Switch powers on but leds remain black and i cant console into it the screen just remains unresponsive

I have been searching the manuals and there is nothing i can find about how to troubleshoot a switch that doesnt pass or fail post.

i am just looking for some info on how to troubleshoot the actual hardware of the switch and what to check inside it

I have tried the power and rs232 cables on a router so it isnt the cables

I just need to know if i have to send it back or not because the guy said it worked who sent it to me through ebay
