Toshiba HD ready TV ct 90158 makes high pitched sound


A high pitch sound can be a capacitor losing power it would sound a bit like a fire work. most have back up on the board but it put more pressure on them the more times you use the tv. would check them and replace. all of them can be 5 in a row in some models.

Samsung dlp tv HLP5663W makes loud noise


Yes, the set uses a color wheel and the lamp faces it.

The wheel turns at over 8,000 rpm and is well known for this problem=bearings in the tiny motor go bad.

The high pitched or fan like noise (classic description) is this part.

Sooner or later the wheel (plastic colored segments) will shatter and set will shut down lamp and not operate---set monitors the speed of the wheel so if it slows down or stops it knows.

The part is readily available on the internet (Google the model number with "color wheel").

This can be a do it yourself repair and You Tube has video instructions for replacing the wheel by model number.

There are two common pitfalls to avoid which the instructions that come with the replacement part usually do not mention---if you decide to do this repair let me know and I will explain.

The TV is making a very high pitched noise. The longer it is on the louder it gets.


Easy repair with some Super glue.Must take the tv back cover out.The FBT-the big block of plastic with a red wire with a cap hook to a CRT(tv tube).It have a high voltage gap going through a "3 inches paper clip steel bar on a FBT the big black plastic block.Put some super glue on that "3 inches paper clip steel bar on that big black plastic block.Should stop the high voltages gaps through that "3 inches paper clip steel bar causing a high pitched noises.

Hd tv makes a hjgh pitched sound whats wrong


Hi, the high pitched sound is coming from the coils or transformers on the power supply.
you can isolate the noise by removing the back and with the set on press gently with a plastic handle/item on each coil till you stop the noise. , you will probably have to replace the coil or the whole power supply, but sometimes you can tilt it over or secure it with silicone and it will stop rimging.
please click a thumbs up it this helps solve your problem

TV making high pitch noise, stop working.


It must be the horizontal output transistor, it maybe short circuited. A short in flyback.

High Pitched Noise


most high pitch noise comes from the anode conection on the picture tube thats connected to the flyback anode cap thats mean there is a high voltage leak,to stop the noise you can discharge the high voltage take off the cap and clean with alcohol.if the noise continue.you will have to put some red or clear silicone both the cap and tube stick together leave to dry for about 2 to 4 hrs.this will eliminate the leaking.good luck.
