I got a 42" Panny G10 last november and for about a month now Ive put up with what sound like loud creaks/cracks coming from it. I notice it more in the evenings when its quieter (kids!) and its really distracting when it happens. Its not a constant thing, it can not happen for an hour or so and then happen a couple of times in the next ten minutes. It sounds a lot like some kind of thermal expansion noise. If I squeeze the sides of the panel frame I get similar noises but not quite the same. The actual ones are much louder and sharper sounding. This is my first plasma so I dont know if this sort of thing is normal or not. I rang up M&S today and there is an engineer coming round Thursday morning, I know I wont be able to reproduce the problem so Im not sure what he might do.
