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

Thanks for the info guys,
I'll be out of town over the weekend, I'll try to get the part next week.
If you know of any things that might sneak up on me with this ps let me
know. 15 years ago I fixed a lot of Philips ps, often you had to put in
the ps kit not just the one bad transistor/diode you found. Hopefully thats
not the case with the Sony.

PS. I repaired 11,000 vcrs, but none in the last 15 years.
I got out of them when the price hit about $200 :-)
