Why is my Panasonic plasma TV buzzing?

The buzzing noise from your Panasonic plasma TV can be attributed to a few possible reasons. One of the most common causes is the electrical components within the TV that regulate the picture and sound. These components can produce a humming or buzzing noise, which can be more noticeable when the TV is not in use or when the volume is turned down.

In some cases, the buzzing noise can also be caused by an issue with the power supply or capacitor, which can lead to electrical vibrations that produce the humming sound. It’s essential to identify the root cause of the problem to determine the best course of action to fix the issue.

Is the buzzing noise normal?

While some level of humming or noise is normal for plasma TVs, an excessively loud or persistent buzzing noise is not normal.
