Question about a weird batch of 2021 Samsung monitors

Had a crazy week last month where four of the same model came in, all with the exact same power board failure. They were all from a local office that bought them in bulk. The fuse and a specific capacitor near the main transformer were blown on every single one. I spent maybe two hours on the first one, then the other three took about 20 minutes each once I knew the drill. It was one of those weird, lucky runs where the problem is identical. Has anyone else seen a specific bad component run on those 27-inch Samsung business monitors from around 2021? I'm ordering a bunch of those caps now just in case.

That's a classic bad capacitor batch. Those office bulk orders all come from the same manufacturing lot. You see one fail, you're gonna see a dozen more. Good call ordering extra parts. It's not luck, it's just how mass production fails sometimes.

Actually the fuse blowing is usually a symptom, not the same root cause. The bad cap creates a short that pulls too much current and takes out the fuse. So they're linked failures but the cap batch is the real problem. It's smart to replace both parts when you see this, because just swapping the fuse will likely blow it again.

I always figured those bulk office buys would have random failures spread out. Seeing four with the exact same blown cap and fuse in one week changed my mind. It really points to a bad component batch from the factory. I'd stock up on those parts too.
