Case secured with 4 x Torx screws underside. Double tab fasteners along both sides centre need leverage to unclick.
White rubber gasket occupies surrounding groove. Unclip aluminium covers, 2 clips each side ends. Unclip LED daughterboard / switch. Bottom aluminium heat sink is stuck to case with glue or tape, prise upwards.
Top aluminium cover has soldered earth wire. (Remove temporarily for convenience).
If no LED's light, check input fuse F1 adjacent IEC AC input socket.
If LED's light, but less than 40v DC output and no flashing GREEN LED, check output stage fuse F2 adjacent red and black output wires. Both fuses wrapped in black heat shrink. Output fuse is common issue. Replace with slow blow T15A 250V ceramic fuse with leads pre-attached.
Why does this last image keep duplicating itself and won't delete ? I give up.
