Exactly right Julie, I meant UE9 and UE10 - not the first time I've mixed those up with something else. UE9 - UE10 are the ones which sit in the read path from both the screen RAM and the system RAM. I am sure those have not been replaced, as Colin just seems to have confirmed.

Colin, may as well put R41 / R42 back as they were. If you want something to occupy you in the meantime then, if you feel like doing it, replace UE9 and UE10. I know you already have the ICs.
