Hello, Im new to this form and i hope somone here can help me out... I got a matrix infinty (1.38v) installed in my brand new pstwo(slim) last week, it was done by a technician in a store - so i almost certine he did a god job with the soldering, I also believe the chip is original, he also installed a laser protection chip - but i dont know any details about it. We checked the machine in the store and it looked fine. Few days later, when i had the chance to test it at home i found out that i cant turn the PStwo on, When i pressed the power button nothing happend (the red light flashes on and of randomly), Some times the PStwo will start for a few seconds and then shut down again (most of the time it wont even start). This happens regardles of the disk i put inside(it also happends when i try to turn it on with no disk, or with the tray open). I first thought the problem lies in the power cable (coz of the red light turning on and off randomly) but when I replaced the cable nothing have changed. I hope you can help me with my problem befor i have to go to the place were i had the chip installed (its far away from where i live). I should mention that the ps was bought in US and i live in israel, this is why i use an adaptor on the power cord, altough im sure this is not the cause of my problem. oh and, Sorry for the shitty english. fusk it. im not sorry.
