Service Manual for LeCroy 9310M - Video issue

[lincoln]

Hello, I'm trying to repair a LeCroy 9310M O scope. The video display has no vertical sweep. On the display driver board I found this carnage: http://imgur.com/a/7tdiR#0

I think I have identified all the bad parts but I would still like to see a schematic to try to figure out why they blew up. Dose anyone have a service manual? While it specs are pretty paltry by today's standards I would hate to see it junked.

Thanks!

Interesting pics.
Hard to say what went pop first, maybe the cap?

Check a few around to see how far the have drifted from labeled values.

Hope somebody comes up with a manual for you.

Got it fixed:

  It looks like the cap shorted when it blew and short circuited the other components.

The video board was used on several of the 93 series. While I was eventual able to track down a specific manual, all of the 93* show the same video board. The board I have was a newer rev then the service manual show. It could be stuffed to fallow the the older design but the service manuals did show the transistor/trimmer that blew up .
