No buttons working as usual in ps3 thinner one

My problem is i turned on my ps3 after 4 years this morning, but the results were shocking—instead of showing me a red light it shows a yellowish light plus the eject led blue light is also on at the same time.. how do I get it fixed? It doesn't make a beep sound after pressing the buttons, no affect on after holding the power button for nearly a minute... The controllers aren't working as well,,it is not charging ,and no change after the reset button on the controllers is pressed...Anyone help i love my ps3 alot!:(
