Dear Sunny,
I checked the attached log file, at the first line it mentioned Main fan error.
Did you check main two fans on the back, above the lamp were spinning?
It seems the unit has many repair history, according to report from Mr.Jo.
he replaced PMP and formatter in the past, What was the original issue onsite ?
Thanks and Regards,
