Ps Vita not working so well

[Atomikaso7]

Hi everybody!
I had been having issues with my ps vita since I left it one month without turning on between February and March. Stayed for very long without responding to the power button (I replaced it but still the same), but when plugged the orange light went on. I also replaced the battery. Suddelnly one day, I attempt to turn it on and it turns on, but keeps turning off while sleep mode or even when I'm playing, and goes back to that "stubborn to turn on" status. Everytime it happens and gets to turn on again the console asks me the hour and date. I think that should be a problem with the motherboard (tried to disconnect both buttons pcbs and it still acted like this), this bit seems to be corroded and when I turn on the screen the home button blinks for no reason. It's very frustrating because I just wanna play to my ps vita but this problem won't let me  :(. Thanks in advance for any help onwards.
