Flyback transformers rank about a 5 or 6 on dificult to repace.. depending on the model of tv that you are working with.. the rca itc222 can be difficult.. dependend on your soldering experences. To replace this one you have to pull the chassis tray up and out to get to the bottom... unsolder the pins ussally a vacum desoldering tool is required because it is important to remove all solder from the pins..then gently pry the clips that hold it on the board... this is where you can mess up unless the pins have be completly solder free you can crack the board... NOW the hard part... removing the wire from the flyback.. if the flyback is the type that the wire comes out. the wires will eather have a clip around the large wire or you will have to go to the other end of wire and pull it out from the splitter. eather way this wire is firmly in an will require gently but extremmly firm pulling to get out.

Picture on Samsung TXL2791F gets smaller after a few minuets


The horizontal output transistor that drives the flyback transformer overheats now. There might be other reasons too for this fault. If the flyback transformer has any internal winding short, this transistor will overheat.
Just replace the horizontal output transistor. Check its heat. If the newly replaced transistor too overheats, replace the flyback transformer.

TV HARD TO TURN ON POWER KIGHT TURNS ON AND OFF THREE TIMES THEN YOU HAVE TO WAIT THEN PUSH BUTTON AGAIN


Check circuit board with the flyback transformer(the transformer has a thick red wire connected to the top of it)for bulging capacitors. Capacitors are the ones that look like little cans. If you find any then replace them. Also, resolder all the points at the bottom of the flyback transformer. This should fix your problem. If not try using a blow dryer and heat up the back of your t.v. for about 5-10 minutes.

Flyback transformer


A flyback transformer is one of the more expensive components in a projection TV. If there is no clear reason, such as a known power surge, you could well replace the flyback transformer again soon because the root problem was elsewhere.
An OEM transformer is not necessary but you might have trouble convincing an authorized factory service technician to use anything but the original manufacturer's parts.
As with many of today's electronic devices, if it is more than a year or two old, you will find the new products cheaper and with more features. The next generation of projection TVs will use lasers and scanning will be done with optically controlled micro-mirrors - no flyback transformer required.

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!!!
