How can i fix M380?

We bought a Conia M380 through sale on newspaper. So we didnt get manual. It was operating good for almost a year. But now there is problem that we cant switch the DVD on. The dvd is connected to power and we clicked the power switch on but when we try to use the remote to turn it on its not working. I even tried to change the remote batteries(thinking remote has problem) but still didnt work. Dont know what happened. 2 days ago we had a power surge and our lights went off(thinking will it be the problem)
