I'm in the same boat. Bought mine about a year ago when they were on sale. It had been great until I turned it on yesterday, picture was very dim. I checked the settings, all looked fine. I too was always running in Eco mode, thought that was supposed to extend the lamp life. Mine only has 450 hours on it.
I would be very, very unhappy had I paid the $3000 MSRP and then had to replace a $500 lamp after only 450 hours, in Eco mode! I will be very disappointed if Planar won't help in this situation. These are obviously defective lamps. I know they only have a 90 day warranty on the lamp, but they should at least cut us a break on the price of a replacement if we got a defective lamp.
Based on the other posts, sounds like I can expect the lamp to go out completely any day now. Can anyone who found a better deal than what planaronline.com sells them for PM me?
If anyone gets Planar to work with them in this situation, let me know.
