No response from my Crown cdvdrw300 dvd recorder?

pls can anyone help me I was recording a t.v programme and in the middle of recording it just stopped for no reason at all my dvd recorder is a CROWN CDVDRW300 the power light on the machine is still lit when plugged in and goes off when unplugged but other than that i'm getting no response from the machine itself tried different batteries in the remote control in case it was that but its made no difference tried switching it on by the power button on the machine but getting no response from that either. please anyone with any ideas will be well appreciated thx.
