I replaced the bulb in my Sanyo XU50 projector and cleaned the filters. Now when I switch it on using the mains power, the power light goes red, when I press the power button the light goes to green and the fan starts up, then the amber lamp replacement light comes on and the power light then flashes red. If anyone knows how to fix this it would be gratefully appreciated.

The cooling channel is likely clogged by lint and dust. We usually suggest annual cleaning and maintenance to avoid these kinds of issues. It is also possible that the fans have failed.

what about the Projector Condition leds: POWER, WARNING and LAMP REPLACE? How are they lit? For good measure you should also clean the air filter (the projector might not be getting enough air to cool the lamp)
Just had the same problem. Based on other suggestions on here I tried resetting the overheat switch, and IT WORKED!
So, you have to pull the 6 screws (one of them is shorter than the rest, remember where it goes) that hold the top on the projector. 3 are on the back, 3 on the bottom - look for the arrows next to the screws.
Put the projector on it's feet, and pull off the top. The button wires will still be connected, so just hold onto the top and find the black circle/shaft above where the lamp is. The shaft has white paint on the top/tip of it. Push it down with a light amount of force. You should hear/feel it click.
Put top back on, put screws in, and you should be good to go.
Don't forget to reset the lamp replacement counter in the menus.
Turn projector on and before doing anything else, press and hold the UP arrow on the machine for 30-40 seconds WHILE watching the display screen on the wall - the remaining hours will display only momentarily - if you look away you could miss it. Cheers
