Hard to say. you may just need new convergence ICs. Does your set work and just the convergence controls dont work?

Red and green separate about 1.5 inches apart on left side of screen

Convergence chips can be purchased as a kit for these types of tvs. (G**gle it). The repair is very easy with the kit. Usually comes with two ICs and a couple diodes depending on the kit needed. Just solder them in and you're fixed

Also, you may need to do some minor alignment on your tv once you get the convergence kit installed. This is done on the little small box with phillips head dials (one for each color of tube)

Try going to and type KDP-57XBR2 in the search catalogue box. There are three service documents for you there. They take PayPal or credit card. I have used them before and the documents can usually be downloded within a day if not immediately. Hope this helps.

My sony kdp-57xbr2 57%22 hdtv turns on and off

The fail safe circuit is protecting your TV You have a voltage drop or open citcuit in one of the components eiuther in the power supply or on the video display boards. Dont keep truning it on in the hope that it will right itself. The opposite may be the case. In fact it can catch fire if you force it to keep trying to fire up... it literally will.

Get a tech to examine it and effect repairs, these problems are not DIY if you have no skills in reading circuit diagrams and handling high tension power and radiation ( which are both present in these TV's.

Est cost currently may be in the $300 region.

Convergence problem

One or both of the convergence IC's are bad and has blown one or both of the fuses. Pull off the front speaker grill and remove the cover, loosen 2 brass scews holding the aluminum frame work, lift it up and out. Inspect The convergence IC's and the soldered connections to the board, check the fuses on the board. Replace both IC's and the fuses.

Won't turn on.

My Sony KDP is blinking 6 times. My guess is the blinking is a troubleshooting code. We just need to located the chart to describe the blinks.

2 Answers turns on briefly...solid color screen for a second...then blank?

I had the same problem about a 8 months ago. I searched online and found that there is a problem with one of the color guns. They need to be replaced. I don't remember where I found the information, but there is a number or something to call for this problem. I think that my authorized sony repair man knew of the problem, there are other models that have the same problem. Anyway, sony replaced all three guns in my tv FREE of charge, and my tv was no longer under warranty. They did all repairs and fixed my tv.
