    'latest vix couple of months back' could mean anything.
    Menu -> Information -> About will give you the actual build number & is a lot more helpful in diagnosing any issues.

    Obviously you can't see that sreen now though?
    Have you tried a bootoader flash along with image flash? latest available on http://www.openvix.co.uk/

    Red light on boot up does sound like capacitor issue though.
    Try bootloader & image update first before you get the soldering iron out...

    Going by the age of the receiver i'd say it's very likely the infamous capacitor. There are two tutorials on the forum that go into great detail on how to replace this cap.

    Don't power on the box before you replaced the cap, otherwise a (more expensive and more difficult to replace) IC will be blown.

    Help asked via PM will be ignored.
    The forum is there for help and all will benefit from your questions.
    NO CARD SHARING TALK WILL BE TOLERATED, LAN OR WAN, IN OPEN FORUM OR PM !

    This is the capacitor fault for sure. Red light with no box booting. Only Hdd is spinning.
    Capacitor C807 (on motherboard) 220uF 16v should be replaced by a new 330uF 16v (since this has a little more headroom for power).
    I easily replaced this myself. A tip for a clean but not that neat looking job, is to just cut the leaders close to the old capacitor with a plier
    and then use the old capacitors leaders to solder the new one back on. Remember to get the + and - right :-)
    Don't look like a pro job but it works with no risk of overheating the motherboard and its circuits.
    (Not the best English either...)

    The capacitors are there. SMD (Surface Mounted Device) types are used.

    You can try, but issue could even be the PSU.
