    Hi friends! I wery bad speak english, sorry. Help me please.
    My DM800se HIG024 Rev D6 2011-07-29 sim 2.1 box was working a few days ago but suddenly stopped. I now have 4 LEDs on: D201, D200, D204 and D203 but no D202. No blue light or any LCD display. Not connect dreamUp (all version), work only pytty - log.
    The external power supply is correct, sim card and front panel work in another dreambox.

    I've never seen this,
    COPY FAILED!
    error output, as also all low ohm values to all the dc to dc ic's.
    But I have the idea that you have an issue with the 12v circuit, one of the parts connected to it.
    In any case, I think, check the ohms value from the 12v circuit.

    Thanks for the information!
    BIOS DM 500HD is the same for DM800SE? That's what I got on my BIOS. Đ•rror in the circle.
    Holder sim interesting voltage values

    I have Cypress CY7C68013A EZ-USB. She can flash the BIOS, or first you need to deal with the hardware.
    In the third figure with voltage errors according to the 12 volt circuit
    Johnny B. Where to get a drawing for check the ohms value from the 12v circuit?

    Terminal output, the beginning of them, are basically similar between the 500HD/800SE.
    As for the bios, because there is a issue with the 3.3v, and the bios chip needs it, it may not work because of it.
    But, to come back to it, after a good night of sleep..
    7 - 0
    6 - 0
    5 - 5,0v/301- 914 /wrong U1100
    4 - 3,3v/92 - 17744 /wrong U1101
    3 - 2,5v/33 - 45 /okay
    2 - 1,82v/28,9 - 30/okay
    1 - 1,2v/307 - 300/okay

    Seeing this, then you have a issue with the 5 and 3.3v circuit.
    Since the 3.3v side has the lowest value, and uses the 5v as input, I think it could be the U1101, or/also Q1105
    More about this, see this topic/schematic.
