Android M8 tv box blue light on nothing else

[sam1]

Hi anyone have any ideas about how to get my M8 box working again.Started having some issues with box taking a lot of time getting into home screen.Once in the picture would flicker in and out and say no signal .After i unplugged the box a few times it would work properly.Now all i get is blue light on the front and nothing else.Have tried different HDMI cable and also plugged into another TV but still no go.Is the box no good or is there a way to get it back running again.Had a look inside to see if it says anything else about the model number but i do not see anything .Had the box about 2yr and worked flawlessly till now.Tried the reset option but no luck.Thanks

Have you tried a different poweradaptor?
it this a s802? Or s812 ?
for more help.. A pic of your pcb might help ( or pcb version number and wifi chip version number )
Yes, this means opening the tvbox enclosure.. sadly ( screws are most of times under the rubber pads )

goodluck
