Question about Samsung HLP4663W 46" Rear Projection HDTV

1 Answer

3 lights blink and a loud buzzing sound.

Everytime I try to turn on my tv it makes this loud buzzing sound then it shuts off then the 3 lights blink It does not try and restart it self not unless I try to turn it back on. I took the back off and seen the bulb was getting power for about 5seconds then the bulb shuts off. Not sure whats causing this but. I's funny cause a few months ago when I came home from work someone left the tv on and it was making the awful loud buzzing sound with a picture that was like going crazy. So I turned it off and try turning it back on then that's when it started to happen. So we left the tv off for a few months and I decided to give it a try again. What's the problems you guru's. :D

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.

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.

My RCA 52inch DLP TV has 5 blink red lights and is making a loud buzzing sound. I am pretty sure it's the color wheel, but from your experience, could this be it?


the loud buzzing could mean something is stuck in the color wheel or that it's shattered. Either way, you're going to need a new color wheel, I agree.

TV makes humming noise, lamp light is blinking, does not turn on


Your color wheel needs to be changed. Mine just did the same thing. I changed mine, and the buzzing sound went away, however now my picture washes out with light or yellow colors. The darks look green and purple also.
