the base to emitter of the hot will read short on a diode checker/test on ohms it vairies but typically about 50 ohms.e to c, or b to c should have very high resistance. unsolder the collector of the hot. make sure all solder is gone. now test the ohm between your tuner ground & the pad of the hot collector it should read open.

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...

The wires don't come off the flyback. You have to take the front cover off where the speakers are. Trace them and unplug them.

Flyback transformer


A flyback transformer is one of the more expensive components in a projection TV. If there is no clear reason, such as a known power surge, you could well replace the flyback transformer again soon because the root problem was elsewhere.
An OEM transformer is not necessary but you might have trouble convincing an authorized factory service technician to use anything but the original manufacturer's parts.
As with many of today's electronic devices, if it is more than a year or two old, you will find the new products cheaper and with more features. The next generation of projection TVs will use lasers and scanning will be done with optically controlled micro-mirrors - no flyback transformer required.

There is a hissing noise in back of tv and picture goes on and off zenith d36d51


Hissing noise and picture on and off means faulty flyback transformer, it has a small crack and voltage is leaking out, replace the flyback, if tv still not working replace horizontal output transistor (broken flyback could blow the transistor).

TV Just Started Making a Humming/Buzzing sound


Replacing a flyback is not something I would suggest for anyone with no electronics experience. Second, lets see where the noise is coming from first. Take off the back and listen to the noise. The flyback will be at one end of the large red wires that go to the tubes. Sometimes the connection at the tube is not 100% and the noise comes from there. BE CAREFUL - there are high voltages going through this red wire that can be dangerous even with the set UNPLUGGED!! IF the noise is coming from the connection at the tube, with the set unplugged, carefully turn the rubber cap back and forth touching only the rubber part with one hand. Put the other hand in you pocket while doing this.

If the noise comes from the flyback side, if you can solder, again with the set unplugged, try resoldering the pins on the transformers. That may resolve the problem.

Keep me posted.

Wont turn on smell burning


Can you remove the rear panel and check if the hissing is coming from the flyback? Which is a large transformer with a large red wire coming from the top of it? If so can post a link where you can get a replacement their not exspensive and their easy to replace. If its not coming from the flyback post a picture of where the hissing is coming from and I will identify the parts for you, But I feel its the flyback due to the hissing. respond to this same post so I have your correct model number when you reply.
