All of the lamps are 180 watts, it's the voltage that changes with the size of TV. I asked this question a while back on using a 45 volt (used on a 92" model) on a smaller screen size and the answer by another poster was that it would work, it would just be a brighter screen.

With all the TV troubles and blown ballasts people are having with aftermarket and wrongly spec'd lamps, I wouldn't risk it. Stick with the correct lamp supplied by the manufacturer.

There is no orange LED. If it's flashing yellow, check that your lamp door is completely closed.

If there is no orange then it must be red but it looks orange to me and my wife. I have never replaced the lamp (bought it in Dec 2011) so maybe it just needs a new lamp?
