[sdiy] TEK scope issue 5110 ---screen only works in the far right !

[cheater00 .]

Ask on the TekScopes mailing list. They will know. It's likely a shot
plugin (they're not called cards). Try another timebase. If you don't
have another timebase, but have two vertical amplifiers, put one in
the timebase slot, which will configure your scope into XY mode. This
way you can also check if the mainframe itself works okay or if the
horizontal deflection is shot.

When posting to tekscopes include photos of your plugins and scope and
include model numbers and serial numbers in the message text.

Cheers
