I'm repairing (in theory) a 3 year old monitor, ie far more recent than my
own, so unfamiliar territory.
It uses an NT6827 on screen data display generator and LM1269NA CRT
controller.
The NT6827 is loading the 5V rail and tripping the protection circuitry.
Should be maximum of 25mA at 5V but putting a dropper in line it is taking
70mA when dropped to 3V.
If I disconnected this IC would the monitor work at a basic level or default
to zero brightness etc?



Try it and find out, have you checked on the price of a new IC though?
