Hope someone has an answer for me... I'm clueless.
My HC1500, which I have not used for 4 years, just went down into my basement rec room. I started it up and it looked fine. It started two or three times while I adjusted it.
Then it shut down. No pop, just power off. Now I try to start it, and I see the lamp come on. But then it makes two short startup whines (two green lights), then shuts off again (one red power light).
The manual states to look for the blocked air intake. Nothing is blocking my air intake and I tried blowing it out with a blow dryer.
Since I see light from the lamp, I am not sure buying a lamp can help. Is there anything I can do?
I don't think it's really worth paying to repair since superior projectors are now very reasonably priced.
Thanks for any clues anyone might have...

Fair enough, I kind of see why you mention that now that I'm comparing my current unit to the HD26 which would just barely fit my room and would probably light it up like the sun.
currently I'm running a 144" throw. There are a few inches for expansion if vents are in the right place, etc. Screen is 102", and of that I'm using right about 100".
According to the calculator, which I used as a double-check on the measurements, my current unit's throw ratio is 1.67-2.02 with a zoom of 1.2.

I have an hc1500 that is about 4 years old. Recently it has been having some issues...sometimes the the picture flickers, gets brighter and darker. It will do it a few times, then be ok for a little while....now in the last few days, it will randomly shut off. Yesterday i got a message on the screen about the lamp nearing the end of life and i should prepare a new one.
I run this unit in low brightness mode all the time, and the lamp hours were at 2250...this is well below the 3000 advertised, and i think a bit early to start warning me about replacing the lamp. I found a thread online somewhere where they suggested resetting the lamp counter, which i did. However the flickering and random shutdowns are still occuring.
I have the projector plugged into a ups battery backup / surge protector, which should eliminate any power issues. I have multiple video sources connected to the unit, some via hdmi (ps3, directv, pc running xbmc) as well as an xbox 360 and wii connected via component video. The problems occur no matter which source is being used. I am pretty much assuming that the lamp needs to be replaced, but i hate to spend the money if there something else i can try first. It is still very bright, and sometimes i can watch a full movie without it shutting down...other times it may shut down after 15 minutes.
Should i just replace the lamp? I have found a lot of replacements for around $120 on amazon, are they any good? Or do i have to try to find an official Mitsubishi lamp, which i am having a hard time locating...and i am sure will be at least double that much?
USD120, it is reallly cheap one, certainly, it is no doubt, it is real replacement lamp, and bare without housing.
compared with original lamp, replacement lamp is cheap, if you are lack of fund budget, it shoul be selectable.
but its brightness is weaker than origianl lamp, shorter service time. totally review, original lamp is more economical.
original lamp with housing is not much more higher than replacement one.
i have this source, cost you about USD238 with shipping. 6 month warranty, once happen brightness go down, lamp burnt out or smash in 6months, free exchange new one.
if you are interested in it, please show your email here, and i will contact you later.

I noticed that you had the projector for 4 years without replacing the lamp. That is a long time between lamp replacements. Although the lamp is rated at 3000 hours, it is affected by the number of "starts". In four years you have probably accumulated some dust in the filters and probably on the lamp. This increases the temperature inside the projector and it will affect lamp performance. We reccomend that you get a new lamp, and keep this one as a spare. Make you clean your filters so you get maximum ventilation and maximum lamp life.
