Denon AVR-3806 Repair Question

So the unit pictured below is one of the pieces I found for next to nothing at a church garage sale a few weeks ago. While testing it out today I discovered that some yahoo broke off the part of a male optical cable I guess while removing it from the back of the unit. There's a plastic part of the optical cable stuck in the female port.

I've tried everything possible including tweezers, a pair of Kelly forceps, a darning needle and a pair of needle nose pliers trying to get that damned little piece out. No luck.

So... taking off the top I see that the optical inputs are part of a green board that connects to the rest of the unit via ribbon cables and sits atop what appears to be a motherboard.

Question -

Is the green board for the optical inputs soldered into the motherboard, or should I be able to wiggle it free after having unscrewed the board from the back of the unit?

There's a service manual at https://www.manualslib.com/manual/949310/Denon-Avr-3806.html The relevant pages are 86 and 88. The board I'm dealing with is part 1-2 on page 86, referred to as a "1U-3700-2:DIGITAL IN UNIT" on page 88.

One of the images below barely shows the stuck piece of cable in OPT-2 in the rear of the unit. The other gives a general idea of the innards of the thing.

Thanks for any help -
