My tablet will not turn on like it's all black I put it to charge and nothing still in total darkness not even a light I have

Screen could be dead, look into a replacement screen. For cheaper tablets it will likely be cheaper to replace the device than pay to get a new screen put on.
That's if the system seems like it's turning on, is there a power/charge light that goes on and just the screen is black? If the charge/power light is also off, the battery of system board may be bad.
