I had to replace the LCD screen. It is also possible that there is damage to the driver board under the LCD housing. Large selection of cables on Ebay.

In the BV10-32 I once repaired, I had a similar defect, a damaged LCD screen. You can disassemble the screen and check the ribbons connecting the T-Con – LCD screen.

This is the original capacitor from Beosystem 4.

BeoSystem 4 boards already use a 3300uF capacitor.

I don’t have any photos. I cleaned the PCB under the capacitor to bare copper, soldered the paths with thin wires and covered them with PVB varnish.

Hello, in my case the electrolyte from the damaged supercapacitor damaged the PCB paths that ran under it. I could barely solder them.
One of them is the signal from the IR module to the FEP IC300 processor.
