When I turn my ps3 on, there is no audio/video. I don't think it's a software update problem, as I was playing my ps3 about two/three hours ago. I turn it off at the back, chill for a couple seconds, then I turn it on at the front, holding my finger down, it beeps once for turning on, then there is one beep in the middle, then finally one beep and it turns off. No matter how many times I repeat this process, nothing works. After trying that several times, I'll turn it on at the front, not leaving my finger down, and it still doesn't display anything, nor does any sound work. I tried doing that, then once it was on at the back (still in standby at the front), I tried connecting a controller via a USB cable, and pressed the playstation button on my controller, still nothing happened.

hope your PS3 problem has been solved, and you can play it well, if not, you can have a try to change other consale, and you can get any CD Keys you want if you go to https://www.m8x.com, Games Gold and Games Items are available there, good luck to you

2 days ago i got the yellow light of death when the 2.50 update came out rendering my ps3 to a 500 dollar paperweight.
I contacted sony about my problem and my console is under warrenty so it would be fixed for free so it didn't bother me to awful bad
the are sending me a box right now but i have fixed the yellow lights on my ps3 myself and it works now without a hitch
What i did is i took my 120 gb hard drive out of my ps3, Slaved it to my cpu tower and did a full format of that drive
then i took my hard drive and put it back in my ps3 and it ask me for the system software 2.50 disk so i downloaded the 2.50 update off of the ps3 website installed it and boom my ps3 work like new
this worked for me so far and have been playing my console for 6 hours now with out a hitch
maybe this will work for some of u aswell

You need to perform a Firmware Update.

.,,.,.,.,. There is a worldwide issue with PSN at the moment:

We're aware that many of you are having problems connecting to PSN, and yes, we're looking into it. Stay tuned for updates. about 1 hours ago via web SonyPlayStation

the disc reader might has been damage

You'll have to update the system software for your PS3 for it to play blu-ray movies.

You can read about it here:
http://manuals.playstation.net/document/en/ps3/2_60/video/aacs.html

On that page click on where it says "update the system software" and then on the next page it will explain the different ways you can upgrade the software.

Cocodinaro,

It sounds like you're using a damaged power strip; however, this issue can be caused by a bad outlet.

Replace the fuse and plug the unit into a different outlet. If the fuse blows, you need to go to a video game store an purchase a new power strip.

PS3 is The amazing device by sony but it has some common problems like video/picture but no audio problem. Good news is that these all problems can be repaired with the help of DIY Guides, one such guide available at PS3 Repair Blog

PS3 may have been doing an update of some kind and you have interrupted it and damaged the system software.
You might be able to download the system software and install it back back it will most likely wipe everything saved on your ps3.
Not sure how to do this as I have never turned off the power during an update ?
Found this site not sure if it will help
as it does not explain how to install the software onto a ps3
https://www.playstation.com/en-au/get-help/ps3-system-software/

but this you tube video explains how to do it

Also you could have instead interrupted a need for speed update. It needs to update to play in network mode .

If you update your PS3 system, the system you may not be able to play without first updating the system software.
