i have a ps3 with the blank screen prob. well i did....... its now fixed. like most on here when i turned my ps3 on it had no screen or anything. i tryed all the simple do it your self fix like holding the power button down till it beeps. and all that. i even tryed the hidden reset button. on the controler which you will need a pin to do. its a small hole on the bottom of the controler by the with out looking right now L2 button?
anyway how i fixed mine was i took it apart...... just to see if anything had come lose. striped it right down could not see anything? so i put it together again and hay it worked but not for long it would not take a controler, as when i tryed linking it up my ps3 froze. then i turned it off it was blank again.??? awwwww i fixed my ps3 thesame way you would fix it if you had theYLOD. it turned out to be the chips on the motherbord...... i had to set it up again thou in the menu. when it turned on. but it now WORKS.
I never had a problem, manualy starting the ps3. It just takes a little knee bo grease to get up and do it.
