Hi there,
So far i have drawn a blank.
I have a a/v group Sydney Australia (cant find them on the net) Audio and
video 4 input switcher model av4swr as supplied into Austrar buildings.
I am trying to locate a circuit and board layout. I have seen several that
have a damaged u37 (some sort of Logic chip) that was likely caused by
power supply failure of the main smps filter cap. Then u37 goes up in
smoke. Anyway i am trying to locate a helpful tech and any contact that
might be able to help in information to
1) repair some by supply of the chip (version 4.2 software)
2) modify a working one for single button switching (there is an enable
button normally required to be pressed b4 sw can occur.
So any help there guys??
