  1. 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.

    I took some pictures : http://lerhu.free.fr/iiyama

    Thanks,
