Tablet screen not displaying, but working with HDMI
My Switch system works with my TV screen, but the tablet does not display image. The touch and everything works fine, except that the screen only lights up in black (not the same state as if it were turned off). I'm assuming this is a hardware issue and not a software one since it works perfectly on HDMI. Specifically, I suspect the LCD component's cable is loose or the LCD component itself is broken.
Would you all be able to help me diagnose the specific problem? I am not familiar with how a broken LCD behaves, does it still shine light but only black light like mine? Is it just the LCD ribbon cable that is loose? Or might it be a software issue?
I've seen LCD replacements on ebay and I have seen videos and guides on the replacement, so it should not be a problem to replace it. However, I want to make sure the LCD is the issue before purchasing a replacement.
