Guys,
Out of sudden my TX3 won't turn on. Same outcome when I tried with another adapter. The same adapter can power up my old android box. Does anyone has similar experience? What is the fix?

I bought the box from Shopee seller, Lingl***.my. It is still under warranty and the seller asked me to ship it to China for him to repair.

Do you think it is worth the courier fee and hassle to send to China for repair? Or, should I buy a new one?

Thanks.
