Xbox 360 Slim It turns itself off

Hi, I have this little problem with my Xbox 360 Slim, it goes off alone and I do not know why, it all started about 3 or 4 months ago where I bought a generic or generic source, and it broke down and not long ago it was in November I bought an original
and since then did not turn off, well, since Monday, I started to turn off again and I do not understand why, but after about 5 or 7 unexpected shutdowns it does not shut off and it works 100%, but also on turning it back on and noticed that the resolution
of 1080p to 480p is lowered and I do not know why and I would like to know if someone has an idea or what they might have,

Thank you

:)

 

Xbox 360 Slim turns off by itself

Hello, I own an Xbox 360 Slim 4GB that I bought in late 2011. The problem with it is that every time I turn it on it turns off randomly by itself. Like sometimes it turns off right when I turn the console on or it would turn off after a few minutes of keeping
it on. So for my Xbox to stay on I need to keep turning it on repeatedly until it stays on... eventually it would just stay on so that i can play or watch netflix... But I still don't know why it turns off, like if it was haunted or something, the xbox looks
fine and the power brick is fine too, it has a yellow light when the console is off and a green light when its on. The fan still works so I don't if its overheating because I know that can cause video game consoles to turn off. I keep it on a wooden surface
which also holds my TV and the xbox has space so nothing is blocking or touching the xbox. I tried cleaning the power button with a ear swab because i know it could hold fingerprints which could mess up the calibration. This problem started this year like
around February and I'm sure it doesn't have warranty anymore because i bought it 2 years ago. So maybe anyone has any thoughts on how to fix this or if you have the same problem. Please reply

 

XBOX 360 Slim Turns Itself Off Unexpedly

There is always a risk involved into buying pre-owned, refurbished consoles for you are never aware of the way the console was maintained from its previous owner and its life expectancy.

Xbox service will not be offered for your console and you can't even ask for a replacement since you opened the console thus breaking the warranty seal.
