How to fix black screen on Dodge Ram?
How Do You Reset the Screen on a 2019 Dodge Ram? Press and hold down the radio’s tuner button and volume button at the same time for 10-15 seconds. Release. The screen should go black and then power on by itself.
I’d contact your dealership as I think that would be under warranty still. Dumb question, but that’s where I always trouble shoot first, did you accidentally hit the button that turns the display off?
I tried depressing the tuner and volume bottons for 15 seconds but that didn’t work. I also checked to make sure I didn’t turn the display off. The warranty is not very good on the Ram. It’s only got the basic warranty for 3 year/36,000 miles and 5 year/100,000 mile powertrain so this wouldn’t be covered.
I did some on-line searching and one forum said to disconnect the battery so I think I might try that. I don’t know if I’ll need a radio anti-theft code if I disconnect the battery. I don’t know what the number is if there even is such a code number for this truck. I bought the truck used and the owner’s manual and all the other documentation was missing.
Thanks for the link. I’ll check to see if I can figure out if there’s an update available.
Thanks for everyone’s help.
