Question about RCA 27V520T 27" TV

1 Answer


Have a three week old TV 

 Serial #  RCAHD44LPW62YX1

 Model # F344C600E


Just started that noise. Seems to be getting louder.

Book states it is in its lamp cool down cycle when you hear this, but this is running all the time the TV is on now. It is annoying to say the least.

Hello olfogieo,


This sounds like the IHVT (flyback) is arching and or going bad or the horizontal frequency is changing. you may have to remove the back of the TV and tell me if you see any arching from the flyback.  I would not suggest that you attempt to repair this since the high voltages section have voltages that can kill.

    As I said in my post it sounds like a problem in the high voltage section. Is it expensive to fix? that depends if the IHVT is bad and the set costs about $200.00 get a new set because the troubles you will have are not worth it. If the set is $1000.00 to $2000 then by all means replace the part.


    I hope this helps.

Lg tv humming noise when tv is on

The humming noise is most likely coming from the power supply.

If the unit is worth the repair cost ( Over $100.00 ) you should have it repaired.

If not, deal with the noise until it goes out.

Probably the condenser fan motor is going out they will often make noise for a long time before anyone notices. Get it looked at soon. overheating the compressor on that old of a fridge could spell trouble.

Humming sounds come from the power supply and buzzing sounds come from other circuitry. Most likely a capacitor somewhere.

Finally called a service technician. He said the compressor was bad and needs replacing. Fortunately, I'm in the 2nd - 5th year of my limited warranty so parts and labor are covered. He also said that the FRS26R4A is "junk" and it helps to support his family.

My whirlpool aide by side fridge icemaker is making buzzing or humming noise

Welcome to fixya.
I'm Huuum and happy to assist you,

You said, your ice maker is making a buzzing or humming noise ice maker isn't making much ice. . fridge is about 2 1/2 years old.

This sounds like a clogged water line or a electrical short !
I would get service rather than take a chance on electrical fire.
Or burn up the circuit in the ice maker.

Thank you for giving us the opportunity to advise you.

Humming noise coming from Jennaire built in

is the unit touching another apliance or unit touching it as the contact can produce sound as it vibrates on something else if it is not touching something else then the unit probably isnt level it should havfeet on the bottom that turn round to allow you to get the unit level you will need a spirit level to do this and put it running side to side and get it level then do it front to back and get it level on getting it level the noise should stop if the noise dont stop then it is probably just a noisy motor there is nothing you can do about this as they sometimes are noisy but if noise stops when you open door then the unit is probably not level and opening the door balacnes the weight distribution and levels the unit and therfore stops the sound i would try balancing the unit first or make sure it is not touching anything else hope this solves oyur problem good luck...........................
