I got a PS3 Slim 120 GB yesterday that has an annoying problem. When i plug it in, the LED shows up red like normal. When i try to turn it on, the LED goes green for half a sencond then back to red. And i can hear it tries to beep but only for half a second too. I opened it and tried without the BD drive and the HDD but it does the same. I opened the power suppy unit and tried to play with the potentiometers, still without success. Do you think i need to try with a new power supply unit or could it be the motherboard?
Thanks in advance for your help
