Color problems, do not know original settings

Posted by on

  • noemaniago Jun 23, 2008

    first, one of the color disappeared, looks like the green color vanished and the pictures turned to be more red. It was like this for awhile. Then I'm getting double images on the picture and smaller until recently no more picture and the screen turned blue. Then I heard popping noise and smelled smoke. Immediately unplug the set, removed the sides, rear and front covers to investigate. Found that the middle tube circuit card assy to be burn't.

    Can you send me a manual, schematic diagrams and a troubleshooting guide, so that I can pinpoint the parts I need to replace and order, so I can restore back our tv set.

    TV Set Info: AKAI

    Type : 55W3

    Model : PT5598HD

    Serial # : 3800?CEWC00408X

    Made: Mexico

Adjust color, need service manual


On controlls the foucus...the other the brightness. I would not mess with them. 99% of the time the problems is one of the two listed below...

You have one of two problems. Sometimes both.

Problem #1) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

Problem #2)

Your TV may have 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.

Color wheel


could be a jumper on the DMD board that must be removed, look for a small sticker that points to the jumper, or it could be a setting in the factory mode, mute-182-power will get you in there, check the settings for the color wheel

Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem. Doing so will only make things worse. The blog does however show you how to fix other common problems with these sets.

  • Screen looks 3D
  • Colors don't line up
