Re: no sognal

The remote may be accidently commanding the TV to change its input selection. Try taking the batteries out of the remote and see if it continues to do this.

Could you please tell me how to reset my tv? I have a blue screen

Proceed with the troubleshooting steps below only if you're seeing:
  • Black, blue, or gray screen
  • "No Signal" message without the DIRECTV logo
Note: If your TV screen appears "frozen" or you're seeing wavy lines or overlapping images, try this.
Solution 1: Check that your TV is set on the right input

[img border="0" alt="Image" src="">Using your DIRECTV remote control, press the TV Input button to cycle through TV inputs (Component, HDMI, etc) until you see a picture. If nothing happens when you press the button, try programming your DIRECTV remote to control your TV Input and try again.

Note: You can also try changing the TV Input using your TV remote.
[img border="0" alt="Image" src="">If you're still having issues, check the cable used to connect your receiver to your TV.
Still not seeing a clear picture?
Continue to Solution 2.

Solution 2: Reset Your Receiver
[img border="0" alt="Image" src="">On some DIRECTV receivers there is a red reset button located inside the access card door on the front panel. Press it, then wait for your receiver to reboot.

Note: If you cannot locate the red reset button or your receiver does not have one, unplug the receiver's power cord from the electrical outlet, wait 15 seconds, and plug it back in. Then press the Power button on the front panel of your receiver and wait for your receiver to reboot.

If it shows "No Signal" it means it. It do not get any signal to display. Check all the settings. Refer its user manual for details. First, try to tune it to on-air program, by do an auto-tune function, after connecting it to an external antenna. Refer its user manual for more details. If it do receive all the channels transmitted, means, the set is OK, and the fault will be with the input selection, you've done. OK?

I am not getting picture on my TV it stic on only one channel we are chengiong channel but same sound is comming also we are getting a blue coloured K on right hand side of TV

That blue K means you are in the service mode. Unplug your set and wait 30 seconds. Then at the same time you plug it back in, you need to be holding the volume down button and the input button.
The TV should turn back and the blue K should turn pink. Once this happens, press the volume and channel down button at the same time. A menu should come on the screen. With your remote, press the up arrow to reach the nest page. The first option should say INIT. Arrow to the right and hit enter. In a few seconds your screen should turn green and say success. Unplug the TV and wait 30 seconds. Plug the set back in and turn on your TV. You can then set your set back the way you want.

The tv had blue screen briefly showing "no signal" then turns off. ... and I am getting the same blue screen-no signal.

If your television is displaying a blue screen or no signal message and then turning off, your TV may be at an inactive input. Here's how you can get back to watching your TV:
1. Powering on your TV and press the INPUT button on the VIZIO remote control repeatedly until a picture re-appears.
2. If this does not work, try again but press the button slower this time.

I got this off the vizio website.

The dogs rolled on the remote and the tv went to a blue screen and turned off. Every time you turn the tv on now it is a blue screen and says no signal and turns off after 10 seconds

This sounds as if when the dog rolled on your remote he has pressed the source button so that you are no longer on the TV cahnnel. The TV is looking for a different input eg. AV1/AV2/HDMI etc. This will give you a blue screen & as there is no signal the TV will switch off. Check on the remote for an Input or TV/AV or source button & make sure this is set for the TV signal.

Just hold down the input button on the right side of the tv. This is the bottom one. So,
With the tv off,
press and hold the bottom button (input)
when the tv turns on, and you see the input menu
release and press the button to put the tv into a mode that works!

TV Picture cuts off.

The blue screen means that you have lost signal. If the set don't have signal for so long it turns itself off. "power saver feature" Check all connections or replace cables, If that don't work the signal board may be going bad.

To fix the problem, try turning off the TV and unplugging it from the outlet. Once unplugged, push the power button and hold it down for 1 minute. Then turn the TV back on and rescan for channels.

If the problem persists, contact LG customer service immediately as there is a problem with the memory card. The device is unable to retain scanned channels for immediate feedback.

All LG LCD automatically comes with a 1 year manufacturing warranty. You would have to provide proof of purchase to show when it was purchased. Hope this helps. The Guru
