I wanted to jump in here.
I bought the WD-73740 back in Feb of this year 2012. The very bad weather we had just last week (4/14/12) caused the tv lamp to blow. The tv was actually off. When we came home, the tv was "on" but with only audio, and no picture. We had a lot of lightening, A LOT. So I suspect lightening spikes caused the tv to turn on (some how), then also destroyed the lamp. Oh... and BTW... the tv WAS plugged into a 20 minute battery backup with surge protector. So if people feel they are save by doing that, think again. Not so true! Battery backup will not necessarily save your tv, or the lamp from blowing in heavy lightening and power spikes.
So my dilemma is.... just how can one protect these tv's in bad weather or during power spikes? The only sure way would be to unplug the tv from the power source. But that is hard to do when storms pop up, or you are away, or in the middle of the night.
I tried the suggestion on the mits web, to pull out the lamp then slide it back in. Also tried the suggested reset procedure. That did not work either.
So on the following monday I called Mits support and they rushed out a warranty replacement lamp. Got it wednesday. Replaced the dead lamp, and the tv fired up right away, picture and all.
But again I ask.... Just how can owners of DLP tv's protect the tv from power surges/spikes/lightening/etc ?????
I don't think it is possible to reliably protect these sets from power issues or terror from bad storms. I guess as long as you are under warranty, they will rush out a new lamp. After that, the only option is to always have on spare lamp nearby ready to go. And if you use up that spare lamp, re order another spare ASAP right away so as to keep a spare on hand.
