I had DE3815TYKHE for a while, trying to fit that into my car. So while I was distracted by failing usb peripherals, I didn't pay attention and connected NUC to 12V with reverse polarity. Yes I should have checked it with voltmeter and I knew it can damage unprotected circuits. But since much cheaper Arduino boards have reverse polarity protection, I though Intel would do that too. I WAS WRONG.
That's a bit frustration for a premium priced DIY item.
So I am attaching a pic. Looks like one resistor is burnt, maybe something else also happened. I didn't check other side of the board yet.
So a few questions to ask that may be helpful:
- Is this item NOT supposed to have polarity protection? That means no warranty on it and asking Intel for paid-repair probably will cost more than new item.
- Can I repair this myself? That means I need to know resistor value that's gone. I can desolder and replace myself. That should assume NO OTHER parts are damaged. Soldering work on these SMDs are very difficult, I can't replace major parts. That case, it will go to trash.
Thanks
