Dim CRT and color isn’t bright

[glay78]

This is a Mac TV, I replaced the analog board with one from LC575 and the CRT is dimmed and color isn’t bright and vibrant. Is this due to the analog board or the CRT (too used)

I’ve tried the settings and they aren’t. Settings as in the analog board adjustments.

What was the condition of the CRT prior to the analog board swap? Have you adjusted the pots on the analog board for brightness, and sometimes there are additional dials on the flyback itself.

My experience with high hour CRTs is they can be just as bright as usual but dim when a bright image is displayed before slowly becoming brighter after a number of seconds.

The analog board that comes with it has shorts and kept blowing fuse, so I bought one. Tried all adjustments on rear of logic board. It seems like a dim CRT itself as it powers up very dim and slowly gets better in few minutes. But still dim
