Shawn,
         I will send private, jpegs of sweep, waveforms and setup menu.
I would check and recheck all caps in power supply, sweep supply and vert
output. before getting inside of the 9-700 module.. Note on 9-700... running
set with cover off, will display a very poor picture....
Email if you need more help..
Bob,
