No Power Supply

I am using a Ricoh Aficio 2035e copier, it suddenly went off about 7-8minutes after turning it on. i tried to to swtch it off and then back on using the power switch and the only thing i could see was the green power saving mode light flash once. i thought it was on power saving mode so i pressed the power saving butter then i saw the green light flash again.i went on and opened the side cover of the machine so that i can check on the power cord and it was securely plugged in the wall outlet. i also checked the power supply board if their was any blown fuse or capacitors and i still couldn't find any blown fuse or capacitor. and now am out of ideas.Thank you in advance for your help.
