Graham thanks for the reply. The automatic standby time is set to max, which is 12hrs. On my desktop if I remember correctly, the smart fan runs slow speed, then when required fast speed. The fan on this humax does not run at all. A number of months ago I had an issue with this Humax, cannot remember what the fault was, think it would not switch on, also some problem with fan as I removed the original & fitted another. Have now refitted the (h) fan, and played the film for 3hrs. Both the MBO & HDD very hot. That’s whats its switching OFF. I’m sure months ago it was running. My (H)9200 fan runs as soon as the unit is turned on.
Still has anyone have any further ideas or thoughts on this subject.
