Any other B&K Reference 50 Owners Out There? Need a favor, please

Hey guys, if any of you have a Reference 50, S1 or S2, I would appreciate some comparison info, but it will probably require you to pull the cover.
In troubleshooting my recently failed Reference 50, I found something odd on one of the cards. One of the legs on one of the chips is not seated. I haven't had the unit long enough to say that it was in flawless working order, so cannot rule this chip condition out. The unit was exhibiting some lock-ups before failing to power on altogether. I was wondering whether this chip placement with the one leg out was due to tampering by a previous owner, or something that B&K does at the factory.
Would greatly appreciate it if someone with a Ref 50 with relatively easy access would be willing to pop the cover and check their card for the same configuration. Shown here in this first photo, I have the card removed, but you should be able to see whether this one particular leg is seated even just viewing the chip from one side of the unit (indicated by arrow) without removing the card.

I've got a copy of the service schematics if that helps? @mantis has one in a box somewhere......

that would be fantastic if you do! I haven't been able to find the schematics anywhere!
where'd you find this stuff? all the links seem to be dead on B&K's site?
User Manuals are still good, but not the service schematics?
but yeah, if either of you can check this out if the schematic doesn't indicate one way or another, that would be great.I disabled signatures. -
I emailed ATI and asked for em lol....
I also have the owners manual heheheh...

oh, okay, I did think to try that, but it hasn't been a day yet

I'm definitely inclined to agree with you guys, and I'd like to try this, but the fact that it powered on and was mostly normally functional for a while has me scratching my head. could be a compound issue, I'm thinking? power circuit causing the failure to power on and perhaps this leg out causing the flakey behavior? I'm trying to get my hands on the system schematic just to make sure it's not out on purpose. I can't think of any reason it would be, but I just want to be sure before I correct it. right now, I'm leaning more toward a failing/failed power circuit as the main culprit, and don't want to jeopardize any of the digital componentry if for some weird reason this was done on purpose. I can see some wear on the IC leg, so at some point it was properly inserted. Just don't know enough about it quite just yet. it's killing me to not just try this now, though! I disabled signatures.

Honestly, at this point, what do you have to lose by trying it fully socketed? Just a thought."Some people find it easier to be conceited rather than correct."

probably nothing, I just wanted to try to confirm with other owners or by finding a schematic that it is supposed to be fully seated before doing so, just in case there's some weirdo reason it's not supposed to be.
granted that it's unlikely, my concern for reseating is for causing damage to electronic parts that I may not be able to obtain anymore, whereas right now, I think the issue may be limited to some weak or bad components in the power circuit that can be replaced somewhat generically. essentially don't want to make a small problem a big one.
I'm supposed to be taking it to the shop tomorrow. I am considering reseating the chip just to rule it out, but it wouldn't make sense though since it was powering up before, and it's not like that thing could just come unplugedI disabled signatures.
