My power bot is just blinking when I try to charge it. do you repair?

I have a Samsung powerbot and it just stopped working one day. I have tried to replace the battery and the charging station but it does the same thing. When I move the powerbot to the charging station by hand, it starts to blink when on the charger. Then after a few mins it stops and will not charge. I am unsure if it is a fuse or what but I am looking for someone who can help fix it or someone who will repair it. I have contacted Samsung but they company they refered me to does not do repairs. It is just over a year old so there for my warranty is no good any more. Is there some place that will work on them or is there someone who knows how to fix it?
