Hello. Im getting the common error 7 code on the MPU system 9 board. I changed out and re soldered new u19 and u20 sockets AND also changed out the u19 and u20 chips with brand new ones. I am still getting error code 7! Game GI turns on but that's it! From what I read what was fixed should have solved the problem. What am I missing or what should I check next? Kind of out of answers. Thanks for the help.
