My first instinct in this is flyback transformer. or if it is three tube projector could be a high voltage splitter lines in picture sound like what is called retrace lines ... this is another indication of a possible bad flyback. high pitch sound is another sypmpton of a high voltage flyback transformer problem. WARNING televisions generate potental lethal charge. the device called flyback is used to generate several THOSAND volts. so be carefull if you take the back of any television. along with the flyback the horizontal output transistor possible could have failed. What type of tv is it? model

Every other line of resolution flashes black


the fan like or high pitched sound may be a color wheel--if you unplug the set and remove the lamp you can look at it--any pieces of the colored plastic wheel missing or broken?

Samsung model HLP4663WX/XAA with loud buzzing noise, need to know which part to replace.


See attached photo: you have a bad color wheel----it turns at about 12,000 rpm and bearings in the tiny motor go bad.

High pitched or fan like sound is classic symptom.

The wheel is available on the internet and You Tube has video instructions by model number for replacing it---Google the model number for the part number for your set to locate the part and instructions.

This for most people is a do it yourself job---takes like 45 minutes start to finish.

If color wheel slows too much set will shut down as its speed is monitored and the wheel can even shatter causing shutdown of the set.

My Samsung HL-S5065W will turn on, it makes a humming noise. The picture comes on after a 1 minute or so the screen will go black and the tv shuts down. What could this be?


Hi,It sounds like you might be

experimenting a color wheel problem.The

color wheel is a rotating disc that has a

gamma of colors it spins at high rpms.The

light of the lamp goes through it to create

the colors on your tv.When it starts to go

bad you will hear ,humming,buzzing,high

pitch noises ,you might also experiment

color distortion ,black and white

picture.Here's a link that will help you

replace it:

RCA D52W19B makes high pitched buzz when on


Sounds like a coil is vibrating or a component is bad causing the transformer to whine. Could possibly just need soldering.

Samsung 7178 buzz noise


Is this buzz from the speakers?
Is this buzz from the set itself when the sound is turned down?
Is this buzz a low pitch sound?
Is this buzz a high pich sound?
Does this buzz vary in loudness with the volume control?
Does this buzz change in level from time to time?

You should post the details and the circumstances of use in order to give some idea of the conditions.

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.
