Ok I'm back
I invited my mates to my house and asked them to bring both boxes here and one windows PC.
First we try to reføash the boxes with NFI original image but with no success, so then i open up my UNO took out the PSU from this one, added this to one of the damaged boxes but still red light comes on.
we tested on second box and is still the same problem red light stays on but no life on the box,
i then try both PSU from damaged boxes into my own UNO and both of them work perfectly
So in the end we come to the conclusion that there must be a problem with BH image, or some capacitors that needs to be changed.
Im sorry for my mates and actually give them 2 of my own boxes as I'm not suing them right now, and hope for a solution so they can fix their boxes.
this boxes are buy from Germany some time back including 2 of mine, i have no problem with mine but my mates are.
I wish and hope some cleaver guys can help, i wish that VU+ will replay to how we can fix this problem,
Seems there is no help to get from the German distributor as he do not accept use of third part images as he called BH, if we had Original image and this had happened then we have full warranty, but since we have used BH we have nothing it seems
There must e a way similar to DUO that buy replacing one capacitor the DUO works, this could be possible for UNO to, it is just that we do not know how and what to look for.
anyway thank you all that try to help out
