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.

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 turn the tv on ,sometimes i hear a high pitched fan noise.


Hi, bearings in color wheel are about to fail, get it fixed now before the wheel shatters the prisms all over the inside of the tv which of course will then cost you more to fix, video-tek

TV making high pitch sound


Hi, There are usually 1 or 2 fans inside the TV's. Could be worn bearings, or fan blade interference. Sorry, without my electric ear working, I can only guess.

Samsung LNT3253H is making a high-pitched noise


I had the same issue. The tech that came out today removed the transformer on the power supply board, "resealed" it, and replaced it (re-soldered the same part back on) -- the transformer apparently vibrates because it was not properly sealed. BTW, mine was about the fifteenth that he has performed this repair on within the past couple of months -- all 32" and 26" Samsungs. Now, it appears to be absolutely silent.

High pitch noise when tv warms up


High pitch noise is created mostly by a Coil or a transformer,is not easy finding the source if you are not familiar with this type of coil since there many sizes and shapes,the set needs to be on while trying to find wich part is doing it SO if you dont know where and how better call a Technician and you will be safe.
