Question about Sony KP-53V35 53" Rear Projection Television
I am having problems with our Sony kp-46v35 (1996). The picture arcs, RGB stripes show in a bow at the top and the picture flips upside down and right side up continuously (sometimes zooms in too). The same result with all inputs. I was hoping there'd be some adjustment knobs on back or inside, but no luck. Dusting is all I can do. Any ideas? Barter available - Graphic Design for service on this TV (Sacramento area). Thanks. [email protected]

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 them in all directions your convergence chips are bad and should be replaced. 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.

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.

This is probably the notorious "light engine" problem that all of these Sonys of this design run into sooner or later. It is usually more expensive to repair that what the TV is worth, sadly. A Sony authorized repair center can confirm this.
