Have a 820-3787 that has distorted looking apple logo when loading and once loaded login screen only shows couple seconds as seen in pictures but the going to just backlight only shortly after.

works fine on external. Test known good lcd was used and still same issue.

what to check first?

Just curious does it look like it?s been previously repaired? I had one just like that where the CPU died from doingthe FDMF fix...
