(adsbygoogle = window.adsbygoogle || []).push({}); Turned on ps3 slim got no signal, so I turned it off, turn it back on and signal worked, went to gta v played for a about 20 mins, I went to Quit Game to play another, and The PS3 had Frozen, It wouldn't turn off so I unplugged and turned it back on and no signal once again, I tried letting it sit for a long time and same thing occurs, I tried formatting the HDD, entering recovery mode but no signal pops up, and new hdmi cables even a AV Cable, I just got this ps3 about 5 days ago, downgraded it and worked fine, but then this starting happening, it all ended up like this when I tightened the heatsink clamps the right way because I had them upside down, please help, thanks!

PS. I tried the 4 penny trick and did not work!
