When I tv turrns you can see the picture then it sudenly turns to 5 big horizontal re,white,black,blue,green, in color my front power,menu,volume,and chanel buttons also do not work this lines are rolling.
I had the same problem. I bought the TV with the same symptoms and couldn't find a solution. So just on a hunch I tried different button combinations on the front of the TV while I turned the main power switch on in the rear. One I got to the Channel up and Channel down the TV came to life and works great. So just hold those 2 buttons down at the same time while you flip the switch on the back. Hold them for about 10 seconds and then you should be good to go.

If your tv has a custom settings area, first turn all color down on set so picture looks black and white. Now in color settings look for red blue and green color bars. Use the bars until the picture looks as true to black and white as possible. Also, try changing color temp.
Do adjustments on focus block. Will have to open front panel access door, focus block blue will be on left, green will be on top. Top screen bottom focus. Turn clockwise to increase, counter clockwise to decrease brightness. Turn the color all the way down on menu where it's pure black and white and make adjustments for perfect black and white picture, then when you adjust color, it will be perfect.
It is possible that you have a shorted green CRT, you can remove the front speaker cover, and you will fine a focus block, and if you turn down the green screen voltage, very slowly, the green should turn down. if not then the gun (CRT) will have to be replace, If it does turn down, then go into the menu and turn the color are the way down and that should give you a black and white picture. If it is not black and white. adjust the red, blue, and green screen voltages until you receive a good black and white picture. Turn slowly they are touchy, and if turn to high, you will get retrace lines and the TV will shut down.
The 37" Vizio I just bought has a very confusing feature where the same input can be used as either the Y channel of the component or the full video channel for composite. If you plug a component source into the TV and then select the composite input ("AV" on the remote), you will see a black and white version of the full component signal (makes sense as the Y channel is just the luminance component). As sad as it is, I was stumped by this for a while until I happened to hit "COMP" and got full color. FWIW, the manual warns about this, but it really doesn't emphasize the point. I wonder how many returns they get because of this.
i had the same horz. lines in my t.v. I called everywhere and ended up fixing it myself.(The solution on my t.v. was to unplug the set hold in both channel buttons and plug the set in at the same time you hold the buttons) it then reset the t.v. lots of luck.Bob p.s let me know if it helped you.
go into menu turn color off see if you have a black and white picture if not adjust red,green, and blue screen drive on controls in back of tv you have red, green, blue it will have focus /screen controls cover each tube do one at a time blue focus and screen drive adjust to clear blue picture do all 3 tubes, then adjust them to where you have a black&white picture once this is done turn color controll back on.Thank You for using FixYa and Have a Nice Day.
