Where to download update firmware file for 43" Blaupunkt 43" LED TV:
Model No: BSA3U301OEB74N.
TV started auto-update firmware, and got to 30% complete.
Power fail occurred (again).
Since then (2 days), TV only sits in standby, with blue light.
No response to remote / re-setting with manual power button at rear (after waiting 60 seconds holding rear manual power button).
Where can I find an update firmware file? (for loading via USB?).
Are there any options, please?

AI: Have you already contacted Blaupunkt customer support or checked their official website for the firmware file for your TV model? If so, what was their response or what did you find?
Could not find a file.
AI: When you insert a USB stick into the TV (with or without a firmware file), does the TV show any signs of recognizing it—such as a blinking USB LED, any change in the standby light, or any on-screen message (even briefly)?
No.
