18 Mo old Samsung CXM2785TP made high pitched noise and lost power
My set is 18 months old and has had very light usage as it is in a garage apt and has averaged 6-10 hrs of use per week. Today it made a high pitched sound and then i lost power. Neither remote nor TV power button will turn the TV on. Does anyone have any idea what the issue is and if the repair is worth the value of the TV?
Re: 18 Mo old Samsung CXM2785TP made high pitched noise...
The high pitch sound could have been the flyback transformer. check the horzontal output transsitor if is gone the tranfomer is sure to be gone . Tranformers are varying in price are the transistors can also vary you could be looking at around 150.00 plus labour.

Dec 30, 2008 - In my case, the monitor was fine for the first two months. But then started making a buzzing noise... 1) when on, 2) worse when .... my Samsung TV ismaking high pitched noises even if its turned off. I will NEVER EVER EVER ...
I have had the same high pitch tone problem for several months after about 20 minutes of use. It is so bad it's rendered the TV almost unwatchable. I contacted a repair place from Samsung's website. I was told that is likely the flyback transformer. I don't know what it is, but it sounds cool like a flux capacitator. I was told it would be about $100 to fix. However, I have had very little luck getting the repair shop to order the part and do the work.
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.
try washing on hottest cycle it may be the seal in the spray pump somethimes the rinse aid can put a glaze on the seal if that doesnt work you can replace just the front part of the motor( in australia) dont know where you are.
Hello there, You have to specify where the noise is coming from. Is it coming from the speaker or from the back of the unit. SMPS power supply powering your unit create this kind of noise when some capacitor gone out of their value.
Sorry mark that high pitched noise is an indication that the switching power supply has an overload on the outputs. It could be a shorted Horizontal output transformer or transistor or a combo of both. Also could be a shorted vertical driver or output device or could also be a simple cap opened up and is causing a really large current flow BUT if your not a tech i advise you not to tamper with or open the set as you will not "see' a problem or "look" at the open set and find anything wrong! these sets are not user serviceable and can cause you great harm.. So please if the set is this old its probably not worth investing any cash into the repair unless of course it has personal meaning to ya. its up to you to decide Good Luck
