If this is a direct view CRT television, it should straighten itself out on its own after a few off on cycles as the internal degausing coils will pull the purity back. It may take 30 or 40 cycles to do this if its a CRT television. What is the model number of your set?

Broken screen


You can buy the screen from shopjimmy.com if they have any in stock. Usually you will not find the screen easily and even if you find, it is expensive. Its better to buy the new TV instead of investing money and wasting time. Replacing screen is also time consuming and not easy.

Blue spot on screen


  1. First, look for the source of the problem. Large speakers, especially older ones, are the most common offenders. Notice the position of the blue spot on the screen (left, right, upper, lower, etc.) for an indication of which direction the magnetic field is coming from.
  2. If you think you have determined the source of the magnetic field, try moving the object away from the television screen. If this does not work, continue looking for other potential causes.
  3. f you are unable to determine what is causing the magnetic field, try moving the television. Sometimes magnetic interference can come from a neighbor's equipment, especially in apartments and condos. Moving the television to another part of the room, away from shared walls, may help.
  4. If none of these techniques succeeds in removing or improving the appearance of the blue spot, try to find if their is any demagnetizing coil button available in front of the TV panel , it may be symbol like magnet and a diagonal line on it

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!

I accidently held a magnet up to my TV screen and its busted up. How do I fix it?


Magnets and projection screens do not mix well. When you say `busted up` it could mean a few things.

If it means blotches of color on the screen
-Caused when your projection TV becomes magnetized.
Fix:
-Use a strong magnetic coil and make circular motions around your projection TV screen starting on the upper left corner.
-Increase the size of the circles you're making until you've covered the entire screen. Slowly move away from the screen; continuing to make circular motions with the magnet.
-When the magnet loses contact, the color blotches should be gone.

hope this helps
