If it has been moved or bumped recently the sound you are hearing is the main HT lead that has been displaced. TGhis is a blasck lead with a rubber disk surround at its end that fits into the picture tube. Do not touch without turning TV Off and using rubber gloves to reinsert.

Hello why do I have a loud buzzing noise coming from my umc combination 21 inch television so bad you cannot here program dialogue ?


You need to send your TV Model first, but in general any strange sounds in a TV come from the followings:
1- High ripple in the power supply of the sound card.
2- Bad polarized capacitors in the sound card
3- High noise in the main power supply (SMPS)
4- For CRT tv, weak insulation of the Line Transformer
5- An external source near your TV set which is picked by your TV and amplified.

My 32" Philips LCD TV makes a annoying buzzing


The main cause off buzzing from these sets is the transformers on the psu. This can be solved by sealing the transformers with a sealant spray.

High pitch buzzing.


Hi there
Let's make ur problem a bit clear. "white lines" how? where?
meaning retrace lines with full raster or a single vertical line?
buzzing sound? without even turning the power switch of the TV to "ON" or when u just plug the power cord?
I'll check for schema, mean while can u tell me where the resistor leads to? is it a fusible resistor? if so , to which area the resistor suppliers power?
Regards
Rifaa

Buzzing noise


This might not work for you, but Syntax LCD tvs have a similar problem straight out of the box. To fix it, I had to turn the backlight brightness to full brightness, at which point, the buzzing went away. You might give that a try!
