Do lamps have adjustment? I have a yellow and blue rainbow effect along bottom of screen. I am pretty handy and well equipped.


This would be a convergence adjustment. Check your user menu on the tv. Look for an item under video settings for a something called "Converge" or "Convergence". See if you can adjust it enough to fix the problem. If not, you may need to access the service menu and adjust from there.

The screen has a rainbow of red blue and green on bottom


The specs say this is a CRT type projection system, so it could be related to the display or to the TV. Since this has an SD card, it might be good to plug in the memory card with some pictures on it, and see if the problem persists with a source other than the tuner. That might at least narrow down whether you have a display failure/adjustment issue or something else.

Video distortion


You need to take your tv in and have the picture deflector re-aligned.  This doesn't cost much, My dad had to do that to his a few months ago and it cost 30 bucks.

Yellow area on screen


either burn in or magnetic field interference. I suggest moving any speakers away from the tv. if thats not the case, then find a strong magnet, make sweeping motions across the screen with it but dont touch the screen! Keep doing this until the colors change, then "sweep" them with the magnet into a corner and they will mostly dissapea.......r, sounds complicated but worked for me. can be scary so dont try unless sickly despearate or confident.   Hope This helps!

Blue line trouble


Hi Kracka,

Are you able to post a picture of the problem?

It sounds from your description that it might be a 'convergence' problem which is when the red, green and blue parts of the image aren't alligned properly.

Check in your menu to see if there is a convergence setting.

Hope this helps
