Geetech A30 break down looking for some help

[zekgrafic]

so i went to start a print and the touch stopped working, i could get it to change the screen with error codes but still couldn't use the touch screen
i did some research and was pretty sure it was the drivers so i installed new drivers, then i turned it on to a blank screen (no on pixels) but it still beeped when i turned it on, so i changed the stepper drivers (thinking i mixed them up) then i put one in backwards by mistake and turned it on and wrecked that driver and now it doesn't even beep when i turn it on. (i was gonna buy a new power supply touch screen thing but i would like to know if this is salvageable?)
