the HDMI from the PVR (personal
video recorder) directly to the TV (mute the TV), and then run the optical
audio from the PVR directly into the receiver's optical in. The closed
captioning is something that is addressed in analog broadcasts, but not
necessarily the digital broadcasts. Try using Component cables if this doesn’t make a
difference. After using components cables your issue will be resolved. Please do accept the solution if the issue is resolved or
else revert for further assistance. Thanks Rylee

1 – Is the NO SIGNAL issue happening on just one TV?
CORRECT INPUT or SOURCE
If it is just one TV that is showing the NO SIGNAL…
-Be sure your TV is on the correct source or input as your CABLE or SAT BOX.
-Press the TV button on TV remote control to turn your TV ON.
-Press the INPUT button on your TV remote control.
-Cycle through all the inputs on your TV.
-Do this until you are on the INPUT your CABLE or SAT BOX is plugged into.
-You should then see the CABLE or SAT programming show on your TV.
HINT: Your TV will most likely list the TV INPUTS as: HDMI 1, HDMI 2, HDMI 3, VGA, Component 1, Component 2, and so on.
If you still see NO SIGNAL on your TV screen, see the next step below…
2 – If you have your TV on the correct INPUT or SOURCE and you still see NO SIGNAL…
CABLE OR SAT BOX NEEDS RESET
-Remove or unplug the power cable from the Cable TV or SAT set top box.
-Keep it unplugged for 2 to 3 minutes.
-Plug the power cable back into your Cable or SAT set top box.
-Give it some time for the Cable or SAT box to power up, get the signal, and initialize.
If you still see NO SIGNAL on your TV screen, see the next step below…
3 – If you have reset the Cable or SAT box and still have the NO SIGNAL…
UNPLUG THE CABLE GOING FROM THE TV TO YOUR CABLE OR SAT BOX
-Remove the HDMI cable or other cables from your Cable TV or SAT set top box.
-Keep the cable unplugged for 2 to 3 minutes.
-Plug the HDMI cable or other cables back in.
-Give it some time for the Cable or SAT box to get the signal and initialize.
HINT: Make sure all the cables that are connected to your Cable or SAT box and your TV are tight, undamaged, and secured.
4 – If all of your TVs are affected with the NO SIGNAL screen…
BE SURE THE COAX CABLES OR ETHERNET CABLES ARE SECURE or CABLE OR SAT IS DOWN TEMPORARILY
-Be sure to check the ones where the CABLE or SAT come into your home.
-Be sure ALL Ethernet and Coax cables are secure.
-Call your CABLE or SAT provider to see if there is an outage.
-Realign your Dish if you have SATELLITE.
You can use an HDMI cable if both your tv and Blu-ray player have that imput. That will give you the best picture and sound. Both video and audio are carried through the one cable. Next down in quality are Component cables. You may need to use these if your tv doesn't have an HDMI input. These 3 cables are red, blue and green. They will give you the picture but no sound. This is normal . All component cables need red and white composite cables for audio. When you have made your choice of HDMI or Component, click the input button on your tv remote and scroll down to either HDMI 2 or 3 or 4(if you used an HDMI cable) or choose "component" to allow the signal to come through. Make sure you at least have the blue-ray player on so that when you do see it on the screen, you'll know which input you chose to get it to come through. Remember, after watching your Blu-ray, remember to turn your input back to your cable setting so you can watch tv again
You also need to check that you have set the output of your device to HDMI and the input of the TV to HDMI. In the past the TV may have automatically selected HDMI when the device is turned on but sometimes that does not work.
Might some how got that HDMI input port shorted?Tries tv unplug and that HDMI cable input it into another HDMI port,replug tv back about an hour later.So the tv resetting itself back to factory setting.Tv on goto tv menu,goto tv PICTURE SETTING going down to do resetting.This should resetting the whole tv Tuner signal board.These steps,should help ur tv HDMI ports functions again.
I gather from the information given that you are getting the proper signal from the cable receiver but there may be a settings issue with the LCD TV. If the 720 plasma is giving good performance then it has to be settings on the lcd . I would review the instruction manual to see if you have over look something that is a proper cable select ( hdmi or vga). If you have selected vga you will not get a clear picture in that mode. HDMI is High definition which works properly with 1080P mode. If you have further issue the manufacturer troubleshooting or Knowledge base will give answers also. 1. check your HDMI cables make sure they are properly seated in the input ports squarely not at an angle. 2. If you are using a cable receiver check the connection there. Make sure you have the proper cable for your receiver to the TV 3.check channel to see if you TV is selected for channel 3 or 4 as recommend in the instruction manual 4. check the V-chip setup it may be blocking certain channels 5. check you picture modes each channel can have desire picture setup modes. 6. If you are using rca cables you may not get the proper picture as you would with HDMI cable that are specially designed for High Definition TV
You will need to run HDMI directly from TV to Cable Box. Then run an optical or digital coaxial from your cable box to your receiver. The version of HDMI in your receiver is 1.1 or 1.2 and will not pass signal correctly. The recording industry has placed many roadblocks in front of HDMI to keep us from recording.... Go figure... That's the fix though. Hope this helps
Yes, there are several ways to hook up your HDMI to your TV but first, we need to understand that HDMI carries both audio and video signals though a single cable in digital form.
I am assuming you want to connect a device such as a digital cable box, Blu Ray or HD DVD player with an HDMI output to your TV. Since your TV has both digital (DVI) and analog (S-Video, component, etc) inputs, my suggestion would be to get and HDMI to DVI adapter (about $20 at buy.com) for your video and for your audio, use any RCA audio cable (I use the one from the Dollar Store). This would give you the best video resolution from your source device.
My next suggested solution would be to get an HDMI to component video + audio cable (< $10 at eBay for a 6' length) for a single-cable fix. Again component video carries analog signals so the DVI could be a better viewing experience but because the cost of the cables are minimal, I would try both solutions to see which fix would give you the better picture.
Note that since the audio is being run though RCA connectors in both instances, the digital Dolby, 5.1 or 7.1 surround sound tracks in high definition sources will not be reproduced if you connect your TV's audio-out to your audio receiver. To get the best audio, I would connect the HDMI device's digital out (optical, coaxial, etc) directly to the receiver.
For connections of audio, so that you can hear all tv audio through the surround system, connect either an optical audio cable or red & white analog audio cables from the tv to the home theater. If you are using optical audio, there is a plug on back of tv labeled for digital audio output and an input on the surround sound system. If you plan on using analog red and white, use the PROG OUT red and white output jacks on the back of the tv to the AUX input on the home theater.
For video connections, to get HD you will need to be using either HDMI or Component cables. HDMI is the cable that will provided 1080p signal (the best HD signal), but if the source does not output 1080p, then your tv will not display 1080p. Most cable boxes output at 1080i or 720p when on HD stations. This signal still provides great picture quality, but HDMI is not needed to get these HD signals. You can use component cables for your cable box and the DVD player output to the tv for video. HDMI might give you a slightly better picture quality but the signal will be the same.
To make the connection, you will want to connect from the cable box to the tv (component or hdmi). Also from the home theater system to the tv using hdmi or the video cables from component (red, blue, & green cables).
My 42" Westinghouse HDMI inputs just stopped working. I thought it was the TW Explorer 4250HDC issue so I got a new one from TW. Still said no signal from HDMI. So, I shut the TV down and pulled the power cord out of the back. I waited a few seconds and reconnected the pwr cord. The TV "re-booted" so to say and now the HDMI inputs work. I think TVTEK has the right idea that it is firmware/software related. In the mean time, you might want to give that a try.
