If the LAMP REPLACE indicator on your Sanyo Projector lights up yellow, you should replace the projection lamp with a new one as soon as possible. After replacing the lamp, make sure to reset the lamp replacement counter.
Why my Sanyo Projector cannot be turned on due to abnormally high temperature?
Your Sanyo Projector cannot be turned on because the temperature inside is abnormally high. When the projector has cooled down and the temperature returns to normal, the POWER indicator will emit a red light, and you will be able to turn the projector on. Also, check and clean the air filter to prevent this from happening again.
What to do if my Sanyo PLC-XU87 Projector cannot be turned on until cooling is completed?
Your Sanyo Projector is either preparing for stand-by or the projection lamp is cooling down. Wait for the process to complete before attempting to turn it on.
What to do if my Sanyo PLC-XU87 detects an abnormal condition and cannot be turned on?
Check the power supply circuit and the fan control circuit of your Sanyo Projector.
