LG TV Making Bad Noise

Starting yesterday our LG 42LC7D tv is making a horrible noise. We can hear nothing but the noise no programming audio at all. The noise reminds us of a plastic propeller gone amuck. There are no special sound system installed just the speakers that come with the TV.

The noise you hear must be from its back-light inverter board. The ferrite core in the inverter transformer may make a high whistling noise and will be annoying. Contact any technician. It can be stopped by gluing. But is a skilled work.

My LCD TV's audio is making a loud intermittent static buzzing noise.


A test you can make is remove most of the gear that is connected and start with just the cable and no box connected--run to see if issue happens-

Add more equipment until issue appears again--try this way to see what unit is causing this---if nothing but a DVD connected and it does it--its in the set--if not a time consuming thing but only way to see which piece of the equipment involved is the problem.

LG Plasma TV has speakers fizzing in short bursts, cant hear any audio


Yes I believe you have a hardware failure in your audio amp IC. In some cases, a speaker will cause all the audio to distort, but its very rare for a speaker to cause this issue. If you just got it, you can return for a quick resolution, or contact a local repair center for a new main board replacement.
