Why is tcl tv saying no signal and volume indicator keeps running back to zero?

After powering on, TV is saying no signal. Also after initially sending up the volume indicator via the remote control., it returned to zero on its own and refuses to go back up to 100 except when I depress the volume button at the back of the TV. however on releasing the pressure the indicator is again returning to zero on its own

SOURCE: tcl led hdtv won't program with comcast remote

If Comcast does not list a code for your TV, your remote probably does not have a code in its library that will work.

SOURCE: why would it get hot once coex cable hooked up and scanning for channels? tv gets hot and shuts off.

I would check that there is not a problem with the power supply to the set. If it gets hot and shuts of the power may be faulty and could be causing component failure.

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

Volume automatically goes to maximum on TCL TV


The volume (+) button on the TV is stuck or soiled if the volume automatically increases when the TV is turned on. To find out:
  1. Turn off the TV.
  2. Press and hold the volume (-) button on the TV then turn it on.
  3. If the volume doesn't automatically increase, you have a stuck button.
  4. If it does increase, you have a faulty key control board.
  5. In either case, you have to replace the key control board.
To find it out further:
Warning: Beware of electric shock.Please do not proceed if you do not have the skill to do the following.
  1. Unplug the TV.
  2. Let it stand for 15 minutes to allow voltages to drain completely to avoid the risk of electric shock.
  3. Remove the screws securing the TV's back cover and pull it off.
  4. Disconnect the cable that runs from the main board to the control key board.
  5. Turn the TV on using the remote.
  6. In this manner you can use the remote control to run the TV while waiting for the control key replacement board.
To do a hard reset of the TV, unplug it and let it sit for 2 hours or long enough to completely drain the internal voltages.

CODE FOR TCL TV UNIVERSAL REMOTE CONTOL-CHUNGHOP RM -133E


If you don't have a code you can do these steps to get your universal remote working with pretty much any tv:

1.) Turn your TV on. Then on your remote press the set button, it's the small gray button above the green button that says TV.

2.) Press the TV button. There should be a red light to the right of the SET button. This means that your remote is ready for the TV code.

3.) To find the TV code, press the + or - on your remote. This is located above the orange buttons. Once the volume on your TV goes up or down, stop pressing the + or - button.

4.) Then press the SET button again to set that code for your TV.

If the above steps do not work, keep trying. It will work! ;)
