Ikegami 9 inch color CRT production monitor, no picture

[Chip Chester]

Like old tv nut sez, forget the F connector signal (threaded one). You want the yellow RCA from the VCR to go to the composite input BNC of the monitor. You won't have an SDI source from a consumer VCR. Your monitor will use the same BNC style connector for analog and digital inputs.

In addition to plugging it into the right input, you'll need to select that input for viewing on the front panel controls. You also may need to terminate the loop thru connector on composite input with a 75 ohm terminator. If there's a termination switch, use it to terminate the connection. (Some later Sony's had built-in terminators, but manual would mention it if this monitor had it.)

Also, if external sync is selected, it may not show a picture. Deselect external sync on the front panel switches if you're not supplying it external sync. (You have no need to set up ext. sync when watching a consumer VCR.)

Post a pic of the back panel and front switch panel (with labels legible) or a link to the manual if you have more questions. I think if it was working before, it's probably just an input/switching issue that's keeping it from working now.
