Arcing and sparking reported. 2x3mm piece of broken off spark erroded phosphor bronze spring dropped out of the case, on opening. This came from a2 way power socket of size that could probably take mains V but not 2A it would seem, wired to the power-in connector and position under the LCD. Between that and fuse? marking F6602 2.5A on the overlay, a large area of smoke staining. Cleaning off most of the smoke, one 2 land SMD seems a bit pitted and which lump is / was? the fuse , some spark erroded pcb trace, anyone know of a decent pic of this area. off seems a different model, the white block , the 2 wire connector to power socket is the same While at it ,the battery only measures mV , will it recover or some sort of active sw/relay inside?
