@JusteBelmont said in Lightning bolt appears after previously error-free use! Help please!:

Dosbox is a whole other issue! tell me how to make my mouse work on The Summoning, and I will owe you a beverage XD first world problems

Challenge excepted :) I'm pretty good with getting stuff running on dosbox. Open a new help topic with specifics about the issue with that game and I'll see if I can get it working.

@RyanT besides the fact that we dont support 3rd-Party-Images as mitu mentioned: imo your advise is a bit of asking a crystal ball.
If his Pi only shows the bolt with this new "prebuiltimagefromdahood" - and not with others...i guess it contains overclocking parameters by default.
Without knowing the exact configuration it is impossible to recommend a specific PSU. Maybe the Image was meant for a watercooled Raspberry Pi with a 600Watt PSU - who knows?

Yes. I have receiver. That was my problem. When I connected the receiver, I would get the lightning bolt, but now I am using a 10,000maH powerbank with 2.4A output and I have not had an issue so far. Thanks for your help.

@SeraphisCain

What could have caused it to appear momentarily like that, just as I was shutting down?

I wonder if your heater or AC was kicking on at that exact time or maybe a power brownout or if you're using an old surge protector, maybe it time to replace it. Those things don't last forever and can wear out over time from multiple power surges. Also if you're going to replace your surge, you might as well spend a little more and get a Battery Backup which will help with surges and brownouts. I've got this one that I plug my modem/router into and my main Raspberry Pi.

And is it something I should be worried about?

If it only ever happens once, I wouldn't worry about. If it keeps happening, then it could be an issue. Maybe a short in the power cable? Bad surge protector? Dirty power?

@toucthebitum please note we don't support 3rd party images. You should use the official image from this site.

I got everything working flawlessly with a different power supply: 5.2V, 3A. :)

that worked, I'm up and running now. thank you for taking the time to help.
