Sony PSP 3003 plaything
Arcing and sparking reported. 2x3mm piece of broken off spark erroded
phosphor bronze spring dropped out of the case, on opening. This came from a 2 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. http://www.llamma.com/PSP/repair/ima...se/Td-Fuse.jpg off http://www.llamma.com/PSP/repair/PSP_fuse_repair.htm 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? |
