 ## My gamepad doesn't work
 
 If your gamepad doesn't work in the menu, you need to make sure you have [defined your inputs for that gamepad](../setup/controller.md){target=_blank}. If your gamepad doesn't work in the core, but it does work in the menu, then you need to define the gamepad in that core in the secondary OSD menu. If neither of these work, make sure you your DIP switches are correct as shown above.

 If you have a fancy gamer keyboard with lots of macros and RGB lights, it's possible that the stock power supply is not providing enough power. You may want to consider purchasing an upgraded power supply with more amps as a way to fix this, like the [Mean Well GST18A05-P1J](https://www.amazon.com/MEAN-WELL-GST18A05-P1J-Desktop-Adaptor/dp/B01LZ0LJXQ){target=_blank} or take a look at this [DigiKey search result](https://www.digikey.com/short/33rwd9pm) to get a better idea of what is required. Generally speaking you need a 5v power supply with more than the stock 2amps, with a 2.1mm x 5.5mm x 11.0mm barrel plug that has positive center polarization. Mean Well and Triad are often recommended brands, but they are not the only option if you cannot find them at your desired retailer.
 
+## The lights on my MiSTer light up, but I don't get video out of the HDMI port
+
+If your MiSTer looks like it's booting up, but you don't get any video output from the HDMI, there are a couple of things you should try:
+
+1. Do the usual basic troubleshooting by checking that the cable is good and has a good connection to both your MiSTer and the display device.
+2. Try another cable just in case
+3. Pop the SD card out and back into the slot. (if the MiSTer can't read the SD card (or the card is empty) it will fail to boot completely).
+
+Finally, you can verify that the MiSTer has booted by using connecting to it via either SSH or FTP. If you can connect, then it has booted.

 ## Fixing missing certs
 
 If you are unable to use wget, this might be because you are missing security certificate files. The default system comes with no security certificate files so you need to add --no-check-certificate on wget to download anything HTTPS:
