Question about LG 32LC7DC 32 in. LCD HDTV

New 42LG30 - 42

My new LG 42" LCD TV is making a buzzing sound that has become really annoying. It started a couple of days after I got it. The only way that I've figured out how to reduce the noise is by turning the backlight all the way up to 100. Even after doing this it still hums when the screen goes all black.

Is this a common problem with LG LCD TV's? Should I return the TV and get a new one, or is there a way to fix this?

Please let me know as soon as possible

This is probably a defect in the backlight inverter circuit. The transformer may have a loose winding or something in there is not cycling off or on properly. If you can still collect on the warranty, do so.

Tv making loud buzzing noise


A common cause are failure of decopling capacitors in the audio section, and or the circuit board power distribution that feeds the audio board. Most of the capacitors are surface mount components. The standard fix is to start by changing the circuit boards that have the defective parts.

If the set is under warranty, call for warranty service. Out of warranty service is expensive for these TV sets.

LG LCD TV - Buzzing Sound and Faint Horizontal Lines


From your description, the sound you are hearing is the inverter(s) that drive the back light for the LCD screen/module.
The inverters mounted on the back side (one lower right and one left side) of the LCD screen/module. They are under the sheet metal cover/shields.
The inverters are going out and or the LCD screen/module is going bad too.
That LG TV has only a 1 year on parts and labor from the date of purchase, but you could call LG and ask for their help for such a new TV. They might do it under a warranty, for little or no cost to you.
I hope this information has helped you.
Good Luck.

Hi!

I have seen this before in a lcd tv I worked on! My problem was some bad caps (capacitors) on the power supply board. They will look bulged on the top an may be a little leaky (brownish stain). But also check the signal board (rca s-video etc... inputs). My thought in this was a bad cap was producing a harmonic, causing the speakers to squeal! Good luck, I hope this is helpful!

Phillips 32" LCD TV, Sound through TV speakers has a buzzing noise which is steadily getting more aNNOYING AND LOUDER.


We are having the "buzz" problem with our new 42' Phillips LCD too.

We do not have a sound system yet...but have read they have the same problem, so I won't assume when I get a sound system it will go away. What I did do for now...and it helped..

Go to the SOUND portion of TV menu
Choose EQUALIZER
Turn down the two FAR RIGHT columns, they are the treble. It helped us.

The plasma panel in most cases exceeds the cost of replacing the TV. There is also the issue that they tend to use different versions and makes of panels in these sets. Some panels are made by Samsung and some are made by LG. I would start shopping for a replacement TV at this point.

PEOPLE, YOU NEED TO GO BACK TO THE STORE, BUY THE SAME TV AGAIN, SWAP THE TV'S AT HOME AND RETURN THE "OLD" TV IN THE "NEW" BOX WITH THE NEW RECEIPT. IN THE CASE OF TOO MANY RETURNS, HAVE A FRIEND, MOM, DAD, SISTER, GIRLFRIEND TO BUY ONE FOR YOU AND DO THE SWAP LATER.
NOTE: I REALLY HATE DOING THIS TO THE STORES, BUT IF YOU PAY FOR SOMETHING IT SHOULD LAST LONGER THAN 30-40 DAYS. PROBLEM SOLVED! :)
