Hello minder when you say reverse engineering how do you mean
All I can tell you is that it works on 6v system and as far as I can see there are only the 3 components damaged I have not tested to see if the are giving continuity with my meter as yet and the only numbers visible are on the 3 pin...
I’m trying to repair a pcb for a friend bu tv need to identify a couple of components that have been damaged. If anyone can help. Position U27. and U28
Thanks. Paul
