Question about Televison & Video

1 Answer

No signal TV powers on but not receiving signal from cable box. It used to say HDMI up in the top right corner when I powered on and then would switch to the cable box and I could watch TV, now this has changed and says DVI (instead of HMDI) and not picking up signal. I'm guessing this is my problem but I dont know how any settings got changed. Thoughts??

Try changing the order you turn on your TV and cable box, don't switch both together. The TV will likely skip the HDMI inputs if there is no signal there. Alternative you can change the TV's source after the cable box is on and that should allow it to not skip the HDMIs. You don't have HDMI to DVI adapter(s) in the line, do you? -Ken

My digital tv is saying no singal whats the problem and how do I fix it? we have a huge antenna on our roof







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.

On my e-motion tv when I switch it on and go onto did it says no signal....help please


Why does my TV say no signal? If your HDTV or Standard TV displays a "No Signal" error message, it may be due to one of the following issues:
  1. Determine how many TV's are affected.
    • If it is one TV, continue to step two.
    • If multiple or all TV's are affected, continue to step five.
  2. Ensure that your HDTV is on the same source/input as your MTS Ultimate TV service.
    1. Press the TV button on your MTS Ultimate TV remote control.
    2. Press the TV/Video button.
    3. Wait 10 seconds.
    4. Repeat steps b and c continually to cycle through all the available source/inputs on your TV until the correct source/input is selected. (ie. HDMI 1, HDMI 2, Component 1, Component 2, etc.) On standard TV's (non HDTV), you may have only 2 choices, TV or Video.
  3. If the source is correct from step two:
    1. Unplug the HDMI cable from your MTS Ultimate TV Set-top Box.
    2. Wait 30 seconds.
    3. Plug the HDMI cable back in.
    4. Wait for the signal to initialize.
    5. Make sure all cables connected on the set-top box and your TV are secure.
  4. If the problem persists:
    1. Unplug the power cable from the back of the MTS set-top box.
    2. Wait 60 seconds.
    3. Plug the MTS set-top box back in.
    4. Wait for the signal to initialize.
  5. If you are still experiencing a problem:
    1. Make sure ALL Ethernet and/or Coax cables are securely in place.
    2. Unplug the power from the MTS box labeled 2Wire or Pace as well as the affected set-top boxes.
    3. Wait 60 seconds.
    4. Plug the power back into the MTS box labeled 2Wire or Pace.
    5. Wait for the broadband light to turn a solid green colour.
    6. Plug the power back into the affected set-top boxes.
    7. Wait for the signal to initialize.
Good Luck

Incompatible video signal has received check output device settings


My guess would be that your PS3 has somehow switched the output settings. You can reset the settings by pressing and holding down the power button till it starts blinking. Try connecting it with your RCA cables to a TV and if that works try going into your settings and setting the PS3 back to HDMI.

I have directv hd service, I recently bought a surround system, can you help me with the connection? My sat. reciever has an hdmi out as do my surround receiver and my tv


It is always helpful if you give model and make of the equipment involved. We can be more specific and accurate that way.
It si a very straight forward connection and you need two HDMI cables.
1) Connect the Satellite Box's HDMI out to the Receivers HDMI In ( any one of the sockets labeled TV/SAT or Video AUX etc ).
2) Connect the Receiver's HDMI out to the TV's HDMI In.
Every thing will work fine except if you switch off the power of some receivers the TV will stop getting HDMI signals ( ie no sound or video if Receiver is Off )

The other way of connecting is to connect the SAT BOX's HDMI cable directly to the TV's HDMI In and if your SAT BOX has a digital Audio out ( Optical or Coaxial ) connect that to the Receivers Digital In. This way you will need only one HDMI cable and one Optic fiber or Coaxial cable. And the advantage is even if the Receiver is Off you can watch video and hear its sound through the TV.

On my sr606 receiver when I hook up the hdmi to the tv i sporadically loose the signal. when I hook the cable box to the tv it is ok. there seems to be a problem with the hdmi interface


Try this. Check to see if you have the cable going round and accute corners. Sometimes the placing of HDMI sockets on the unit mean that the cable is forced into a sharp turn to route it to the cable box. HDMI cable is touchy when it comes to routing. For example an HDMI cable coming out the side of a TV and having to do an immediate 90 degree turn to get to the cable box is enough to scramble the signal. HDMI cable must not be kinked, wound up tightly or forced into tight angles. The worst offenders for this are curiously the more expensive cable as they have a tougher outer shielding that makes them more prone to situations in cramped and tight corners. If you really need to get round a tight corner, try a cheaper cable. Hope this helps

HDMI signal cuts out for a few seconds constantly from receiver to television. It does it when switched to cable box and the roku box. Onkyo TX-SR606 Scientific Atlanta Cable box thru HDMI Roku Box...


Mine did the same thing where the screen would go black for a few seconds and then the picture and sound came back. I would try (1) switch HDMI cables, (2) try a different HDMI input in the back of the receiver, (3) try different input in the back of the TV. None of these seemed to work with mine. I finally ended up running the cable box direct to the TV and only run the audio through the reciever via coax or digital. No more problems. I think the HDMI inputs in the back of the reciever have a problem continuously carrying the signal if it is the leaset bit weak.

Can record Sky programmes but not view live.


You must connect up the TV to the SKY box, via Audio Visual cables too, in order to watch, recorded programs. You need to hook, up, Component, HDMI, or Composite, You select it by an EXTERNAL channel.
Connect the cable running from the wall into the "In" port on the Sky Box HD receiver. This cable brings in the signal to your receiver. Make sure the cable is securely fastened to the receiver, otherwise you might experience image and audio issues.
Attach an HDMI cable into the HDMI port on the Sky Box HDTV receiver. The HDMI is a single cable that provides both HD audio and video signals.
Plug the other end of the HDMI cable into an available HDMI port on the HDTV.
Power on the HDTV and the Sky Box HDTV receiver. Press the "HDMI" button on the TV's remote control. This will display the cable contents of the HD receiver onto the television.

Remove the HDMI cable (out) to the speakers from the receiver.
Connect regular speaker wire from the receiver to the speakers.
Of course, remove the (now extra) HDMI cable from the tv.
That will remove the loop.

DVR/TV connection


With the RGB you have to run seperate audio ,I think you have ran the seperate cables for the sound but they are in the wrong place.try changing the RW from the DVR to the TV and you should get sound from them.The unfortunate truth about the HDMI is that the HDMI format has a problem effectivly communicating between components.I am a Directv certified High Definition technition and %50 of the TV's that I connect the HDMI to will not receive the signal.One trick that I have found that works is to make sure you have a picture on the RGB then connect the HDMI.Once you have these connected ,turn your TV off and unplug the power cord from the DVR for 30 sec then plug the DVR in and wait 5 minutes for it to power up then turn your TV on and switch to your HDMI input.This method sometimes works to "Jumpstart" the HDMI input on the TV .There is no guarantee that this will work but is sounds like for now this is your only option,GOOD LUCK.

Receiver won't put out sound to LCD Sharp aquos


I have the same problem with my Sharp Lcd and Onkyo 804. I believe one problem is that the TV can not accept dolby digital or dts digital audio signals through HDMI. It will play sound if it receives a PCM signal through HDMI. You can try switching the type of signal on the cable box settings and on the dvd player. I switched to PCM and got sound through the TV and the receiver. The problem is that PCM is usually only a 2 channel signal and Dolby 5.1 will sound better through the surround sound theater system. I have not found an absolute solution to this yet, but I am willing to not get sound through the lousy TV speakers in order to get top notch sound through the Onkyo.
