There is a faulty capacitor somewhere in the unit sending wrong voltage. The system will have to be tested with volt-meter or capacitor tester to determine faulty capacitor

Tv makes high pitched humming noise


A high pitched humming noise is an indication of a ground loop, or a circuit gone bad in side the TV. I recommend taking it to a repair shop. This isn't something you can fix yourself.

When my polaroid flat screen tv is turned on humming


Check to see that you're not in SAP mode, (Separate Audio Program) in the audio portion of your menu. Could also be filtering via a bad cap or two in the audio circuit the the hum is a 60 cycle hum because of it. If you have a cap analyzer you could check those also.
Hope this helps!

My TV makes a humming noise and the display on channels that are broadcasted in HD is not working.


the reason for it not displaying HD channels would be the Tuner itself, The humming from the back would be a fan that is dirty from dust or its is given out.

solution for the humming clean out the fan! check fan to amke sure its doing the right RPM rotations per min. For the tuner this would need to be looked at and tested by a Tv repair person.

Constant humming/buzzing noise


I purchased a poloroid tv 3732 in may of 2005 from circuit city, after about 14 months the set began making a clacking sound and humming sound that gets so loud it is unbareable. I have to turn the set off. I have found out I am not the only one with this problem that has a poloroid tv. I had a technician at my home that told me there is a service warranty on these sets because the wrong part was used and the part needs to be replaced.
