Technika 42" on standby but will not turn on?

My Technika is about 6 years old now so may as well try fixing it myself. It has been off and unplugged for about a year now, and I decided to use it again, the blue standby light comes on when plugged in but it will not then turn off, it clicks and blue light goes of for a few seconds but then comes back on again. I have the back off and am standing by for further instructions please. Thank you.
