Hi Jayw,
 
Thanks for your response..  I know tek used hybrids in alot of scopes, what part of the ckt are these CCD's used in, and what does the CCD stand for, charge coupled device?
 
Thanks,
Ryan

Hi Ryan,

These scopes had a high failure rate in the CCD hybrids. It is likely that on or both are defective. You can determine which using the extended service diagnostics. (Or looking at their output with a working scope.)
