Hi everyone,   I recently acquired a Bang & Olufsen Beocenter 1 in beautiful condition, but I have a few issues I'd love to get help with:   **DVD Player:** - The tray opens and closes normally - However, discs never load — the player doesn't recognize any DVD - I suspect the laser lens might be dirty or worn out, but the lens is not accessible without disassembling the unit   **Motorized Rotation:** - The Beo4 remote triggers a small noise from the motor when I try to rotate the screen, but the screen doesn't move - I can rotate the screen manually without issue — it's smooth with a nice resistance, feels intentional - The screen seems to rotate 360° freely with no hard stops — not sure if this is normal or if the stops are broken - I'm also unsure what the original/default angle position should be - I suspect the drive belt for the rotation motor may be broken or melted   **Questions:** - Is the 360° free rotation normal, or should there be mechanical stops? - How do I identify the original screen angle? - Which drive belt reference should I look for to fix the rotation? - Is the DVD laser accessible without full disassembly? Any tips?   Thanks in advance for your help, this unit is gorgeous and I'd love to restore it fully! 🙏
