Apple III video issues

hello i just joined this forum in hopes to get my apple III working again.

 

i have what i believe to be the mem diag screen. however it takes up the entire screen and is mostly random garbage. 

however if i remove the ram board completely i get a solid white screen.

 

i have tried reseating all the chips on the motherboard. and i swapped around ram chips to see if i could atleast get it to display a normal mem test. nothing i did changed it.

the on light on the keyboard is also working.

 

does anyone know where i should start looking?
