[QUOTE="easysat, post: 438303, member: 175305"] I got the box working again by resoldering some joints on the main board. The dodgy joints were on the main power supply lines: the +3.3V, +5V, etc. supplies are routed from the PSU connector via tracks on the component side of the board to ferrite beads. On my DRX550, the ferrite beads weren't very well soldered as no solder had wicked up through the hole. All the current was passing through a plated hole down to a pad on the solder side to which the lead of the ferrite bead was soldered. I suspect an intermittent contact in the plated through hole was the problem so filling the hole with solder and making sure the leads were well soldered to the pad on the component side cured the problem.
