Screen says no signal. when i push the input button,tv says no signal not available Stuck on the blue screen, there is NO lock icon on the screen. I have the same problem. I attached the cable from my old analog tv to my new HD TV, plugged it in, turned it on and got "No Signal". Do I need to buy a different kind of cable for the HD TV?

You may have the wrong input source selected. There are a number of different source connections on the back of today's TV sets. Using the remote's SOURCE button, cycle through the different inputs until you find the one that your input device is attached to. It is common for users to inadvertently cycle off the correct input when pushing remote buttons.

Your TV probably has multiple "inputs" (coax, HDMI, component, et cetera). Use the "input" (or "source") button on your TV to cycle through all those available "input" streams.

If you select "coax", and there is *NO* coax cable connected to the back of the TV, you *WILL* see the "blue-screen". Select a different source that is "active".

the button will be labeled either source, input, tv/video. if the direct TV remote was programmed for your television there is a tv/input button

I HAVE FOUND THE ANSWER!!!! I just bought an TCL TV last night and was given the wrong remote. Screen was stuck on "no media" screen BUT I noticed that when I turn the tv on and keep pressing the menu button, the menu screen would pop up for a half second before the no media screen popped up again. So I knew it was able to access it. SO, it took a few try's and with no exact method I turned the tv on, waited til I saw the TCL logo and then simultaneously pressed the menu and channel up button repeatedly. It will open the menu for you and allow you to move between the input channels!!!! It WILL take a few tries to catch it but it worked!!! Your welcome!!!!

Have you tried to push the tv input button? Sometimes when a button is buy accident it changes the input on the tv. Hope this works, let me know.
Good luck, Toni

HERE'S THE FIX: I just went through this with my Vizio VX37L. TV is stuck in RGB input. This is the fix.... TV is stuck in RGB input.
(option 1) Power on TV, and press the INPUT button repeatedly and rapidly until you can change to a different input, such as AV.
If that doesn't work, try:
(option 2) With the TV off, press and hold the INPUT button on the side of the TV for about 5 seconds. The TV should power on and the input list will appear. The TV will no longer be locked, and the INPUT button should function properly after that.

Option 2 worked for me!

i would suggest cycling thru the inputs- av1 av2 rgb hdmi. blue screen is indicator of no input.

Try resetting the TV to factory settings thusly:

Turn on the TV. While holding down the RESET button on the remote
control, press the POWER button on the TV. (The TV will turn itself off, then
back on again.) Release the RESET button.

With out turning on the T.V., Push the [Input] button on the remote control. The TV should turn on and activate the input menu, just continue to push [Input] until it is set on TV (or HDMI, etc.). this should solve your problem.

push the PIP button until it says off
