I think I fried my arpicade PCB:(

[gyromite69]

I was trying to connect an LED light for my marquee through usb and I noticed that the lightning bolt in the corner popped up on the top right corner. I then proceeded to up the voltage on the power supply just a hair to see if it’ll go away and the screen just went black. i was like Damn! I think I just f***ed it up! I tried to bring the voltage to normal again and, nothing. I then took the pi off the arpicade and connected it through the power port like normal, and it works fine. When I connect the pi through the arpicade, nothing happens. I think my arpicade pcb is done. Is there an easy way to fix this? Or do I have to pay another $150+ dollars to replace this board? If that's the case then, I'll just throw back my Pandora's box. I don’t want to do that but, the wife would kill me if I ordered another one.

You've probably just blown the fuse on it but if there is any further damage don't worry it's all repairable. It's possible if the fuse blew the video section of the PCB or the DAC could also be damaged but for now I'd check the fuse. Use a multi meter to check the continuity across the fuse, located under the Pi roughly where the SD card goes into the Pi. Assuming you need to replace it use a 2A or 2.5A fuse, not the 1A marked on the PCB.

If there's further damage it can still be fixed but you may just be OK with a fuse. Report back how you go.

I’m googling 2A fuses and they look different. They look like the glass fuses with the metal ends. Can I use those? I can’t find one identical to the one on the board.

This is the original 2A fuse (Australian link but seeing it may help you find it).

You could use a glass fuse but you would need to replace the one that's there with fuse clips to hold the new fuse. I've seen one person do that before. Either way the result should be about the same.

I bought these from amazon. You think these would work?

Should be perfect.

Thank you!!! It worked! To see the pi light turn on as soon as I connected the power was a huge sigh of relief! I can’t thank you enough for replying and helping me get this problem fixed! I greatly appreciate it man.
