It is usually large and black. Its the one with the rather thick red wire coming out of it. The other end of that wire either connects directly to the picture tube or into a distribution block which distributes the high voltage to the 3 picture tubes (guns) in projection TV's. Be aware that this transformer produces high voltage and can store voltage even when the set is unplugged. I hope this helps.

Where is the flybac located in a rca hd52w59


Hello
Flyback transformer other wise called Line output transformer {LOT} is actually a step up transformer, which supplies extra high tension voltages to the guns. It can be locatee on the main printed circuit board. 2_7_2012_5_19_59_pm.jpgJust see the different views of the main board of your RCA TV. You can see the flyback transformer at the left top corner, look like a large black componen; with a ferrite "U" type core goes though it. It is the LOT. Line Output Transformer, otheriwse called as Flyback Transofrmer. OK.

My tv. proscan mod. ps50700 won`t turn on


The PS50700 uses the 195 series chassis. The most common cause of the set not starting up is a shorted flyback (high voltage) transformer. Sometimes a shorted flyback will also cause the horizontal output transistor to short too. These parts need to be tested and/or replaced by a tech familiar with the RCA 195 chassis.

Having similar power problems with my RCA R52WH74, shuts of and turns on by itself and no picture. Replaced the CP150, CP114 & CP120; still the same. What next??


Try resoldering the flyback transformer, If that doesnt solve the issue then the small signal board is most likely the culprit.

Is rca r52wh74 and rca d52w14 flyback interchangeable??


No you will need the 270125 Flyback for the R52WH74 as thats a ITC222A chassis. The D52W14 is the ITC222 and uses the 259296 flyback.they are not interchangeable

RCA R52WH74 turns off 3 times


Hello Kira-chan,

You are going to have to take those capacitors out of the Tv and check them on a capacitance tester. Some digital multi-meters have them, but I would suggest using the LC102 by Sencore That way you can check the ESR, and the dielectric absorption of the capacitor. It is my suspicion that these caps are bad, but should be checked before replacing them.

In addition check the BLUE and RED CRTs for cracks around the neck oy the tube, BE CAREFUL.

I hope this helps,

Thank you,

Concave screen colors in 3d


I have the same tv and just had mine repaired for the same problem just got it back yesterday turned out to be the fl231 fuse blown and the flyback transformer solder points have rings in them. It cost me $211.00 to get it fixed and they said it's common problem and most repair shops should have the part in stock and fix it in a couple of days.

RCA P52937 Flyback Transformer question


The lead going from the flyback to that other device is a voltage divider or splitter as they're incorrectly referred to... To remove the leads press down firmly, twist and then pull up...
