Hello, I have a problem the pupitre Siemens 6AV6643-0DD01-1AX1 THIS IS THE LINK https://www.cofiem.fr/fr/22749-siemens-6av6643-0dd01-1ax1.html?gclid=Cj0KCQjwz4z3BRCgARIsAES_OVdbUuKb6_nnqL0HDRwDOt8dj-gNKnZwPPtLEAPfv4YMyux8mdPi0N0aAqS6EALw_wcB the 24 Volt power is ok but the device screen does not display anything! The screen seems to light in green and the power seems to arrive to the screen device but nothing is displayed so we cannot use it. Where can the problem be? is the screen out of service? |

Please send it for repair to the siemens service center. Do you have final commissioning backups? Please note that the product is phase-out. Link Please ask for final commissioning backups.In case if it is not repaired and the new same HMI is not available in stock. Then we need to download in a successor version after a project migration |

Hello df; As long as you have the screen open, I would suggest you look at the small fluorescent tube that should be located at the back of the screen, on the circuit board. The screen uses LCD TFT technology, which requires a source of light for the screen image to become visible. If the backlight is no longer working, the screen will appear blank, with no graphics or characters visible, even though LEDs or other signals work. The screen uses a CCFL tube as backlight source.. Unfortunately, I cannot locate a part number for this CCFL tube in Siemens site, the screens have been declared obsolete for some time., However, when we were working with MultiPanels, we would source them from nearby vendors, such as this one: https://www.ccflwarehouse.com/ccfllamps.html The screenshot below has been extracted from this manual: https://public.eandm.com/Public_Docs/MP%20277_e.pdf Hope this helps, Daniel Chartier |
