50hm66

Welcome aboard.

Have you tried holding the power button in for 6 seconds?

Give that a try and if unsuccessful provide details of make and model. Hopefully someone here has seen it before.

Cheers,
Bill.

Try leaving it unplugged overnight. Do you hear the fans and the color wheel spinning up?

The code for a blinking yellow light is 'Standby - Quick Restart On'. Just to confirm, there are no other LEDs flashing at all?
