Hello experts! I am currently facing an issue with my Mitsubishi E1071 HMI. When I power on the unit, it goes through the booting process and then displays a black screen after loading the application. I have also tried different settings using the dip switches, but the result remains the same. I have attempted to reset the settings, and although it was successful, the issue persists. I have also conducted a self-test, which showed everything passing except for the battery at first; however, I have since replaced it. Can anyone provide assistance with this issue, or is my HMI beyond repair?
If you have E-Designer, make sure to check if anything appears on the screen when you boot up. If the screen is at normal brightness, it may indicate a faulty unit. However, if it appears dull, it could be a backlight issue. Keep in mind that the E series has been succeeded by the newer IX series. If your unit is not working and you are unable to upload the application to E-designer or do not have the original file, your options are limited. Consider getting a replacement unit, either second-hand, repairing it, or upgrading to the current IX model. Without the project file, upgrading may not be possible.
If a device passes all tests successfully, it indicates that it is not completely faulty. In order to conduct these tests, both the screen and backlight must be fully operational. One potential solution to address any issues could involve a firmware upgrade. The firmware file can be obtained from Beijer Electronics website. However, setting up the firmware may require some effort. For detailed instructions on performing a firmware upgrade, refer to the Service and Maintenance manual available on the Beijer Electronics website. To optimize the backlight settings, load a project with the backlight turned on and set to a moderate level. These adjustments can be made in the 'Setup/System Signals' section of E-Designer. By setting the switches to 1000, access the User Menu and upload a new project to the HMI. Alternatively, connect to the device using a web browser. You will need to know the HMI's IP address, which can be configured in the User Menu. Through the web browser, you can adjust the backlight settings without encountering any issues related to the backlight level. If the issues persist, consider seeking professional assistance. It may be necessary to replace the HMI unit, so explore all available options in the market before making a final decision. Beijer Electronics may not offer all the necessary components or a suitable price point.
When booting up, ensure you have E-Designer connected to see if the screen displays normally. If the screen is bright, the unit may be faulty; if it is dim, the backlight could be the issue. The E series has been replaced by the newer IX series. If the unit is unresponsive and you cannot upload the application or do not have the original file, your options are limited. Consider getting a second-hand replacement unit, repairing it, or upgrading to the current IX model. Without the project file, upgrading may not be possible. Keep in mind that sometimes the application is accessible but the screen turns black after a few minutes. Connect to E-Designer for troubleshooting.
BryanG noted that if a device passes all tests, it cannot be entirely defective. In order to perform tests, the screen and backlight must be operational. To troubleshoot, consider a firmware upgrade by downloading the required file from Beijer Electronics' website. Although the installation process may be challenging, refer to the Service and Maintenance manual for instructions on how to upgrade the firmware. One potential solution is to load a project with the backlight set to a mid-level in the 'Setup/System Signals' section of E-Designer. Access the User Menu by setting the switches to 1000, which should allow you to upload a new project to the HMI. Alternatively, connect to the device using a web browser after configuring the IP address in the User Menu. This method bypasses any backlight intensity issues. If these steps do not resolve the issue, there may be underlying problems. Consider exploring the full range of options in the HMI market before considering a replacement. It is possible that Beijer Electronics may not offer all the necessary solutions at an affordable price. Finally, if all tests have passed, pay attention to the display colors during the self-test process for further insights into the issue.
As per Brian's suggestion, it is important to investigate the power supply as well. I recall a situation where the 24v supply was actually only 20v due to deteriorated smoothing capacitors, resulting in a significant ripple effect that caused the screen to blackout. It is also possible that failing components, such as electrolytic capacitors in the HMI, may be contributing to the issue. Don't forget to thoroughly check these components to ensure smooth operation and prevent any screen issues.
Hey there! I've experienced a similar issue with a different model in the past. Based on your description, it's possible that the problem lies with either the OS or the application. I'd suggest attempting to reload both. If the issue persists, it could be a hardware problem. Regarding hardware, it's possible that the backlight of the display has gone out. Try shining a flashlight on the screen when it goes black to see if you can see any images faintly. If you can, it's a sign that the backlight needs replacing. Hope this helps, and if all doesn't pan out, consider reaching out to a specialized technician. Best of luck!
Hey there! It seems like you've tried a fair bit already. The issue seems complex, but not necessarily irreparable. Just one thing comes to mind: have you tried uploading the original project file into the HMI again? It's a possibility that the project file might be corrupt. If you don't have a backup, you might need to recreate the project. Also, another approach could be checking the screen brightness. Sometimes, if the screen brightness level is set too low, it might appear as if the screen is black. Finally, if these don't work, you may have to consider sending the unit for professional repair, as the screen itself or internal components may be faulty.
It sounds like you've done extensive preliminary troubleshooting yourself which is great! One possible cause might still be an issue with your application file. This issue might arise if the application file is corrupted. It's also possible that there is an internal fault with your HMI. You could try completely reformatting and restoring your HMI or testing a different application file before declaring the HMI beyond repair. Alternatively, if you have the option to send your unit to a service center, they might have more specialized tools to diagnose and fix the problem.
It sounds like you’ve already tried some solid troubleshooting steps! Since the self-test passed after replacing the battery, we can rule out that as a major issue. Have you checked the connections and cables to ensure everything is secure? Sometimes, a loose connection can cause display issues. Additionally, if you have access to the original application files, it might be worth trying to re-upload them, as they could potentially be corrupted. If you’ve done all of that and the screen is still black, it might be time to consult with a Mitsubishi technician, as there could be a deeper hardware problem at play. Good luck!
It sounds like you’ve already tried a lot of great troubleshooting steps! Since the self-test passed and you’ve replaced the battery, it might be worth checking your firmware. If there's a way to update or reinstall it, that could help resolve any software glitches causing the black screen. Also, make sure all connections are secure, as sometimes loose wiring can lead to these issues. If none of that works, consulting the manufacturer or a specialist could be your best bet before deeming it beyond repair. Good luck!
