Switch to the an input that is not being used. The bars are present, go into the menu and reset the tv to factory settings. If the bars are present it would indicate hardware failure.

If the blank bars are not present on the other input, something is going on with the cord, or a setting in your set top box

My tv stopped showing picture but still apperears


If the whole screen is just white light, the the LCD controller (t-con) board may have gone out. Your TV can have more than one version of the boards inside.

Screen changes between color as a demo function.no signal


Gateway was sued Class action over LCD's and Plasmas they sold over a 2 year period. They resell 3rd party TV's that were very faulty, an immature design.

Here's what I learned about mine, which makes it limp through as a Computer monitor (both DVI and VCA) and halfway functional TV.
You have to connect a DVI source, on the Main Menu for the DVI input there is an option called "Factory Mode". scroll down to it with the CH buttons and select it with the vol button. The scroll to "initialize eprom", select and confirm it. After the "Waitting" words disappear, make sure you have a TV source connected, Then turn the TV off and on, using the hard switch in the back. The TV input should be defaulted to channel 10 or 11 now But you select a TV channel that has no TV signal on it (like channel 1 for example) , the whole TV input side will refuse to let you select it again, and you'll have a blank screen and have to start over.

That takes care of the blank screen thing Now the other problem is parental control is defaulting to "ON" or something, and you can't program channels. With the TV input Main Menu engaged, select "Setup Menu." If you have this problem, then you'll only see 2 options, all the TV input and channel programming options will be missing. You have to select Parental Control, and when it prompts you for a password hit the volume > button 4 times (or just wait for a minute.) This should bring back your TV System and auto prgram/manual search options.

Unfortunately, my TV doesn;t remember these setting very well if I select cable, it does better if I select "AIr". But at least it funtions - kind of. If you switch to your computer input, you probably will have to switch the monitor off and on from the back panel again. Mine always starts up with the menu onscreen. All this might bve less trouble if you have a the remote, I don;t know where mine went after the last move.

Good luck, and hope this helps.
