Hi,

It's a convergence issue. Go into the main TV menu under video settings and look for convergence. If it has an auto convergence select that and wait a minute the TV will adjust itself and give you a clear picture.
If the TV does not have an auto convergence and just regular convergence than select this. It will give you a grid pattern on your TV and you have to move the cursor (using TV remote) and adjust each "point" so that each line is perfectly white. If you notice red or blue anywhere on that "line" then you have to adjust using the up, down, left and right arrow keys to "line up the red and blue lines with the nearest white line. It takes time and patience to do, but when completed, all lines on the grid pattern should be pure white and you will have a great looking picture.
You have to do this will all TV inputs (Video1, Video2 and so on) the reason Zoom looks good, is because you never used that screen as much and so the lenses didn't have a chance to get out of synch.
RPTV's are made of the three lenses (red, Blue and Green) and as you watch TV, these lenses slowly get out of alignment. So you should do a convergence about twice a year to make sure nothing is out of whack.

You can pay somebody to do it, but may cost you like 100.00 or do it yourself, it is very easy just tedious and time consuming. If you have the auto convergence than your golden because this is the easiest way to "reset" the TV.

Hope this will help in solving the problem....

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.

if you have no experience repairing TV sets your going to have to have a tech replace the convergence ICs they are soldered into place and will probably need to be readjusted when this is done. if you know how to work on tvs then replacing the STK type ics in a pair is whats needed Good Luck
