Question Panasonic TV noise in right channel.

Yesterday our TV started to put out some kind of noice from right speakers. It's a Panasonic TX-P42S10E. I've tried to pull out connectors, switch source, mute speakers and so on, without any difference at all.

Does anyone have a nice theory about what happened?
10 years old so maybe a Cap in outputstage?

This has a class d output stage;C1AB00002875 and can produce white noise that is uncontrollable.
If it is not adjustable with the volume control, replace this chip; IC2301 after checking the decoupling capacitors and supply voltages.
Page 12.14 in the service manual.
