*Solved*Tee’d off coming to me, where to look for non-boot issue

I have a nonworking Teed off coming to me tonight and hoping I can get a little direction before it gets here on where to go? When it’s powered on it just makes a long beep and nothing except GI lights on. The PO sent me the following pics of a bent-legged chip and pin connector, would these cause that issue and is that connector even saveable at this point? Any advice I can get would be appreciated!!

Got it home, put in a new battery and what it does is light up, I get playfield lights and a solid beep followed by a few seconds and 4 loud fast beeps and then nothing. Dmd is blank, that’s as far is it goes. All 3 board’s leds are flashing. Is that normal? I noticed that the 3 prong plug is missing the 3rd prong but has the top two, could that affect anything?

The battery looks too small for the holder but it’s a 2032?

UPDATE:

If I give it credits it will start a game. Sound came on, followed by 4 beeps, followed by sound, 4 more beeps and then no sound, zero video but all holes kick out, gopher wheel spins, left flipper works, right upper works and lower barely moves. Lights will go dark periodically and it will kick a couple coils and then lights come back on. It’s possessed? All fuses seem fine? I’m stumped

Thanks for the help guys! We are getting much closer. We had no 110v to the display, fuse holder was bad. Installed a new one and we have dmd working now! Unfortunately when it boots up it says “Street Fighter II”.... so we looked and yup, there’s a SF2 display rom in there. I’m guessing it’s an entire display board from an SF2? My question is can I just swap the rom and it will be fine or do I also need to swap UG-8 that goes with it?

Should it act super weird with the SF2 rom in there? I get the sounds and such but the display has zero video at all, just the score and such. I’m sure because it’s attempting to decipher SF2 code?

She’s all fixed up! New rom burned and it’s 100% now. Thank you guys and please refer to my new bad cars thread on my next pinball problem if you can help . Just got it today
