Thanks for the reply
Yes it's a Ad8629 chip I have replaced it but still no change there are relays on the main board and thought if one of them my be bad but it passes the self test and you can hear the relays clicking so not sure its crazy I feel like I am just missing something simple just cant seem to find it I have checked the mov, ptc and change the resistor network as well
But I found a bad switch ic uln2003 that was blown I have changed the c072c,and Adg412br as well and the ds75 just for good luck still no ac readings, let me explain it switches over the that mode and I get the random digits but not any correct response it acts like the signal isn't strong enough to register if I increase voltage there is a response up or down just not in the ball park it's all millivolts example 120vac I get 8.6 millivolts hope that explains some of what is going on with this meter
