try reseting the tv and remote.....unplug tv from the wall plug for 5 mins. then remove batteries from remote.....from left to right at the top of remote hit all the buttons on remote then put batteries back in try that......

The fault is with its main board itself. It will be best to get this set repaired by skilled technicians. This is not a user repairable one.

Will need to know what tv you have, but you are right it is probably your input button. if you pushed it on your remote then there should be an input button on remote. otherwise you will have to go into the tv menu and setup it up there.
if you respond with model and make of tv, might get more info.

See my solution <http://www.fixya.com/support/t2795690-convergence_off_blue_line_only_vertical>.
You need to get to the service menu--it's been 4 years so go to AVSforum.com to turn off the different guns and get the better pattern.
At your risk: To get into Service mode:
1. Turn your TV on. 2. For X81 or earlier series: Press MUTE on your remote and release. 2. For H80/H81/HX81 series: Press MUTE on your remote and release two times ("Mute" on-screen) 3. Press down MUTE on your remote again and hold. While holding, press the MENU button on your TV set's front panel. 4. Release both buttons. 5. An "S" should appear on your screen. Press MENU again on your TV. 6. Now you're in service mode. Channel Up/Dn - Scrolls through Parameters and Volume Up/Dn - Changes Parameter Value
To get into convergence mode:
Get into Service mode, then Hit '7' to bring up the convergence grid. Buttons 100, 0, and ENT control which gun you want to turn off (if you want to align the red to the green without seeing the blue gun and other variations). 2=up, 8=down, 4=left, 6=right, 3=change gun to converge, 5=converge that point. To exit convergence mode you press 7 once and your screen should look like it's imploding then return to normal and then you press 7 to get back into regular service mode.
I have more info found on the board. -Ken

look on the remote (tv and dvd) for a button that says "info" or a button with a picture of a tv with a symbol in the corresponding corner. WOuld help to know the make and model for both of these.

I had the same problem and I found out that the philips universal remote works! What you will do is follow the instructions in the book and your channel will change to the same channel. The instructions are: Hold the select button for about three seconds and click the TV button. After this you will hit the channel button until the channel on the TV appears in the upper right hand corner. After this you will hold the mute button for about 3 seconds and the release. This should work! Hope this helps you out!!!

try pushing the menu button on the tv and mute biutton on the remote at the same time and hold for 5 to ten seconds a reset screen should appear

I'm not sure what type of TV you are using,, but most all Large Screens have a reset button someplace. You should be able to reset the TV and fix the problem. Its not the remote, making the image appear, but a command from it was misinterpeted. Sometimes turning the set off will work, but most often it needs to be reset.

EXCEPTION... if you are using a cable box. Disconnect it from power, wait 1 minute and then see if the problem exists. If the cable box is on even with the DVD you may still have this issue. Please reset the cable, and if that doesn't work, reset the TV.
Thanks! //D

Use the original remote with the tv on hit the F button at the top and the mute button at the same time. Worked for me. Hope this helps.
