My vt540 bulb is at 60% of its life... and from what I can tell may be in need of replacement (the display is very dim... just no longer as vibrant as it used to be). I called NEC, and they have indicated I am basically SOL... they only warranty the bulb for 6 months or its lifetime, whatever comes first.
Two questions (I searched for answers here... really I did!):
1. should I push NEC to give me a "deal" on a bulb.
2. where is the best deal on a replacement bulb.
