Hi,

I have a dead CRT from Iiyama but all parts are manufactured by
mitsubishi.
Symptoms : After power on, the screen light its led for 1/2 - 1 second
then turn off this led.
After a little investigation, I noticed that when I unplug a cable from
the main board (near a microcontroller) to the little board connected to the
CRT, the led stay on.

Anyone have seen this before ?

Perhaps some of you have an appropriate schematic (or service manual) for
this screen or for the same type of screen from mitsubishi.
