I Want to Fix My Ps3 but I Dont Know How?

ok so i my bro brought home his ps3 and i wanted to play it nazi zombies and then when i turned it on the screen wouldn't come on so i really need to play
it will not come on
when u turn it on nothing is on the screen the system is running but not the screen
i even checked the channels
p.s. we dont want to ship it or bring it some where to fix it…

Suggestion:

Easy peasy. This one got me for a while too.

1 – Make sure the PS3 is off and the TV is on
2 – Press and *hold* the PS3 power button
– - It will beep once when it turns on then about 5-10 seconds later it'll beep again
3 – Release after the second beep mentioned above
4 – Wait about 5 seconds for the screen to come on then kill some zombies.
