My 16 month old Humax DTRT1000 has been turning itself off usually after a few hours leaving a blank screen and is unresponsive to any commands from the remote. Sometimes it also make a rather worrying fizzing / sparking sound when shuts down. To restore I have to reboot by switching off and on then waiting for the start-up process to restart. Usually this second session last the rest of the evening but last night it shut down for a second time after only 10 minutes. The store where I bought (Richer Sounds) advises a factory reset but this will mean losing all recorded material. Anyone else had this experience and any suggestions please.
