    OK,

    Then noise would be spark of high voltage wire due to lose fitting, coming from flyback and going into high voltage block.

    Only electric spark can produce such noise which affects TV as VCR tracking noise.

Could be anything in the high voltage section of the set going bad caps and bad soldier on fly back can also cause this to happen.
set needs to be checked out by a tech.

Blue and red lines across the screen in a rainbow pattern


Projection sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3d, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then yourconvergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....

  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. The power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

It sounds like you are going to need to have the convergence IC's replaced. Not really a hard job, but the job requires the proper tools, soldering skills, and a service manual to get the proper part numbers and to perform convergence alighnment in the service menu after the IC's are replaced. Good Luck
