Galaxy S10 won't turn on after battery change (it's not a bad battery)
Hi! I just did a battery replacement following the guide here, on iFixit, on my wife's Samsung Galaxy S10+ and everything was going on just fine, all the pieces where coming off as they were supposed to. In the end, I swapped the battery, but the new one in place and tested it to see if it would power up. It didn't, but I didn't think much of it, as the battery could be dead. I closed everything up and tried again. No joy. I powered on the phone and it did startup, then it stopped and showed the water damage warning. I used Isopropyl alcohol to loosen the adhesive and I had to use quite a lot. I didn't have a needle, so I had to improvise with the pick and slowly dripping it against the pick into the battery holder. There was some spillage, though, but I did dried it up with a cloth before connecting the battery. Anyway, I thought: well, it's alcohol. It was late, I just wanted to get to bed and, you know... it will dry up during the night and in the morning and it will be ok. I unplugged the phone and just left it there.
Morning came and I went to check on the phone. Now it won't even power on or show the water damage warning. I did a full tear down, checked the connections, checked for corrosion, everything I could possible think of and I can't find a reason why the phone seems dead (other than somehow the alcohol shortened a circuit in the board). I also used a blow dryer on the parts and that for sure got all the alcohol out. I also checked on the humidity sensor on the sim card and it wasn't tripped.
Does anyone know if there's any part that's essential to be connected, like an anti tampering sensor on the case, that prevents the phone from being turned on without a connection?
If someone has any ideas on how to further troubleshoot this, I'm all ears. I'm not an amateur on these types of repairs, so feel free to go as technical as you want. I saw a post by @oldturkey03, on another thread, with a flowchart of the troubleshooting process and I'm very much interested in following it, but I haven't seen the markings of the parts he's referring to, so I'd appreciate if someone has more information on how to find these parts or a more extensive guide.
Thank you so much for taking the time to read this!
PS: I have, of course, tried to power on the phone with the old battery, which was still usable and had around 20% charge, and closed up the phone before plugging it in unsuccessfully
Bu iyi bir soru mu?

@casually8728 okay I see what you are looking at. Hard to measure components output if the components are not marked. Let me fix something for you.

@casually8728 let's see if one of the phone guru's has a trick up his sleeve. @tech_ni knows his way around Samsung and other mobile phones
