Grundig Xentia 40 LXW102 same as Erae Digital Art ELT-4000AP-EN -Manual Needed

[Technomaniac]

I have a Grundig Xentia 40 Model LXW102 which is marked internally as being an Erae ELT-4000AP-EN, made by a Korean company and its existence questioned by Grundig. I have trouble with the display driver board, which has blown its surface mount rail fuse. Temporarily connecting a 3AG fuse results in a display but only of random vertical lines. Does anyone have data? (Or a driver board)
