Optoma HD70 clicking problems (Video)

I just got a used Optima HD70 that was working great until last night. It shut down correctly.
This morning I turned it on again and the orange LED lights flash and the power light stays green but no fan turns on, no light turns on and all I can hear is a slight clicking sound inside the case.

I have removed / reseated the bulb and while the bulb is old. I did not see a broken bulb. I also dusted out the projector and the problem still persists. Maybe you guys can help!

The ballast is probably bad and can't ignite the lamp. That would be my guess anyway.

After looking at many things, could the color wheel have died? Whenever it used to start up there was a light high pitched sound when the color wheel spun up , but after a couple of seconds it went away.

There was never any of the traditional signs of it failing (colors changing, working for a short time than shutting down), it just worked one day, and shut off the next.

But, listening to failing color wheels, that high pitch sound does sound familiar, it just wasn't constant or very loud like the rest, just a couple seconds.
