Need a flyback transformer - JVC AV-48WP30 48" Rear Projection Television

They often begin buzzing when the oil inside them gets old or evaporates from a cracked housing. It needs replacing however be very careful. Flyback have 50000 to 100000 volts in them even when the tv is off. There is a safety discharge procedure however if you are not familiar with replacing a flyback do not attempt it yourself. FLYBACK TRANSFORMERS CAN SEVERLY INJURE OR KILL YOU.

Throw the set in recycling and buy a new set, its not worth repair, the part would be close to 100 bucks if it was available

the flyback transformer or the Box cap CL031 is arching and will need replacement the flyback is most likley of the two. You can get flyback transformer with instructions from www.tvrepairworld.com

Contact Philips directly. They should be able to get you the part, even if they have to get it from another repair shops. Many repair shops purchase their parts from factory authorized distributors, not from the manufacturer. The flyback transformer powers the tube-it can be extremely dangerous to work on-EVEN with the tv off, they contain a lot of power somethjing like 50,000 to 150,00 volts. It is not fun getting shocked by one of these as many techs have been knocked unconcious by them. If you do not know the proper procedure to discharge a flyback then leave it alone!

There is a little loose sleeve at the transformer. It can be pulled out, but it is best to squeeze the sides through hole on each side of the terminal to remove the sleeve. The wire just comes out with a small pull afetr the sleeve is removed. Good luck.

You should post here pictures of old transformer and point out what wire you want to remove, then I can give you an idea what to do as flyback transformer is not in front of me.

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!!!

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.

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...
