The wires don't come off the flyback. You have to take the front cover off where the speakers are. Trace them and unplug them.

SOURCE: Sd Tech. need picture of blown

Hi, I have found you a service and repair manual at the below website, inside this manual, is ALL the necessary facts to enable you to troubleshoot and repair.

Above is a picture of a bad xformer...as you see they are NOT much different that a normal good one. You need to test these units with a meter or a FB tester.
Usually the "Chopper" transistor, The power transistor that"Drives" the FBT, is what fails in the Flyback circuit, and that's what we suspect most when there is NO output from the FBT.
The FBT's don't really fail that often, but they do indeed fail, one must check as said with a meter, on OHMS,and we look for shorts or usually Open circuits, The FBT is wound like an autotransformer and has a common winding, & various outputs.
In any ebvent please download your service manual and perform the troubleshooting steps in there you should be able to sort iot no problem.
Another thing to look for is shorted ceramic caps in the various outputs from thre FBT.

So what's a flyback or convergence option ??. Heck, even a stick-figure Diagram might do the trick. It's nice 2 have folks like ya'll sittin' 'round helpin' each-other out


The flyback is the large transformer that has the thick red wire coming out of it. The solder has a tendency to crack slightly which causes the FL231 Fuse to blow ( just to the right of the flyback) When the FL231 fuse blows the convergence option will disappear from the setup menu and the set will appear 3d with an arced picture. I am attaching a pic that shows the Flyback with a white circle, The FL231 is the yellow circled item next to the flyback11_1_2012_11_47_00_pm.jpg

Is there a diagram online that can show me where the CP114,120, and 150 are located on my RCA M#D52W20


The are tan and next to the flyback and are marked with location numbers right on the board. On that board if one is open (read like a fuse) the set will no longer display the convergence option--there is a kit with 3 parts available for this.

In case you get that board out this model is prone to bad or broken solder connections at the flyback and around it.

I am replacing the flyback transformer


You should post here pictures of old transformer and point out what wire you want to remove, then I can give you an idea what to do as flyback transformer is not in front of me.

if the final flyback is ok ,then check the driver transistor and the voltage in his collector .Probably the flyback transformer is ok.please reply.

36" RCA- loud whine/squeal when it is plugged in, otherwise no power.


The HOT Hortz output transistor has gone home, 99% of the time from a faulty IVHT (Flyback Transformer), very common on the ctc187cl* chassis. The factory Flyback is no longer available, I have had problems finding an aftermarket one to replace it with.

The HOT is a BUH517, but you can also use a 2SD5129. It is the transistor mounted on the siler heat sink with a metal clip rather than a screw, just in front of the flyback.....

If you replace just the HOT, most of the time you will get a rapid arc (27,000volts - BE CAREFUL!!!) from the lower (yoke) post on the flyback. If the flyback is shorted, It may also just burn out the HOT and go right back to "squealing"....

Good luck finding the flyback!!!

Flyback transformer?


Its either the flyback or a regulator. But i would need the model number of your set in order to know for sure. Please reply to this same post with your model number.

Problem


There is no "Flyback transformer" in the LCD monitor "Benq 17" model No. Q7T3". Such a component, a "Flyback transformer" is found in televisions and in Picture Tube type monitors. The red wire of a "Flyback transformer" is where 27,000 VOLTS comes out of to connect to the picture and such a voltage IS DEADLY so never enter a TV or computer monitor unless you know exactly what you're doing. To bring your hand too close to the "Flyback transformer" is to GET ZAPPED, you don't even have to TOUCH that transformer or the Red Wire that comes out of it!!!!

As far as a fuse blowing, NEVER PUT IN A FUSE WITH A HIGHER AMPERAGE RATING: it's there to protect certain components from being permanently damaged. If the fuse is blowing you must find out "why". There's got to be a short circuit in one or more components. Transistors, Diodes and Capacitors are easy to check for shorts. Transistors, Diodes are usually what short out. There's not much more I can say here.

A schematic diagram that shows the voltage on the many components of a running LCD circuit is what you need to find out where volatges should be. If a voltage is missing you must find out where the problem stems from. There are other ways to test circuitry, with an oscillascope and a schematic diagram that shows test points and the wave pattern that's suppose to be present.
