What if your screen have blue, magenta, and yellow cracks?
RCA tablet, and it doesn't work, because there are blue, magenta, and yellow cracks on the screen. If you can fix this, then tell me!
@robertb going by your description alone, it sounds very much like a broken LCD. To verify this post an image of what your screen looks like with your question. For that use this guide. Again right now it sounds like a broken LCD. It can not be fixed but needs to be replaced.
