If it still plays games, I wouldn't be to worried. These old consoles can be moody. You might try cleaning the dust out of it and check your AV or RF connector, (which ever you are using).

Good luck.

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.

Blury screen with rainbow image cannot read words on screen


The convergence integrated circuits have failed and most likely the 2 5A fuses have opened as well. I would find a local Mitsubishi service shop.

Tv needs fixing, advice appreciated


it would intermittedly display a bowed rainbow effect and the picture would jump to that/black/back into focus. it was nothing but due to change of place due to decaussing ckt to take care of magnetic effect of earth. this morning i turned it on with a black screen. It has audio but no video. your problem it sounds me that it is due to loose contact or loose connector or due to video ckt. as you said that sudio is ok. if you are not tech person call skilled tech to fix it .it is not a major problem. hope this will help you please let me know what happened.
