The picture is arched down in the middle at the top and arches up in the middle at the bottom.
How do I correct this?
I have a 60" Phillips and a 51" Magnavox and they are both doing the same thing.

Your TV most likely has one or more possible problems.
Problem #1: Convergence Chip Failure ( common problem )
Here are some of the most common symptoms and example photos of a convergence problem
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 tPicture arches down at the top and arhes up at the - 2c07611.pngdirections your convergence chips are bad and should be replaced. This is a common problem.
Solution #1
You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.
Problem #2 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 Picture arches down at the top and arhes up at the - 578ba6c.jpg

Replace the Sanyo I.C. chip on the heat sink of the power supply convergence board STK730-XXX. Last 3 could be 130/010/020, any will work.
