Buzzing Panasonic lxd70

My first one from JL buzzes as does the 2nd one, so going to get another replacement or possibly upgrade to the lxd700.

Anyone else experience any buzzing, there is also a constant hum, while the buzzing is always in the evenings.

You sometimes get buzzing from the inverters in LCD sets, but Plasma are more prone to it, due to their higher power.

dont know anything about invertors but I thought it was the fans on Plasmas that made a noise

The PX70 range do not have fans

The fans do sometimes make a noise, but they are usually designed to be pretty silent - the buzzing noises usually come from the X-main and Y-main boards, these are actually part of the PDP itself, and drive the panel with it's high voltages (basically a type of inverter, but higher power than the LCD ones).
