lecroy 9310am (video board problem)

[radiopierre]

Hello all , I am new to this blog and wish to all best for 2012 ( its not too late).
I have a Lecroy 9310am and when i powered the scope the first time the video  board( EC-0813030B-4) Resistor  R313 blew i changed the resistor and verify the capacitor C308/310/305 its all ok.  i have received the service manual but have not found any schematic of the video board in order to verify what else would be defect, but was not able to view the specific schematic . I have verified with someone in germany who had the same  scope and - video board and  that work perfectly with my scope . I wonder if anybody had same experience and or detailled schematik for that little video board or any tips that could fix it. Appreciate any help  regards . Pierre
