I need help cause my controller won’t charge when I plug it in. I just starts blinking red and green. Any suggestions?

It means that you need to update the controller I’m pretty sure.

Ok thank you I will try that

Actually, you should look at the guide that was referenced by @SCFarrell and see what the lights are telling you. There are two lights and it’s not clear which ones are green/red or flashing.

I checked the light guide mentioned but couldn’t find what blinking red and green means

I got my info from some VEX thing I read somewhere, but I don’t remember what the document was. I just put it out there because I’ve had luck with it when experiencing this problem. I also didn’t see his problem in the link the @SCFarrell mentioned.

Try this guide. https://s3.amazonaws.com/support-downloads.pltw.org/2016-17/Launch/Troubleshooting/Stand-alone/VEX_IQ_Flowchart_gh+(1).pdf

It has some better diagnostics.

Is this a fresh out of the box controller or something you’ve had for a season?

I’ve had it since the beginning of summer

Did you go through the guides, update the firmware, and try a different cable / charger? If you could explain what you have and haven’t done, and what has and hasn’t happened, that’d be great and could help us help you.
