Fluke 196 Repair Turmoils

I acquired a Fluke 196 Scopemeter recently. It would appear to be in decent condition, it powers on and the meter portion operates as expected. Unfortunately, neither scope channel works. I get no waveform on either channel, and the oscilloscope portion what I got it for, I have plenty of meters :). I was wondering if anyone had this issue before and could point me in the right direction for repair. After some google searches I found the service manual, and everything for power seems to be in order. Thanks for any advice in advance! Let me know if I forgot to mention anything important.
