beep, no power repair

Hello,

I am repairing some PS5 console with common beep - no power issue. I quickly measured common locations for shorts and I think I found one, but I'm not really sure if it's a short or is intended behaviour. It's near Dialog DA9081 power management chip, where an inductor (at least I think it is) is connected from what it looks like to me a common connection of pins 21, 22, 23 and 24 - although I find this very strange, as 21 and 22 are analog inputs, 24 is positive voltage terminal and 23 is analog ground. The other side of this inductor is shorted to ground, but there are clearly some capacitors so I think there should not be a short. Before I remove the chip I would like to hear your opinion.
I removed this what I think was inductor and took a shot with my microscope. Rectangle is where inductor was and I marked the X spot where I'm measuring against ground. I must say that short is only measured if I put positive probe to X and negative to ground. If I reverse it, I don't get a short.

BTw, anyone would know what value is this inductor so I can replace it once I find a defect?
Thanks

So after doing some quick research on your problem, the Dialog DA9081 chip is used to manage the PS5's power, and there is a damaged inductor, without an inductor, it may not be able to properly manage its power effectively leading it not to properly boot. However, its tricky to determine what the inductor's value is to replace it. What i would suggest doing to solve your problem is finding a donor PS5 Board from a place like eBay, and then replacing the resistors to fix the problem.

Thank you for your answer. I beleive, that this inductor that I removed was not damaged prior. I just thought it was a capacitor as I measured short, but later I realized it was an inductor. While desoldering it, I damaged it so I need new one.

Main issue is now short that I'm measuring without this inductor as I mentioned and marked on the image. I'm wondering if this short is normal (created by some semiconductor somewhere else, because I'm only measuring it in one way) or should I assume that chip is faulty?
