Not a bad Trinitron, it's still better than a post 2000s set with digital processing.
Get it if the issues doesn't bother you, and the possibility that composite could appear a little noisy as if it is RF.

This has nothing to do with purity.
I know what it is.
Every modern CRT has a automatic cutoff control where the RGB amp limits itself to protect the CRT from voltage spikes in the signals.
Now some test impulses are inserted into the overscan and the tube current is measured during that time.
The measured current is stored/saved and used as limit.
My other Trinitrons with their Philips/STmicroelectronics chips (starting with TDA/TEA) have 4 test lines that are black, red, green and blue and the intensity is set after the contrast+brightness setting.
The KV-M1450D with it's Motorola IC (MC44002) has different looking impulses, they are insanely bright and get visibly reflected to screen causing that white stain.
But that wasn't my only problem with this set, i found out that it has a certain capacitance on the RGB input.
I just made pic related to demonstrate the issue, it's not so apparent in most applications but sometimes it stands out.
And the other problem that i have only with this set is that a weak signal is shown with a great amount noise on both composite and RGB, on the other Trinitrons it's just dark.
Not a bad Trinitron but i prefer my older KV-M1400D with it's ruined case, and have the KV-M1450D as backup in my attic.
And it a caused by the tube, both sets have the exact same one.
