Regluing the glass front on the BeoLink 7000
This one doesn't come up often, but now and then the adhesive that holds the plastic frame to the glass front of a BeoLink 7000 starts to let go.
As long as the frame hasn't come off completely, I repair it in place. The service manual warns that the back of the glass must never be touched or cleaned with any liquid, so taking it apart is best avoided. I use a very thin, low viscosity superglue and apply it with a syringe and a fine needle, which puts the glue exactly where the bond has failed and lets it wick into the gap on its own.
Once it has cured, the frame sits tight against the glass again.

BeoLink 7000 overview
Backlight
A weak or dead backlight is the most common fault on the BeoLink 7000. The EL foil behind the display wears out, and I replace it with a new one.
Replacing the batteries in the BeoLink 7000
The BeoLink 7000 has two batteries, the main battery and a lithium coin cell that keeps its settings. Both are long past their life, so I replace both.
Cleaning and lubricating the BeoLink 7000
The display lift in the BeoLink 7000 runs on a small belt, gears and a guide rail. I clean and relubricate the mechanism, fit a new belt and replace the capacitors and fuse on PCB01.
Testing the BeoLink 7000
The BeoLink 7000 has a built in test program. I use it at the end of a restoration to check the keys, the display and the memory.
Stainless steel top plate
The top plate on the BeoLink 7000 is almost always scratched or dented. I replace it with a new plate in mirror polished stainless steel.
Piezo element
Tapping the top plate wakes the BeoLink 7000, thanks to a small piezo element underneath. When that stops working, the piezo has usually failed with age, and I replace it.
When a new backlight foil doesn't fix a BeoLink 7000
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.
