RCA D52W19 Flyback Transformer

My RCA TV has been making wierd buzzing noises that were consistant with severe screen flicker...cuirous i took it apart and found a 'voltage leak' on the red (assuming H.V. Lead) off the FBT i am looking to find a new transformer with leads on it but have been unable.

so what question is i need some help with safely removing any stored voltages within the FBT circuits. and how to terminate the H.V> cable to prevents arcing from the wire to the transformer body......any other information will be greatly appreciated.

This transformer does not come with the hv lead,if the arch is coming from the side of the transformer,cut the side of the plug were it goes into the transformer and the lead will come out,there is no voltage stored on the hv lead after the set is unpluged for a few min.,the transformer you can get at any rca repair center.

You have a bad flyback transformer. This is a common problem that eventually goes bad in the ITC 222 chassis. You have to get the model number with the code at the end of it after the /. And sometimes you must have the numbers from off the flyback itself. Try to contact MCM electronics for the flyback at 1-800-543-4330. First see if they can match it with the model number with the code after the /.

I have hdtv rca d52w19 green power lights shows


Hello Chris this problem is coming from your high voltage circuit which consist of the flyback transformer and the horizontal output circuit, the most common problem when it is acting this way would be bad soldering on the flyback transformer or defective transformer but keep in mind it can also be caused by the horizontal circuit or a faulty lamp as well can cause this problem, what i would recommend is to have a tech come out to service your tv set this should not be an expensive repair since most of the time it is just bad soldering on the flyback thank you hope this helps.

The flyback transformer is super high voltage. Have it checked out by a shop, don't go near it. TV's can hold a charge for days.

Need to know how to install a flyback in 2004 52 in RCA tv.


First and foremost, disconnect the power cord from the mains.
Next, after having removed the back cover from the set, discharge the tubes' residual high-voltage to ground using a suitable tool.
Access to the transformer is pretty much staightforward here.
A few hardware removals and you can then get to the board and transformer..
Mark, then remove all leads that go to the unit.
INstallation is the reverse of removal.
Be sure to replace the driver device, just to be certain...accordianman
