I just moved my new Panasonic DMR-ES20 DVD recorder into another room, but when I plugged it in a 'crackling' noise came from the unit, followed by a slight smell of burning. After this the words 'self check' appeared in the front panel for a few seconds followed by the standard display. The machine still works, but I've noticed that the fan (at the back) is no longer working. So, does anyone know whether the fan only cuts in after some time or is it always on? I'm pretty sure that before it came on as soon as the unit was powered on, but I'm not sure. I suspect I may well need to return my new 'toy', which will be a pain because I bought it online.
