U25 has jumper from pin 17 to 24 and trace cuton pin 17. r251 removed 3.3k between u40 pin 11 u44 pin12

Do you mean U29???

Whay voltage do you have on pin 24?

[t-rack]

went over some shoddy solder joints, now have 2.5vdc at pin 17 and 24

yes u29 sorry

still no display or sound

Sorry,missed your reply.Anyway 2.5V is waaaay to low,you should have 5V on pin 17,11,24 and 25.Also check the voltage on pin 28 and 26 of the eprom,is this 5V or also 2.5V?

[t-rack]

i know its been a while but im back at it now, 2.5v on pins 26 and 28

Ok measure the voltage comming out of the voltage regulator VR4,between pin 2 and 3.Should be 5V.
