Looks like the box has died on me. :emoji_angry::emoji_angry:
Power lead working fine but box will not power up. No lights. Nothing.
Anyone have any idea's what it might be?

(ps. my lad has just informed he plugged a different power lead in by mistake and its not worked since) Obviously something has blown. What would have blown and is it repairable?

Thanks

Oh crap might have to go topless to see as circuit board could be fried.
Hmm 12 volt power supply is the + feed in the centre or outside of pin, and what power supply was inserted?

Go into the box remove hard drive if fitted try then to boot the box
Also inspect the board inside for damage / burn marks
There may be a fuse inside i can't remember

I have removed the board and can’t see any burn marks. There is no fuse anywhere. That’s the first thing I checked. Have not removed hard drive so will give that a go.

Ps cactikid. Not sure what incorrect power supply was inserted when it blown. Dumb Son did it.

Might mention now as every time one buys a new electrical toy is to write on plug in white/black marker what its used for and not end up with a drawer of unknown power supplies as none are standard as one finds out later.
Tv repair shop could check it but if boards are gone might be toast,maybe contact wos for help if bought from them.

Sorry for the slow reply iv’e been quite occupied today
Ok fantastic photo’s i have had a good look and i can’t see any blown components
I would check the continuity of the surface mounted fuse F3 this is located behind the power socket inlet, also check the continuity of more items behind the power socket
Are you sure your psu is working correctly needs to be 12v 3amps ?
Did you try the box with the hard drive not connected ?
I hope your lucky with this one
