So today my PS3 suddenly died. No LEDs, no power nothing. Not even Standby LED light. I thought it was time to do some basic checks. Like checking PS3 power ribbon and PS3 power supply. Power ribbon is tiny band which connects the front panel as i saw some videos on youtube. Mind you that my PS3 already has some problems of pressing power LED sensor. Sometimes i had to hardpress on sensor to switch on/off the console. The console works on/off normally by PS3 controller PS button by the way. Anyway, i checked Power cable. It was working ok. So took out my screwdriver other stuff to disassemble PS3. Just as i was disconnecting power cables. I tried one last time. And LED lights suddenly came on. PS3 was starting as normal. Everything working ok. I will do some more testing to make sure. But what just happened? What things i need to plan for servicing in case trouble comes back? Edit - Temperature and Fan speeds are acceptable and okay. No problems there.
