    Well, they are not offered much at this time.
    For the time being I've found only one seller Satking in Germany with an original psu for 45,15 £ .

    Yeah, that's expensive, but it is a original and mostly better than the clones.
    But I could send you a good tested but used and repaired clone psu if you like.

    Just send me a private message for more info.
    See the contact option beneath the avatar image.

    Thanks for your offer but i'm back up n running again.

    The 4 caps tucked under the heat sink were discoloured and bulging, so i ordered up some 125 °C ones and replaced them.
    Then i decided i might as well replace every other electrolytic cap on the board as i already had these in stock at work. Many of which i managed to replace with a slightly higher voltage cap.

    I tested the 2x SM transistors Q200 and its neighbour, and these were ok. (mine are labelled as Y1 devices).

    The box fired up instantly. Where i used to have to wait 10+ seconds to get the bootloader screen.
    Hard drive and fans running again :)

    Yes, it is often related to the caps.
    If I knew that you were be able to do it yourself, I would have given also this advice.
    But luckily you have already got the idea to replace the caps.

    Anyway, thanks for posting your message, it's always nice to read that it is been solved.

    Well done :)

    Hello JOKINN,

    Johnny worked a lot on the PSU of the DM8000HD, and you have his comments and help, photos about it on the forum link below,

    http://www.ourdreambox.com/ubbthreads.php?ubb=showflat&Number=1592#Post1592

    With that you should be able to know which version of PSU you have, as there is 4 + 2 + 1 caps to change, and the last one depends of the version of PSU you have.

    The best are the 105° and even we found 130° ones (but very expensive), don't use lower ones like 85°,

    Hi, I made replacement for this PSU based on MeanWell power supplies. If anyone is interested in I can make some PCB for it to make it more nice. But the price will be arround 60 EUR + shipping.

    If it is not caused by a tuner, then it may be caused by the psu.
    I had tested the psu, but unfortunately not with four tuners, but with only three tuners.
    If you want another psu then you need to wait because right now I have no working clone psu's, I need to repair one.

    I expect, after the weekend, but if I have a psu working then I send it directly.
    And of course a pm message that it's underway.
