Sound like the original color wheel for Optoma HD80 is bad.

If the unit has been moved when hot.

If not, try un-plugging the unit for a few minutes and re-connect.

Hope this helps

My Optoma ES522 keeps blinking all the colors of the rainbow and then going to grey. I have to turn it off four hours to even get it to start up again and then sometimes within minutes it happens again....

It seems that's the color wheel problem. You can fix this by your own. Probably the dust covered the color wheel sensor so it doesn't spin at specific speed.

And the project is now telling my lamp is at the end of it's useful life. How much will it cost to replace that?

You can switch off lamp reminder in OSD menu settings. This reminder is usually set to approx. 1200+ hours. When you exceed this limit, reminder starts to pop up. Actually it doesn't tell anything about PJ's lamp condition. So that doesn't mean that something is wrong with your lamp, maybe it lose some brightens, which is typical phenomena wheen exceeding half of lamps lifetime.

GENUINE new lamp costs around 160-180€, COMPATIBLE COPY should cost around 100€ +

Optoma EP716 turns on but no picture displays


Don't ever just unplug the power cord while it is on. The bulb needs to cool down with the fan still on.
Did you ever connect a source?
