Need repair advice

Lotta RAM swapping solved the problem although it didn't fit into any of the screen shots. Thanks and sorry for not FAQing the group. I was afraid it was something else that would be spotted by the wise eyes of the TI masters.

Was the problem a single RAM chip or multiple?

Advice to find defective ram chips: If you want to find a defective RAM-Chip set a good 4116 in piggyback above each chip. If the error is gone you are at the defective one.

But you should test if there are more ram chips defective. Watch out that you put the test-ramchip in the right direction on the others.
