I have a HDTV and bought a HDMI cable to connect my PS3 to it. It was hooked up and working for a couple of months with no problems until I unhooked it to take it on vacation and left the cable behind. I came home to rehook it up through the video output seetings on the display tab. Unlike what I hyave done before the screen went blank for 30 seconds. I tried reseting the playstation, changing out the cable and checked to make sure everything was plugged in. I’ve done almost everything that I know of except doing the factory reset which would erase all of the saved data. I need help to know what to do!
