If the frequency is off you diagnose the sweep stage, if frequency is OK and you can get a single image that floats in both axes and can be made to roll both directions with hold adjustment you diagnose the sync.
Most sets horizontal is fairly easy to get on frequency by centering the hold pot and adjusting the synchroguide coils for correct frequency (for sync or single floating image if no sync from separator).
Also if you are using HDMI to AV converter that supports both NTSC and PAL or component video that supports progressive scan and resolutions about SD make sure your sources are configured for SD NTSC interlaced.
