How do I replace the cracked screen on my Proscan PLT7810K ? I would like to fix it myself, it still powers up when started.

If you have rooted your tablet you will have to unroot it for it to update

Hi try this plug in charger & hold down power button for awhile it might reset.. Cheers

Proscan is classified as a bargain tablet in the low end range.so you should expect any kind od issues related to it. like that of power button.
Obviosly you have a problem with your battery, though no way to tell "from distance" if it's prperly the battery or the charger... or both You haven't commented in your post if it works with the power adapter. Chargers can be easily diagnosed by measuring output with an electronic tester. Once you have a good charger, you should test if you can charge your battery.
I understand that Proscan batteries are "lifetime", so it's not easy to replace them.
You should evaluate it it's worth to buy new charrger and replace the battery or maybe buy another device. Probably you need some technical assitance for diagnosis.
Take note that you can get a used tablet from Amazon from about 465 USD in good conditions, without the need of spending on repairs
