    Voided warranty for no reason.
    Thank you you´re very helpful with your opinion, but if you don´t know why i dont claim for warranty please don´t judge.

    If you have an ohm meter you can check them for shorts. Also, the fuse will typically open.

    Not worth fixing from an economic standpoint. If you still want to try to repair it about 5% of the time the CM600 chip will also fail.

    Here is a link to the CM6800 data sheet:

    Oh ok thank you so much i will read that pdf

    The primary side would have maybe 2 amps going through it, so the heating I^2 R would be 1W which seems very reasonable; so 0.27Ω is probably the right value.

    Be careful, the DC around there is even more dangerous than the mains.

    Thank you for you´re answer i will be careful
