Hello,
I have a T2 and I am getting the game reset error that happens when the cpu board is not gettin the 4 volts it needs to save memory. I changed out the battery pack and replaced the D2 Diode and I am still getting the error. I am getting a 4.7 volt reading out of my D2 but I am not getting any reading out of U8 chip (which stores the game memory). If you can provide any feedback. thank you!

When you turn the machine on how many times is the LED @ D20 flashing?
I would assume twice?
Reflow the RAM socket as well. It is possible you have a broken trace or possibly a defunct 2064 IC?
