Hi all, I bought a c64 mini yesterday and I think it’s broken already.
So I noticed first of all, an emulator messed up, loads of random errant pixels on the screen, joystick did nothing.
Rebooted- screen gets very flickery, picture lost roughly 80% of the time. Try a different hdmi lead, nothing. Switch it back, nothing, try a different hdmi port, nothing.
Try to reboot again, no power. Try a different power lead, nothing.
Being totally honest I think it’s messed something up inside and that’s caused other problems on the board. Any ideas? Thanks

Try a higher amp rated USB power supply. The ones the mini or maxi came with sometimes are bad and I think if I remember right they actually were shipping ones with too small of amps needed in some cases?
If you didn't pay much for the mini and it is bad might be better to just keep it and buy another rather than send it back. You could take out the board and throw a raspberry pi into it for a nice little retro gaming pi case.

What’s the best power supply spec? Think one of them was 5.2v 1.3a?
There was just a cable supplied with it.
The Pi case idea is interesting, I have a 3b in a nes style case that I need to finish the build of

Can't remember what they recommend in amps for the C64 mini, Maxi, or A500 mini but I do know even what they recommend isn't necessarily what you need when you've got enough stuff plugged in such as keyboards, joysticks with internal batteries that want to charge, etc. Often these power demands can cause issues like thinking the plugged in devices aren't compatible. Just remember that as a general rule a higher amp delivering power supply is usually the best option in most cases because in general a plugged in device only draws the Amps needed. Where things get a bit more risky is trying to supply a device more volts than it's rated for. That's usually when things short out. Think of it this way. You can have a battery the size of a can of pop or one the size of a house, and as long as the voltage is within specs the amp delivering ability of hours, days, or months won't mean the device plugged into it will fry being forced to suck down those amps. It's only going to feed off the amps it needs. Voltage is different though.
I'd also add this one important warning. There are certain situations where amp requirements can force feed themselves through a less amp hungry device and fry everything. Just being real here. Like trying to jump start your car with a smart phone that has other stuff demanding that action plugged into it. NOT a good idea.
