The high voltage system has internal bleeder resistors in the form of the high voltage divider that is used to derive the focus and screen voltages. The majority of the voltage will usually bleed off in 30 minutes time. If you would like to feel safer, allow the set to rest unplugged for a day for all but just a very small charge to dissipate. (a discharge then will make only a small "tic" instead of the crack like a rifle) Then disconnect the leads with one hand behind your back and with you not in contact with any metal. Old hands like myself will use a good cliplead and a thin tool to discharge the system while there is a good amount of snap left., slipping the tool under an insulating cap. DO NOT pierce any insulation on the wire or rubber caps, as this will cause arcing in the system later. If you attempt this BE EXTREMELY CAREFUL!!!!!!! Again one hand behind you back. If you were to get discharged on you don't want to have a path across the heart! And it's not for the skittish, the sound tends to make even the experienced like me still jump.

If you find my suggestions to be helpful, please share with us some details so that others may benefit from knowing the whole story. Thank you!

Locating the ''flyback transformer '' on a rca mod #R52WH74


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.

Tv will turn on


leadfoot,
i believe the problem is the flyback transformer. try cleaning by using a small aerosal can. this will either correct the problem or you might have to replace it.

flyback transformer stores energy so i would suggest hiring a professional technician.
