Broken +3

I have a +3 which is misbehaving.
It boots up ok and shows the usual menu screen (most of the time).
It refuses to recognise a working disc drive or gotek - it shows the drive as available but if you try to use it you get told to insert the disc. It does cat occasionally but if you try a second or third time it shows the insert disc error message.
If I connect a Retroleum Smart card it loads Manic Miner and runs it fine. If I try Exolon it hangs.
I ran the Smart card in diagnostic mode and got the following:-
If I run the inbuilt diagnostics I get the following:-
Sometimes when I run the inbuilt diagnostics I just get a flashing screen (which apparently also signifies a RAM error).
So I changed IC3 and it made no difference. I guess I could change the others but not sure it would help.
Where next? RAM controller circuit? If the RAM is showing a problem but replacing the chips doesn’t help it I guess it would make sense that the controller is suspect.
