Yoke is the coil assembly that is around the neck (thus the name yoke) of the CRT tube. There is one coil that controls the horizontal sweep and another for the horizontal. As the electrons stream from the guns (or emitters) in the neck of the tube, they pass through the magnetic fields from these yoke coils and get deflected to exactly the right spot on your screen. Pretty rare to have a yoke failure though. Good thing you have a warranty.
Hope Ya Fix It!

Kp-fx532m91 green blinking and followed by red blinks

10 blinks is a high voltage protection. This is why it has a retrace lines on the picture. It can't be fixed by reset or unplugging the set from the outlet because there's a faulty parts inside. It needs to troubleshoot the deflection circuitry to determine which part(s) gone bad. You need to ask for an assistance of a qualified TV Technician because this kind of symptoms is not DIY unless you have an experienced in electronics.

Also, check if you're unit is under warranty period/extended warranty, avail it because the manufacturer will fix it for free. Opening the rear cover will void the warranty.

Picture is turning blue and getting darker with blue dots throuhgout the screen.

That is the optical engine failing. It is the projector part of your TV where the lamp plugs in. The whole engine needs to be replaced it can't be repaired. Contact Sony online, some of their TVs have an extended warranty for this very problem. It is possible that your model is still covered.If so they will help get a repairman out to install it. Parts and labor are covered if still under warranty. If not under warranty that part will be at least several hundred dollars plus labor.

Won't turn on

Although the other response is in much better technical lingo, it sounds to me like the television had a high voltage arc which I have seen on quite a few of the sony big screens lately. Usually, it causes a part on the circuit board, (one of many that were listed on prev. solver's list) to fail. This causes a delimma for the repairman, because when they find the bad part and replace it, sometimes it will pop again causing repeat failure of boards and/or parts on the board. Sony is known for having bad tubes on their projection sets, and it can be a difficult repair even for a trained tech. I suggest calling a sony service center in your area, and get an accurate estimate before deciding if replacing the set is the best idea. Hope this is helpful input, Russmann.

Won't turn on. Green power light blinks for 30 seconds and then red lamp light blinks constantly

If the lamp light is lit, it is likely a bad lamp. If you remove the lamp from the set, you will either see shards of glass in the housing and/or a very cloudy reflector (it should look like a mirror). Be sure to use an original Sony lamp as the replacements are trouble makers. Please be sure to rate this solution. Thanks!

Sony KP-57WS510 57 inch rear projection - Rainbow colors and arching

Same thing happened to me. I had to get it fixed. They said it was a "tube".

Now, my problem (7 months after getting it fixed) is that it suddenly seems a lot dimmer. I'm not 100% sure, and was wondering if there was some kind of diagnostic to run to find out for sure.

Power shutting off and coming back on

The problem is your bulb is going out or malfunctioning. I had this same problem and Sony's repair service couldn't fix it. I posted on another forum and found a great tv repairman that told me that when the lamp is going out or bad that it can cause the tv to do strange things. I replaced the bulb and the problem is gone. Here's a tip, you can replace just the bulb for about half the price of the full lamp assembly. Sony wants $250 but I bought just the bulb for $125 on ebay, spent 20 minutes taking apart the housing to replace the bulb. Just make sure you take note of how the spring is installed before you take the first part off. Other than that, piece of cake.
