Sony projector 3LCD lamp/cover blink red

The blinking red lamp/cover button on your Sony projector typically indicates an issue with the lamp or the projector's internal temperature. Here are a few steps you can take to try to resolve the issue:

1. Check the lamp cover: Make sure that the lamp cover is properly closed and secured. If the cover is not properly closed, the projector may not turn on or may turn off after a short time.
2. Check the lamp: If the lamp cover is properly closed, the next step is to check the lamp itself. Remove the lamp and check it for any visible signs of damage, such as cracks or discoloration. If the lamp appears to be in good condition, try reseating it to ensure it is properly installed. If you have access to a replacement lamp, try installing it to see if the problem is resolved.
3. Check the projector's air vents: Ensure that the projector's air vents are not blocked or obstructed, as this can cause the projector to overheat and shut down. Make sure that the projector is placed in a well-ventilated area.
4. Reset the projector: Try resetting the projector by turning it off and unplugging it from the power source for several minutes. Then, plug it back in and try turning it on again.
5. Consult the user manual: If none of the above steps solve the issue, consult the user manual for your Sony projector for further troubleshooting steps or contact Sony's customer support for further assistance.

If the issue persists, it may indicate a more serious internal problem with the projector that may require professional repair.

Check lamp door and lamp are installed/seated fully.

How many times is the red light flashing at one time? The flashing is an error code, the number of flashes indicated the problem. It could be the bulb, the fan, a power issue, or even your altitude.

3 blinks is usually lamp door not closed properly (can mean door is warped from the heat also).

Lamp cover is not properly seat-in. Go back to this part, re-insert and ensure that the safety switch will engage to the cover.

I have that manual. There are three lights to the left of the power button. One is labled LAMP. The manual states "The projection lamp, which illuminates the picture, has a limited life. If the screen becomes dark, the color looks unusual, or the LAMP indicator on the front of the LCD projector TV flashes, it is time to replace the lamp with a new one (not supplied). Use a Sony XL-2200 replacement lamp (not supplied) for replacement. Use of any other lamp may damage the LCD projection TV." I also found in a different page " LAMP LED lights up in red when the lamp for the light source has burnt out." I guess burnt out would be extream. I found one other if you had opened the light bulb cover and didn't close it properly. " If the lamp cover is not reattached securely, the self-diagnostic function may be triggered and the POWER/STANDBY indicator flashes three times."

4 blinks is fan error. Just clean the fans near lamp compartment by a vacuum cleaner and check the fan connectors if they are attached securely.
