Not sure as to what you are wanting to know But When you re[lace one Yoke you Have to replace All 3 Yokes because they are all wired in series together. SO just guessing 500.00?

I have replaced the flyback, all the bulging caps, a burnt rectangular cap and the HOT and still nothing


If the set had a burnt CL031 Capacitor and its now squealing you may have a broken CRT if not the deflection board itself will need replacement. But I would inspect each CRT neck real good even loosen the yoke as often they will crack right at the yokes clamp line.

The tv is froze and makes squeaking noises, wth? Oh by the way it is a Westinghouse


First, make sure it is not coming from the loudspeaker itself. If it is, then we are looking at an unusual electronic interference problem rather than simply mechanical vibration.

In most cases, this sound, while annoying, does not indicate an impending failure (at least not to the set - perhaps to your mental health) or signify anything about the expected reliability of the set though this is not always the case. Intermittent or poor connections in the deflection or power supply subsystems can also result in similar sounds. However, it is more likely that some part is just vibrating in response to a high frequency electric current.

There are several parts inside the TV that can potentially make this noise. These include the horizontal flyback transformer, deflection yoke, other transformers, even ferrite beads in the horizontal deflection circuits. In addition, transformers or chokes in the switching power supply if this is distinct from the horizontal deflection circuitry. Or even a portion of the sheetmetal used for shielding if in close proximity to a magnetic component
If you are desperate and want to check the inside of the set:


Using appropriate safety precautions, you can try prodding the various suspect parts (flyback, deflection yoke, other transformers), even lowly ferrite beads, with an insulated tool such as a dry wooden stick. Listen through a cardboard tube to try to localizing the source. If the sounds changes, you know what part to go after.

Once you have located the guilty party, some careful repositioning, a strategically wedged wooden toothpick, or a dab of RTV silicone or hot-melt glue may keep it quiet. Where the yoke is the guilty party, see the section: Reducing/eliminating yoke noise.

It is possible to coat the flyback transformer, but this is used mostly when there a loose core or windings and you are getting not only the 15,735 Hz horizontal (NTSC) but also various subharmonics of this. This is probably acceptable but may increase the temperature of the flyback.

A replacement flyback (or whatever part) may cure the problem unless it is a design flaw or manufacturing quality problem. However, the replacement part could be noisier. You really do not want to replace the yoke (aside from the cost) as convergence and other service adjustments would need to be performed. Other transformers can be replaced.
Hope this sheds a little light on the problem
You do not have other speakers right next to the tv??

NOTE: IF YOU DO NOT HAVE ANY ELECTRONIC EXPERIENCE THEN GET SOMEBODY WHO HAS EXPERIENCE WITH TVs TO DO THIS. THER IS 32000 VOLTS INSIDE THIS TV AND IS DANGEROUS WHEN THE BACK IS TAKEN OFF. THE RED CUP ON THE BACK OF THE TELEVISION TUBE WITH RED WIRE ATTACHED HOLDS THIS CHARGE - KEEP KEEP AWAY FROM THIS

RCA 32V434T TV just stopped working. No picture. We hooked up another TV and it worked so we know it isn't a cable or cable box problem.


You should take the unit to a repair shop for an estimate. The problem could be simple or more complex and costly. I would take this opportunity to upgrade to a newer set as repair cost should be in the 60 dollar range.

Triniton tv no longer working standby light blinks seven times. why is it on standby?


Could be a fault in the powersupplym could be a flyback issue it will need to be evauluated to see what is the cause now most shops will tell you what it is without charge that way you can decide to repair it or replace it I am telling you it could be a power supply issue or flyback I will need to look to rule it out but at least you know what the problem could be and determine the cost of repair. please do click the end session to your right,

When a push the power my tv do not want turn on only hear a click noise


This usually indicate a problem with the flyback, or the horizontal output transistor. Most TV problem is not repairable by the user, because of it's complexity. If you like reading, and honestly like to learn on your own, it is not so hard to learn to fix electronic device such as TV. Unfortunately a TV is not something you can look at and figure out how it works. I would suggest start by reading electronic books, preferably the ones with projects to help you learn how electonic device are put together to make a working circuit. The most I can help you with is look for the horizontal output transistor it is square with 3 pins, and is mounted on aluminum heatsink to dissipate heat. One of its pin would be connected to the flyback and the horizontal yoke.(The yoke would be the copper winding on the neck of the tube) be careful you don't touch the thick wire from the flyback to the back of the tube because a tv tube can carry large amount of lethal charge even if not plugged in! Take that transistor out of the circuit and test it with an ohmmeter. Set the meter to "diode" with the transistor facing you. the first pin is the base. Connect the red wire to that then the black pin should read around 0.4 voltage drop it maybe a little highe on the other two pins.. If you get a reading that is low it is shorted out. Note tho that some horizontal output transistor have a resistor connected to the first, and last pin (base emmiter junction) then it gets confusing. If in doubt just replace it. The cost of a horizontal output transistor is around a few bucks. Make sure you buy two of them! If the TV turned on after you raplace it but later failed again. You have to replace the flyback too. This time use your spare transistor along with a new flyback, which cost from 20- 50 dollars. Hope this helps.

Bearing on 4WD front differntial drive shaft yoke


In short yes, the bearing is pressed on the pinion gear, the only way it will come out is to remove cover on housing and pull carrier with ring gear out, and also yoke that drive shaft bolts to, then pinion will come out, there is also a crush sleve that will have to be replaced when it goes back together it goes over the pinion gear, thats for backlash ajustment when you tighten the pinion back in the housing. if you plan on doing this yourself you will also need a dial indicater to set the backlash. If you want my advise take it to a shop to have it done, if you don't get it right it could end up costing you alot more than if you took it someware and had it done.

Rca d40w20 still wont work even after a new flyback was installed


check continuity from the connector for the horizontal yoke (red and black wires), to ground, if you have continuity one of the ground ******** the crt's is touching the yoke.
