When the projection lamp in your Sanyo Projector is nearing the end of its life, promptly replace it with a new one. After replacing the lamp, remember to reset the lamp replacement counter.
What to do if WARNING (red) and POWER (red) indicators are blinking on my Sanyo Projector?
If the WARNING and POWER indicators are blinking red on your Sanyo Projector, it means the projector has detected an abnormally high internal temperature. You should check the air filters and remove any obstructions near the intake and exhaust fan openings. After doing this, wait for the POWER indicator to stop blinking before attempting to turn the projector back on.
Why is the WARNING indicator light red on my Sanyo PLC-WXU300?
If the WARNING indicator light is red on your Sanyo Projector, it indicates that the projector has detected an abnormality either in the cooling fan operation or in the power supply secondary circuits. You should check the fan operation, power supply lines, and the driving signal status.
What to do if the lamp cover is not mounted correctly on Sanyo PLC-WXU300?
If the lamp cover is not mounted correctly on your Sanyo Projector, check the lamp cover and the lamp cover switch (SW901).
How to troubleshoot all LED indicators not lighting on Sanyo Projector?
To troubleshoot why all LED indicators are not lighting up on your Sanyo Projector, check the primary power supply circuit and parts, including the AC cord, F601 (Fuse), Power board, and SW902 (Thermal sw.). SW902 should be short in normal operation but opens when the surrounding temperature exceeds 100°C.
