Why not replace it with a 4K HD flat panel television to fit the space?

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.

First off you gotta tell us whats the right model and make as you have two listed here and both of these flybacks are avail. trough http://www.partstore.com. The parts are not listed online but get the toll free # or leave a message for them to get back to you. Now A flyback is not a user replaceable part for starters. It is soldered in and theres very high voltage inside these sets even after they are unplugged, and its not adviseable to replace a hi-voltage part in a set, unless you know the issues involved with replacing such parts. Good Luck
