Symptoms:
Color ram appears to be bad during the self test.
Repair:
I desoldered the two 6116 rams used as color ram, however they appear to be good.
This probably means an IC related to these rams is deffective.
However, i will have to put socket both and test with other rams so I can be sure they are working before testing the other ICs.
Found a bad 74LS245 @ U14
Actually, replacing the 74LS245 @ U14 fixed the problem
