Hi all this is further update on the auto swithoff intermittently 9400
Epson person he removed and refixed the same bulb about 1.5 months back .it worked fine for a month with out any hiccups.
Again it started with same problem,this exactly around 19 min it was shutting off .i complained again .they came they checked and replaced old bulb run for 970 hrs with the new bulb and new filter .
Warranty term is 2 yrs for projector & 1 yr or 1000 hrs for the bulb which ever is earlier.though my projector is 1yr 4 months old they were kind enough to replace newbulb . again it worked 1 week and same problem recurred.
This time they brought some software from the company for fault finding.this was home service.
Within 10 secs of usb connection it showed ballast unit error .
Immediately they ordered ballast unit which is expensive i believe.but luckily mine was under warranty and without any fuzz they placed order.
After 4 days it arrived.
This time along with ballast unit they also got new mother board for uploading latest software.
They replaced defective ballast unit .along with this company changed the motherboard to new one as the old motherboard was not compatible with the latest software.
Now my projector has got new motherboard with latest software update,new bulb,filter and ballast unit.70percent of it is replaced.
Epson service men were excellent and they much obliged to my problems.al this went through smoothly.
