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.

Solution #1
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.
Solution # 2
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.
have tried auto magic focus & manual. Auto Magic focus stops before it has completed and a green 5 appears at the bottom of the screen. For the same problem on this site someone said that the convergence boards need replacing & it is not something a layperson could really do & to call a repair man. If this is going to be costly I would rather not bother. Just wondering about a ballpark estimate as to what something like this costs...thanks for the help
Have you attempted to set the convergence manually?
Consult your manual on instructions to do so.
