Hi!
I have this broken Eiki LC-XM2 LCD- projector. As I plug the power cord to socket, red "LAMP" led lits and green "READY" led blinks once. And that´s it. Nothing else.. The projector was originally manufactured by Sanyo (not 100% sure) and sold as Sanyo PLC-XW20, Canon LV-X1, Boxlight XP-8t or EIKI LC-XM2 Maybe other brands / model numbers also.. I´v done some diagnostics already: * All fans spin (tested because they all have rpm sensors) * 5V supply seems to be ok. At least I measured it from supply pins of several IC-chips. * PSU electrolytic caps are ok (Fluke 12 capacitance measurement) Here´s what I know of the machine before I got it: * Broke down once before, went to service & came back. Some kind of cap problem in the PSU I believe. Someone had replaced/resoldered all caps on the low voltage side of the psu. * This time (and likely last time also) broke during use. * Lamp is ok. Tested with other unit. Any ideas? Does anyone have schematics and/or service manual for this unit? TIA! - Jiri K. Remove XX if you reply directly. |
