BeoLink 7000
A new stainless steel top plate for the BeoLink 7000
The top plate on the BeoLink 7000 is almost always scratched or dented. I had a replacement made in mirror-polished stainless steel and fitted it with a 3D-printed bracket and alignment jig.
Re-gluing the glass front on the BeoLink 7000
Now and then the adhesive between the glass front and its plastic frame starts to let go on a BeoLink 7000. As long as it hasn't come off completely, a syringe of thin superglue fixes it.
Replacing the piezo element in the BeoLink 7000
Tapping the top plate wakes the BeoLink 7000, thanks to a small piezo element underneath. When that stops working, the piezo is usually the cause, and it can be replaced.
Cleaning and lubricating the BeoLink 7000
Even though the manual states that the need for lubrication is negligible, it is always best practice to clean and lubricate the mechanical components to reduce wear and tear. Lubrication allows the parts to remain in an optimal operational state for an extended period. Since I encountered issues with a Beolink 7000 where the panel remained stationary despite the motor (9017) running, I decided to investigate it. This post mainly focuses on the mentioned problems but will also cover which passive components to replace on PCB01.
BeoLink 7000: when a new backlight foil doesn't fix it
A BeoLink 7000 still had no backlight after I fitted a new EL foil. The cause turned out to be a failed transistor in the backlight oscillator.
Testing the BeoLink 7000
After replacing the backlight and restoring the BeoLink 7000 it is important to verify that the remote works as expected. Funny enough B&O has made this possible in a rather funny but easy way. By adding a 10Hz signal with a maximum amplitude of 5V...
Replacing the CMOS battery on the BeoLink 7000
An essential part of the restoration process of the BeoLink 7000 is to replace the CMOS battery. The CMOS battery ensures that the processor preserves its configuration, should the main battery run out of power.
Replacing the backlight on a BeoLink 7000
A common issue on the BeoLink 7000 is weak or absent backlight as seen in the picture below.The backlight in the BeoLink display comes from a white Electroluminescent Backlight Foil (EL Foil) that is placed behind a blue-transparent LCD. It has a typical...
