    Yes
    AI: Have you tried accessing the service menu or performing a factory reset to correct the display orientation?

    you bought a mainboard 17MB97 for a different panel: for VES395UNDC-2D-N01
    your model should mount the panel VES400UNDS-2D-N11, is this correct?

    1. You need the panel profile for the one in the TV.
    2. Save the panel profile from the TV and post here to return the image.

    >>21369234 maybe, I don't know in what configuration the plate was before, but the seller (serviceman) said that it fits perfectly, which is partially true, but the image is already rotated 180 degrees, i.e. upside down

    Added after 1 [minutes]:

    >>21369336 ok...how to do that

    1. Format a stick with FAT32
    2. Create a folder called pq on the stick
    3. Unzip and put the 2 files in the folder
    4. Turn on the TV, USB stick and type MENU 4725
    5. Go to USB Operations and type OK on the remote control
    6. Wait 10 seconds and exit the menu (return, back)
    7. Turn off the TV from the remote control
    8. Wait until the stby LED on the TV stops flashing
    9. Unplug the TV and wait until the stby light goes out.
    10. Take out the stick and turn on the TV.
    If the image is not correct, repeat the operation

Topic summary

A Telefunken 40-inch smart TV model T40FX275DLBPOSX experienced an upside-down picture after replacing its faulty Vestel 17MB97 mainboard, which initially caused a black screen after one minute of operation. The replacement mainboard was identified as configured for a different panel (VES395UNDC-2D-N01) than the TV's original panel (VES400UNDS-2D-N11), causing the 180-degree rotated image. To correct the display orientation, it is necessary to load the correct panel profile onto the mainboard. The procedure involves formatting a USB stick with FAT32, creating a folder named "pq," placing the appropriate files inside, and accessing the service menu via the code MENU 4725. From there, the user performs USB operations to update the panel profile, followed by a power cycle sequence to apply changes. Repeating the process may be required if the image remains incorrect.
