Question about Sony KP-57WV600 57" Rear Projection HDTV-Ready Television
I'm not quite sure what it's called buy my set appears to be 'zoomed' in about a quarter to half inch so that the top/bottom/sides are cut off slightly. I'm not in the TV's picture zoom mode either. It's very annoying when playing games since meters/health bars and even text is cut-off. It's been like this for quite some time. Flash focus seems to help a tiny bit but not enough.
A friend has this same exact television and the same problem so we are looking for some assistance. Thanks!
Your TV most likely has one of two 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 them in all directions your convergence chips are bad and shoScreen alignment problem (overscan?) - 2c07611.pngaced. This is a common problem.
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 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.
