My Sanyo PLV-Z4 has had a replacement bulb (twice in case it was a bulb malfunction) but still flashes amber to replace the bulb and closes down immediately. How can I reset the bulb timer if it won't even turn on in the first instance?

Thanks for the post. The following details are a little more helpful in the process:

1 - Remove the three screws with the arrow indicators from the bottom of the unit.
2 - Remove the three screws from the input side of the unit (1 of the screws is shorter so be sure to replace it in the same spot)
3 - Slide the top cover of the unit up, careful because there are a group of wires connected to it
4 - There is a black button with a white top in the bottom right quadrant of the PJ (assuming the unit is facing away from you), it has 2 wires connected to it
5 - Press the button and hear a soft click
6 - The thermostat has now been reset
7 - Replace the cover and screws and enjoy. Thanks for the post.
