Hey
Í'm trying to repair the powersupply in a MX3500.
I think the fault is caused by by the TR1. I'm having some trouble trying to find a replacement. Do any of you know any cross reference to the BUT12F transistor?
Update: Seems like BUT 76 is a good replacement, http://www.datasheetarchive.com/crossreference/BUT12F.html.
Below you can see some photos of the print. The inductor L5 has a black hole around one of the pins.
If you have some good advice on this fault, please let me know.
