Hi, I'm not sure if it's the same problem I had..
I had it on picture mute, for maybe 15 mins, which may not have been a good idea. While it was muted, it made a sparking sound, and then a very loud grinding noise. When turned off, the lound noise stops, and the fan continues as usual for about a minute. As soon as it's turned back on, the grinding noise is back. But the logo seemed to display ok.
I took it in for repairs, and they said they needed to replace the color wheel to fix the problem.

There is no fuse. I took my EP 716 apart to find out why it died. I found a resistor had blown on the power board made by the Tiwan co. Quazarpower.

Most projectors have air filters. Yours may need to be removed and cleaned. No air flow = overheat.

It's a setting in the menu. A few minutes poking around will fix it.
