Question about Samsung HL-P5063W 50" Rear Projection HDTV

Constant buzzing even when muted

A few weeks ago, when we would turn on our Samsung HL-P5063W, a buzzing would start. It quickly stopped making noise. Ever since then, it has progressively gotten worse, to the point that it just about constant. Even does it when TV is muted. What is it? I have heard everything from fan to color wheel motor all the way to gremlins. One repair place said I didnt know what I was talking about because I was female...

Racing_babe5, If the buzzing sound is coming out of the speakers while unit is muted, you or qualified electronics technician will need to find out what electronic component (ACTIVE or PASSIVE) has failed and is now passing an unwanted signal (of an audio frequency) into the final audio amplifier circuit and is then sent to the speakers to annoy you!! As a tech, I would solder an appropriate carbon composition resistor of same ohmic value and wattage rating across the leads of the speaker wires just to make sure if the noise is coming out of the speakers. Never run tv with speakers disconnected without having a "dummy" load resistor connected to the audio output wires!!! Risk of damage to audio power amp!!! Me, I wouldn't go through all that! I would just hook my meter up or an oscilloscope to monitor signal levels appearing at the speakers and "toggle" the "mute" button on/off and note what happens. Yes, this symptom sounds like a typical internal dc power supply (filter capacitor) failure that will need a technician to troubleshoot down to component level or do board level swapping to remedy. Good luck with the repair and don't put up with ANY gender discrimination from anybody!! Hope this helped. Tell us what course of action you use to fix problem. Bye for now. 12fixlouie

HL-P5063W Constant buzzing when on or off


The clue is you hear it with the set off, most likely a transformer or coil in the standby power supply, not unheard of (no pun) for this type of part to actually vibrate hard enough to make a unpleasant sound that can be heard.

Troubleshooting consists of finding (listening) the culprit and either replacing the part or in many cases Hot glue applied (some if a small coil or transformer will use super glue on the copper coils) to the exposed wires on the part.

I have Samsung DLP TV 50 inch HL-P5063W


First thing to look at is the color wheel this model uses--usually it will make a high pitched fan like sound but can make a grinding sound also.

If it slows down from the 12,000 or so RPM speed it will cause color issues.

HAVE GRINDING OR HIGH PITCHED SOUND?

L hear constant buzzing even when the tv ( samsung hl p5063w ) is muted. how can l fix it myself


The fault can be that the power amplifier has some errors as it is not controlled by the mute. Possible some capacitor or the power amp IC is defective. you will need to remove the back cover to confirm the fault in the board after checking for visible signs of any capacitor leaks. Use a good multimeter to check the +B voltage to the IC as if the voltage is not filtered the HUM can be produced. the .

Sounds like a bad color wheel. Generally when the color wheel goes bad, when you try and turn the TV on the lamp will ignite for a couple seconds and then turn off. It also makes a rather high pitch squealing noise.

My picture won't show after replacing the lamp


Actually that humming sound was not the lamp, the humming sounds come from color wheels when they're going out, and since the color wheel is part of the light engine system and it's not working, that's why you don't have an image, you'll probably ask your self why, since it's not the lamp.. the thing is that the light engine system is componed by lamp, ballast, color wheel and dmd board, so when one of these doesn't work, there will be no image reflected, because they work together
