horizontal banding in noise?

Can someone with an xh-a1 close their iris entirely (or put lens cap on) and set gain to 36db ... the noise on my unit is a grey and noisy, but if I leave the unit on like this for half an hour, the image gradually gets more and more "banded" and stroby .. as in, strobing horizontal noisy lines, like analogue interference I suppose. This increase in visible "banding" patterns seems to correspond to the bottom of the A1 getting warm .... As it heats up (and gets worse), it gradually becomes slightly apparent in lower and lower gain levels ...

Is this normal? Or should I return the unit?
