If is is the fan it is because there is another part they needed to put in to keep the noise from the wheel barings coming through...there is some kind of kit ...i know cause i needed a new light engine and notice no noise from the fan... repairman said they now come with a kit that surpresses the fan noise.

The buzzing noise would normally be either a fan or color wheel that is failing.

I have a samsung hln437n and I have a loud, high pitch buzzing noise which stays on all the time. It sounds like it is coming from the lamp. Any idea what the problem is?


Could be a slightly loose lamp connection and/or slightly loose lamp module - especially if you
have big trucks or railway tracks near your place (like me). Try powering down the TV set, use the
instructions that came with your TV to remove the lamp module, then simply re-install the lamp
module (also known as "reseating the lamp module").

If the buzzing noise persists, then
its coming from a component near the lamp (such as the power supply).
If there's a transformer in the power supply that's buzzing, then its about to fail.

MY HITICHI 50V500 HAS TAKEN LONGER to come back on after turning


The high-voltage transformer (same as power supply) is faulty. It is very common in todays electronics. The old one will have to be difused of all power with difuser. Then it will need to be soldered off and new one soldered on. You can get them at tigerdirect.com, shopjimmy.com, or partstore.com and others.

Toshiba 36zp18q buzzing noise.


Humming sounds come from the power supply and buzzing sounds come from other circuitry. Most likely a capacitor somewhere.

My Hitichi tv will not turn on. When the power button is pushed, the lights come on as if it was going to turn on. Then, the lights begin to flash as if the tv was turned off. After the lights stop...


This is known to happen. You could let it cool down for an hour. If it still persists, then it will need to be fixed.
You can also try unplugging the tv set for at least 4 hours to do a "hard reset"

Buzzing


The noise is caused by dust on one of the toroidal transformers(usually a round looking thing with wire wound around it). Go to the back of your television and try and pinpoint were the sound is coming from. Turn your television off and blow it out with compressed air if it is close to air vents in the television. If you cant see it you might have to open your television back panel.
