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!

Loud pop, dark screen, three blinking red lights

capacitor in the power unit has blown up.
i hope you have a warranty, if not you can call around see if any one repairs these units, you could call the manufactures customer service line see if the have authorized dealers to service there units.
most of the time the cost of labor and parts it mite be cheaper to buy new one, this depend how old this unit is.
check with the credit card you used, did you buy the extended warranty, where you purchase it will have service provider for that unit.

Problem with Sony FD Trinitron WEGA KV-32HS510 32" TV

Blinking of standby LEDs to Sony TVs are fault indications. Form the number of blinks occur at one time, the repairman can get an idea of the faulty stage inside it. According to you, it blinks 4,6 & 7. Just visit this site, It has details about blinking codes to Sony TVs, both CRT based, Flat panels and Plasmas. I can't provide more advice to you, because the number of blinks are not constant. Check the site, and get it.

Turns off and blinks 7 times

The 7 blinks in sony tvs(sony errors codes) usually indicates a high voltage shutdown(tv has exceeded 33k volts) . The power supply regulation and/or the horizontal circuits may be at fault.Unless you have a good knowledge of tv circuitry you might need the help from a local tv repairman. Hope this help. Good luck
Please do not rate this answer(unless it helps) as it is only a suggestion.

Sony FD Trinitron Model: KV-32HS420. Turns on for 3 sec.

Its a problem with the capacitors on the main board. If you open it up you will notice that 1 or maybe two of them have puffed at the tops. Sony will fix this for you for about 200 buxs or if your able to, pull the capacitors yourself and take them to radioshack. You might spend 15 bux tops.

Sony Trinitron XBR, Stand By Mode?

Many of the later model Sony TV?s have a built in self-diagnosis function. If the timer/standby indicator is blinking, this could be an indication of a problem with the unit. The diagnostic blinking will occur automatically with no action required by you to engage it. The timing of the blinking you see would be as follows: two to nine blinks, (depending on the fault), about a third of a second apart, then a pause for 3 seconds, then the two to nine blinks about a third of a second apart again. Here is a list of the problems that might have occurred indicated by the number of blinks. The words in parentheses are those, which you will see for each of these faults on a diagnosis screen described later in this article. Unit is dead, No blinks - Problem in the standby power section. Might check fuse, R607, Q601, IC601, R612 and VDR601 (should show open). Continuous blink once a second, no pausing - No reply from the jungle IC301 (data bus is busy, shorted to ground, or held high), IK video path is defective. One blink - not used for the self-diagnosis Two blinks - B+ over current protection (OCP), unit goes to the standby mode then displays the 2 blink fault. Could be a short in the power supply of any of the circuits. Three blinks - B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672. Four blinks - No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted. Check IC1509, Q1505 Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly. Six blinks - No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately. Check C515 & 516 and the jungle IC, IC206. Seven blinks - High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits. Eight blinks - Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code. Check IC406 audio amp, PS401, and 402. On some projection models of Sony TV sets, this code means that T8005 (flyback transformer), or the associative components in the high voltage circuits are defective on the D board. Nine blinks - Replace D 6116 and D 6301 on the "G" board, do not resolder as this will fix the problem temporary. Or Panel Module Error or Thermal Error. If it is intermittent 9 blinks, meaning sometimes the TV comes on and other times you get flashing, then change the switching regulator on the "G" board or check connections. Make sure the regulator is -12 or -13 (negitive). Ten blinks - Check Q8014 and Q8013 for shorts, leakage, or bad solder connections on the " D" board. If the transistors are bad, check R8051 and IC8005, also on the "D" board.
