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!
