How old is the unit? Have you cleaned out the insides so the air can flow through it?

Why would my projector refuse to start with a seemingly intact light bulb?

If you only have 300 hours on it it should still be under warranty. Before doing something to void that I would check with Optoma techs.

I have a View Sonic pjd5112 projector that will not turn on. When I press the power switch, I hear a small click. I hear another one after about thirty seconds or so. The fan does not come on.

I too have the same problem. I am going to email 800 schools on my database and tell them to steer clear of this brand to avoid the same issues.

Projector will not turn on. The power light is solid Blue and clicks every minute or so like it is trying to start but nothing happens. It has happened to two projectors. I am baffled as to the solution....

I too have to same problem, did you find a solution? I swapped out the existing fans with different ones to try to solve the problem to no avail. I inspected the bulb for signs of malfunction and could not find any. Any updates would be wonderful!

The red lights on the control pannel indicate that there is a problem with ventilation (the fan or whatever is called). Can I fix it? The PJD5112 lamp turns on just for seconds and then of and red signal...

The projector switches off itself due to following problems. Make sure that lamp is not used for more than its life expectancy as mentioned by the manufacturer.The projector gets over heated due to two problems. 1) The dust filters are clogged. Clean the filters. 2) The lamp life is almost over or used lamp is in use. Normally each lamp is used about 2000 to 3000 hours depending upon the manufacturer. In such case replace with new lamp. There are many fans to control the temperature inside. Some are blower fans. Some are exhaust fans. You will have to open the projector & check which one of them is not functioning. Replace the one which is not functioning. It is also likely that there may be some failure of components.
