Unsoldered pin 54 of U1001 thinking it might have been pulling it down, no change, Q4105 is supposed to be the 5v standby source? (no schematic) I have ( measured to cold ground) E= 4.77 B= 5.1 C= 11.7 volts. Could the 4.32 be too low on pins 8 & 5 ? I was told pins 5&6 get the 5 volts from pin 8 of U3201 so I`m still confused how pin 5 can have 4.32 but pin 6 would be zero if the source is internally from pin 8 even with a new eprom installed, HELP!!!
