SOURCE: High pitched noise

I am about to post a in depth guide about how to fix this problem. It's because a capacitor inside the TV has blown which causes the buzzing high pitched noise. It's really easy to fix however and only costs about £1 / $2 to sort out.

You can read a similar guide here http://www.fixya.com/support/r741402-polaroid_flm_373b_lcd_tv_black_screen but I will shortly be uploading a guide on the buzzing problem!

SOURCE: high pitched noise from inside the TV when picture comes on

Hello randapaint,

This might be from the IHVT (Integrated High Voltage Transformer), or more specifically a short in the IHVT causing it to arc, producing the high pitched whine, you are hearing. Take the back off of the TV and try to detect where the sound is coming from, more then likely you will notice it coming from the section that contains a large component with a large red cable coming from it, to the top of the CRT (picture tube). Replace the IHVT (with the exact same model) if it is bad.

I hope this helps,

Thank you,

Shuttle83

SOURCE: High pitch noise coming from the tv.

I suspect you have a bad set of capacitors in the control module. This problem usually starts out as a high pitched noise but can lead to the TV not turning on. Please see the link below, posted by StivO. It gives step by step instructions on how to replace the capacitors. This is a very inexpensive fix.

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.

Proscan 40' 40LC45S has a high pitched hum when it is off. Sound goes away when TV is on.


Same problem here, there is a high-pitched sound in standby. As soon as the light turns blue and the TV is on it's gone. I actually exchanged this TV three times at Best Buy but all the models made the same buzz in standby. I was told that it's normal and in the store you can't hear it since there is too much humming from other TVs around. The power is transformed down to a minimum, just for the remote controls, internal clock etc. and this causes the buzz, like when you dim your lights at home. I hooked it up to a surge-protector for clean power and just switch it off over night. During the day it's hard to hear anyway. - Again, since this is my third (!) Proscan 40' exchange I can definitely say that this is normal for this model. I was just surprised that nobody mentioned the same problem so far on the Best Buy reviews.

All three lights turn on like normal and then nothing


Depending on the pitch. humming noises are either a motor ie: fan motor or if it is very low a defective capacitor . Since you have the yellow band and the high pitched beep my fist thought is somthing defective in the power supply. Take it to an authorized servicer.
