Data projector is not turning on. How can I
open up the top case. the fuse will be on the power supply board right next to where the power cord plugs in. you'll need a continuity tester to test it. if it is blown, replace it with the exact size and type. if it is not blown, replace the power supply.

Lamp/cover button blinking red, how can I solve my Sony projector?
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:
- 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.
- 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.
- 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.
- 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.
- 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.

Sony projector vpl-ex145 light ok, but no lable information
If your Sony projector (model VPL-EX145) has a light that is functioning properly but is not displaying any label information, there could be a few different issues causing the problem. Here are a few things you can try to troubleshoot the issue:
- Check the projector's connections: Make sure the projector is properly connected to the computer or device that is sending the video signal, and that the connections are secure. If the projector is not properly connected or the connections are loose, it can cause the projector to display a blank screen.
- Check the projector's settings: Make sure the projector's settings are properly configured for the type of video signal you are using. If the settings are not correctly configured, it can cause the projector to display a blank screen.
- Check the source device: Make sure the device that is sending the video signal (such as a computer or DVD player) is functioning properly and that it is properly configured. If the device is not functioning properly or is not properly configured, it can cause the projector to display a blank screen.
- Check for any other visible issues: Inspect the projector and its components for any visible issues that may be causing the problem. This can include debris or foreign objects that may have gotten stuck in the projector, or damage to the projector or its components.
If you have tried these troubleshooting steps and the problem persists, it may be necessary to have the projector serviced by a professional. A technician will be able to diagnose the problem and determine the necessary repairs.

Touch screen not working for sony snaplab up-CR20l
Hi,
Please turn off your device, clean the screen and power on the device before using it again. Otherwise, you might verify that you're using the device in an environment of moderate temperature. If still not working, then you might need to run a factory reset on the device.
Thank you.
