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.

Sometimes I get a rainbow on the bottom of the screen.


Your TV most likely has a convergence failure. ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem


  • 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.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

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

Andy

You have a convergence problem. Go to the convergence menu or consult the owners manual on the convergence procedure and try to correct i if you can.. However if the red image is bowed and or not linear you will probably need to call a technician to repair your set. Most likely the red convergence output chip has failed. This is a common problem with all CRT ( picture tube) rear projectors. Good Luck. Happy Easter
