Hi everyone, my kids knocked my 24” 2009 iMac off their desk horsing around and ever since the display is wonky donkey. At first I suspected gpu and did have a compatible apple spare in my junk which is what is powering the mirrored external screen below.
The machine works as it should via the external monitor. I suspect at this point either the lvds cable or the lcd panel itself got jacked in the fall. Any thoughts or common sense tests I am not thinking about that could tell me which one?
