can u describe the nature of the problem.... 20 times?

i m sure u hv asked seller for help and concluded it's power adaptor failure.
i have seen 2 cases of such failure myself... some other brand.
i just replace with new adaptor... rm20 or so, done.

adaptor failures... hard to say what caused it... rm105 box... cannot expect it to be top notch quality, can also be lightning, accident?
a sad case for u since many of us bought from this seller, no one else reported such a problem so far.

there is a reset pinhole like other boxes to do factory reset.
but i guess he already checked it with seller or tried himself.

u can read more about the seller (and other sellers) here:

as far as i can tell, all buyers except one is happy enough.

but it's a free world - one can praise or one can condemn - even in a public forum.

anyway, i think enuf said!
