Black screen of Death. What I did.

[TAK]

In case you did not see my info, Ram 1500 2021 LTD. Loaded. The other night I left the trailer 7 way plugged in over night (I can not remember if I ever did this b4). Battery dead next morning . Used one of those small super charger and got it started. The big screen was dark. My fix. Disconnected the battery waited 10 minutes and re connected. Screen back on , however the A/C acting funny and missing some of the major apps. Etc. suspension and deploy or lock step. Fix… push and held simultaneously volume and tune button for 10/15 seconds and every thing back to normal .
Lot a posts on this b4 however sometimes an update is good to see.
