Technical Issue, My monitor nowdays sometimes shuts off especially when i am gaming

The auto off is designed to help save battery life. The charger cable prevents it from shutting off, at the cost of a REALLY annoying buzzing sound. Sometimes your party members can hear it, sometimes not, and the volume seems to be random. Also, I've noticed
that if I am in a private chat with one person, my controller will not shut off...I am not sure why. It stays on for hours and hours in a private chat, but in parties it shuts off after about 10 min of inactivity.

Sometimes I used it when my monitor goes off signal, so I can change the settings without a screen.

I had similar problem. When I enter a game disc it says the disc is no good try another disc. Hard reset by pressing the on button until it shuts off and then turn it back again helped. I am still monitoring if this will return. It seems that my drive is
making more noise then usual so maybe it is related.

do you have this issue with games you last played and then shut off your console? as i sometimes have this issue when the game says to resume instead of launch, i just press the menu button on my controller to close the game, wait a few seconds then launch
it again and works fine for me then.

Give that a go

I have a similar problem. Sometimes when I turn my console on, it will completely shut off after a few seconds and I have to turn it on again. No issues with signing in though. I have my Xbox set to Instant-On.
