Do you hear noise from the back part of TV? (Fan noise)


Is there noise in the speaker or backside of TV?.


How to fix

- Noise at the backside of TV

① When you initially use LCD product, it generates a lot of heat so the fan rotates to cool off. And that makes the noise. Even though you turn off the poawer, it can still create some noise for a certain period of time.  

For the products before ‘05, some models are equipped with FAN. Products may have fan or not depending on the size of the product and model.

② For products with hardware for time machine, it creates noise when operated.

When you connect external hard disc, it can also create noise.


- Noise in the TV speaker

① When using peripherals (Set-top box, DVD, Bluray, PC, Game console, etc.), cable noise or peripheral noise can be heard from the TV speakers.  

Check if you still hear noise after disconnecting cable of peripherals.

After disconnecting, if you don’t hear any noise, check the peripheral or the cable.
