Red led in my Xbox Super Slim!!!

Thank you so much, I made a request to repair my console, but retaking the topic, I could see that when I turn on the console the led in the power supply goes to from yellow to green and from green to yellow when I turn off the console. Do you still thinking
it damage is in the power supply? or maybe the failure could be on the console exactly the plug?

Most likely it's a power supply failure. I would try a friend's power supply and see what happens. I would then check with
https://myservice.xbox.com/ and start a request as your Xbox may be under warranty! Let us know what happens, good luck!

Thank you so much for your assistance. I am using a Asus VP28UQG 28" LED 4K UltraHD monitor. Before this one I was using a Gigabyte G24F 23.8" Super Slim 1080p. My current 4k monitor does not HDR.

EDIT: to consolidate this into one thread i will add this here. the power brick has a status LED when it is in use, and when your console is on, it should always be green only. if it is orange, flashing orange, or even red while your console is on and in
operation, it means there is a problem in the power supply or the outlet itself or you have too many things running on a current tap. if you get the three-red ring of death, check your power supply LED. i will bet it is orange or even red. meaning faulty
power brick. try another power brick from a known working Xbox like from a friend or if you got two, try your good Xbox PSU and see if it works. i lost one Xbox 360 due to the three-red ring of death followed by a completely dead console (the PSU failed and
took the console with it). for the longest time i figured red was just the color of the power supply LED, until it failed and as i was checking, discovered the color chart in fine print under the power brick itself. i had a weak and/or failing supply and when
i turned my Xbox off and right back on in an effort to reboot it after resetting my router, it killed it. i am unsure of everyone but my replacement Xbox has a power brick LED that is green all the time, on or off. i suspect that is proper, although my slim,
and it may be slim specific, has one that is orange when off and green while on. i would recommend checking your power supply light regularly

That is typically a fatal error and the console will have to be repaired or replaced. I don't think that MS is now repairing any 360 consoles that are not under warranty so if yours is not you will probably need to replace it. http://support.xbox.com/en-US/contact-us

Hope this helps. Good Luck!!
