Was playing rugby world cup 2011 today when some random fuzzy lines appeared on my tv screen, i switched my ps3 off straight away as i though it needed a rest and, ever since, am unable to use my ps3, im using a standard 30" sony tv with standard yellow, white and red cables. I've tried the beeping process on the ps3 and also the powering down process, nothings happened as it's still showing no display or sound even on HD. Please help :P

I posted to your problem with a similar one. I was able to get my PS3 to work by:

1.) Powering down both the PS3 and ViewSonic LCD
2.) Unplugging the power cables to both PS3 and LCD
3.) Waiting at least 10 or more seconds
4.) Plugging in the power cables to both PS3 and LCD
5.) Turning on the ViewSonic LCD
6.) Turning on the PS3 and holding down the power button until the beep

After this sequence I heard the bootup audio and the menu appeared on the screen- which detected the HDMI connection to my LCD.

Very odd.. I've had my PS3 in the same place for months and just today this happened.

I wanted to post my success. Best of luck!
