Is it 3 sets of 2 buzzes about 15 seconds apart ?

or a continuous buzzing ?

Hi Charles,

Sorry for the late reply, I'm offline upon purchasing my service.
You have said that you can hear a low buzzing sound before the unit gone to subsequent shutdown and the lamp blinks green(meaning that the unit try to turn on the lamp for consecutive attempts but not generally mean that the lamp itself is faulty.) and the temp led light come on.

As a matter of fact all the information you have mentioned linked to the symptoms you've encountered right now. A low buzzing sound might be caused by faulty FAN inside the unit that trigger the error code (blinking of the standby/temp led light) and turns off the unit automatically due to thermal protection circuit.
However, the technician might be true also that the buzzing sound came from the faulty color wheel. To confirm it, you have to verify where the buzzing sound came from. Color wheel is in front of the lamp assembly. Faulty color wheel can produce the same symptoms you've encountered right now but most of the time, it shows 3 blinking led light at the front panel (Timer, Lamp, standby/Temp).

I would advice you to open the back cover of your unit, fixed the lamp door safety switch with the tape to make it in closed position( if it is on open position the unit will not power up), and then turn on the unit and observe the fans if will spin or not, and check also where the buzzing sound came from before the unit gone to shutdown.
I've suspected that the fault came from the fan based on the led light flashes. Please let me know what you will discover after following the steps above to verify where the exact fault came from. Also, let me know the exact status of the led light at the front panel, (Timer, Lamp, standby/Temp ), which of them lit solid/blinking, it will help us to narrow the caused of the symptoms.

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.

Burned out lamp?


First. Turn on the set and see if the Lamp Illuminates, If so then you have a bad Color Wheel. If the Lamp does not light up, you have a bad lamp.
Take out the lamp and look to the center of the lamp. If you see broken glass inside you have a bad lamp.

My samsung 42 inch hdtv is making a buzzing noise


First. The whirring or buzzing sound you hear is the Color Wheel and it needs to be replaced. Second, since I do not know when and if the original lamp has been replaced it is a good idea to replaced the lamp. The bad Color Wheel is the one causing the set to shut down.

Hi,Sometimes its something simple.Did you close the door cover,it has a switch that wont let lamp power on if its not pressed.Did you reset the lamp timer? you can do this by unplugging the tv wait 5 min and plug it back again.Any strange noises like clicking or buzzing sounds? If you heard clicking it will be an issue w the board that powers the lamp its called the ballast.If you heard buzzing it could be an issue with the color wheel,which is a small disc that creates tyhe colors on your tv. Last question did you get the Original Philips lamp or a generic? If you got a generic send it back for testing or get refund and get yourself the original.Email me if you have further questions at r2d2repair@gmail.com have a blessed life!

Hi,do you hear any strange noises? if you heart clicking or like wanting to turn on it could be the ballast that's the board that powers the lamp.Do you hear buzzing,whirling,or high pitch sounds?If you do it could be the color wheel which is a little disc looking that when the light of the lamp goes through it creates the colors on the tv.This are the most common failures on samsungs.

No picture or sound after replacing lamp


Possible bad color wheel...

Pull the lamp out & look inside where the lamp sends the light-

does the color wheel look defective? If so,replace it.

Or, the lamp ballast may be bad.After that,usually replace

complete engine.
