*********************************************
are you sure the psu is ok and it's sending power to the box ?
do you have anouther one to try to see if thats the problem ?
i keep a old router power plug convert to 12v that has the same
end on it as the psu so it plugs in the dreambox
iv'e had a couple of clone 800's that have died but both
had both light at the ethernet light on but with the new sunray
800hd at about ?130 from uk dealers if it is the mainboard then
at about ?90 i think a new box is the best way to go

i had this it could be a faulty tuner, take tuner out and see if box boots.

if it is the psu then a new box will be hughly recomended

************************************************** *
why would you buy a new box if the psu is faulty
when a new psu is very cheap to replace. i would
only replace the box if the mainboard has gone bang,

Guys thanks for the tips
I powered the board up on the bench with my bench psu

It fired up ok

Strange cos the psu is giving out 12v when i tested it

So have to have a peek on ebay for a replacement psu
Think there about ?6

this will do the trick someone posted it here the other day
DC 12V 2A/2000mA UK POWER ADAPTER SUPPLY PLUG LED STRIP LIGHT FOR CCTV CAMERA

The PSU supplied with the box AFAIK is a 12v 3A supply, I personally therefore wouldn't go for something with a lower rating but you can use a higher rating, so a 4A or 5A supply would also do.

[dave11674]

yeha have to agree
using a 2A supply may pull it to its knee's

thanks for the pointers guys

Hi

For the 800 it has to be a 3amp lower will do it no good, the 2amp is for 500.
