Projector turns off after about 30 minutes? What's wrong.
Can anyone give me an idea as to what might be wrong? I can use my projector for about a half hour, then the lamp suddenly turns off. When this happens, the power light is red and the status light flashes green. Do I need a new lamp? or what?

There are several things that can cause this problem, but the first thing I would check is the filter. The projector requires airflow to keep it cool. If airflow is blocked, the projector will overheat and shut down automatically.
I have a similar problem. JVC Project (DLA-RS1) shuts off after about 30 min to 1 hour of use. Everything turns off - bulb, fan, even the little light on the projector near the buttons. After 10-15 min the red light comes back on and you can start the projector.
I have seen this happen when I had installed a knock-off bulb. I believe the bulb runs a little hotter and the projector over heats. Now I am seeing it happen even with a JVC bulb.
I am in the process of taking the cover off the projector to see if anything is blocking the air flow (like a piece of broken bulb, which did break a while back). If a problem doesn't show up there I am going to check the fan to see if it is turning at full speed (maybe replace with a beefier fan?).
Clean the filters. Make sure that the vents are not blocked. fan are working? Make sure the lamp door is secured, Projector manufacturers will make the projector inoperable if the door isn't secured tightly. Reset the lamp timer. email me at firstname.lastname@example.org if you need a manual.
This is how my problem with the power not going on started. I cleaned mine and it was running much better. I decided to give it a good cleaning, but now the power won't turn on. Try at your own risk as this could happen to you as well. Just a note, I have had mine for 4 yrs with the same bulb, just over 6000 hrs. I was lucky until now.
It turns out that i fixed this issue, I opened up my projector and took a look at the board to make sure that there is nothing wrong. It turns out that the projector needed a good cleaning. Just use caned air to clean out the projector make sure that all the vents are clear and not blocked. (note: do not spray the caned air while the bulb is hot, if you do this the bulb can cause the pressurized air to temporary flame up, Please make sure the projector has had at least 30 minutes to cool off) While the board is off press the power button and the projector should power up. Replace the covering, and this projector will work.
some projectors have a shut down timer. if it not being used for a specified amount of time, it'll go into a "sleep" mode to save the lamp. but the projector was designed for continual use. if the lamp get too hot, say after 12 hours, it'll go into thermal shutdown to cool off. turning it off when not in use saves the lamp a few hours or minute, but it's not necessary. just like keeping your car idle while you're in the house is ok, but it wastes gas and is not necessary.
your projector status means the protection circuit is working or the lamp is in an abnormal condition. --wait until status indicator goes out and press power button. ---if the above solution is not working change the lamp.
all these things leads to 1 conclusion:
the device is packed with tons of dust
it has a safty powerdown on heatup
