Question about Samsung Projection Televisions

1 Answer

High pitch sound from 50" projection TV monitor. It's not either fan unit, because that's what it sounds like. I have disconnected both fans and the noise is still there.

    Settings don't have anything to do with this problem. This is a bearing or something. I thought it was one of the fans because it winds down after the power is cut off. I was thinking maybe the color wheel?

Hi-

If its a hi pitch sound chances are its not recognizing the source or signal- try reconnecting cables and setting programs on the projection tv-

Keep us posted- thanks!

    I would agree on that but that's hard to check on too, if the product is within warranty pls call manufacturer, if not then you can have this checked or service. thanks

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?

WHEN I TRUN OFF THE TV IT MAKES A NOISE LIKE SOMETHING IS TURNING AND RUBBING SOUND.


2 solutions for problem. ONE color wheel is grinding. IF high pitched sound is heard. Second bad fan or fan contaminated with dust. Turn TV off unplug. LET cool down ... Using canned air clean all vents on rear of set. MAY also need to remove cover and find the 3 fans inside of set.

Screen suddenly turned off, makes an odd high pitched noise when it tries to turn back on. power button flashes orange


Sounds like there is a power problem if the neutral (return) wire on the power supply has become high impedance (or even disconnected) then you will get a high pitched sound coming from the TV PSU also the voltage that is presented will not be 240V which will give you the same problem.

The orange power button means standby if you fix the PSU then the TV might work again but it may have been damaged by the PSU.

Samsung HLN5065W 50 in. Rear Projection HDTV-Ready


With the back off of the set it will shut off. There is a lever it engages to prevent the set being operated with the back off.

The color Wheel will cause a fan like or high pitched grinding noise. I can tell you where to buy it and also there are on the internet places with written and VIDEO instructions for the replacement in most of these sets.

Put the back on and see if the set again works and still has the noise.

High pitch sound


If the sound goes away when you turn it off, its the colorwheel. If it keeps running for another 1-2 minutes (cooldown) then its a fan. Both are changeable by a technical person, the colorwheel being much more intensive disassembly. Let me know if you need help there.
