Projector turns off after about 30 minutes. What's wrong?
Can someone give me any ideas as to what might be wrong? I can use the projector for about 30 minutes, then the lamp cuts off. The power light is red and the status light flashes green. Do I need a new lamp or what?

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.

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.
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 [email protected] if you need a manual.
Re:"a clicking sound that continues for 20-30 seconds than stops as the
projector "gives up" trying to turn on"
The clicking sound and the projector not responding is not indication of a particulare issue or fault, but just the generic protect mode that kicks in whenever a fault is detected. The condition is called protect mode or protection. The clickin noise is a safety switch that keeps turning off the unit until the projector shuts down completely.
When the problem is the lamp the unit does not go into protect mode, but usually there is a well defined diagnostic condition (eg. a lamp light on). I do not think that the problem is the lamp. Most common failure is the PSU (power supply), with in second place convergence issue. Other faults, like the lamp power board or main digital board failure are still possible.
As first trubleshooting, try leaving the projector off and disconnected for one hour, that will probably not help, but is a necessary step to ensure that there is a fault.
If that doesn't work, then the choice is between calling manufacturer and taking the projector to a local technician.
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.
