Something else I just noticed is that my clock is staying on constantly now, and the clock is the only thing that works other than the boost gauge. It’s odd to me that the clock will appear, but the info screens will not.

The boost gauge is mechanical and I assume the clock would normally be showing without the ignition being on. All the other functions need the ignition to be on, which suggests to me that the ignition feed has failed for some reason. I would find out where that feed is meant to come in on the cluster and see if you're getting 12V there.

That is a good point actually, although all of the warning lights still come on when you turn the key.

I did check out erie’s Ebay and found one on there going for around 100...but I haven’t seen any junkyards around here with any Volvo’s.

The caramel color might be electrolytic capacitors that have leaked and failed. These capacitors look like little cylinders. Generally speaking (all applications) they often fail simply due to age.

Your problem may be due to something completely different.
I’m honestly not sure what this stuff is, but am I wrong in thinking that the best idea may be to just find another cluster? Lol

When re working a faulty electronic board from a out sourced manufacturer , I would resolder the components then ‘paint’ over a varnish lacquer ( or just a permanent marker pen in a pinch). I would say on assembly of the vehicle a fault was picked up and repaired in factory or an under warranty remanufactured cluster was installed after sale.

Will one out of an 850 work?

I got off of work today and rushed home to install the new cluster I ordered. I put it in and put everything back together... and it works! So I’m pretty happy about all of that. Thanks for all of your input!
