Hi all,
I have a dead SLV-778HF vcr.
The switching transistor tests ok and all the diodes check good.
I found Q102 checks open. It is the driver for the switching transistor.
It is labeled C4040, it has a one last symbol looks like a 0 with a
horizontal line through it.
I have searched C4040 and 2sc4040 datasheet and didn't get one hit!
I'm pretty sure it is a transistor, the pcb is labeled B C E.
Any Ideas?
Mike
