deformation is required. Electrical circuit humming/panel buzzing:
A low level noise is generated from a high-speed switching circuit,
which supplies a large amount of current to operate a product. It varies
depending on the product.
This generated sound does not aect the performance and reliability
of the product.
Do not use high voltage electrical goods near the TV (e.g. electric
mosquito-swatter).This may result in product malfunction.
