I have a very old PS2. It worked fine for the longest time, but recently I have a strange problem. Every time I turn it on, no matter which game I use, it acts as if I am holding the analog (or possibly d-pad) left.
As a result, the only thing that works is pressing Start. When I manage to load a game (by just pressing Start repeatedly) the character spins around ceaselessly. The only other control that works is the other analog stick.
This means that in Tony Hawk games, for example, I am constantly spinning in a circle. Using the other analog stick I can observe myself spinning from above, below, or any angle in between, but I can neither stop turning nor change direction using the other stick or d-pad, and as I said, no other controls work.
I have tried turning the machine on with the controller in slot 1, in slot 2, and not plugged in at all. Nothing changes. I followed the instructions here:
... although the fact that this is happening even when no controller is plugged in makes me think it is not a controller issue. I am even more sure of this since I went out and purchased a second-hand controller today, and the situation has not changed.
Borrowed another controller, a non-Sony one this time. No difference. Also took the PS2 apart and cleaned it as best I could, tried inspecting for damage but as before found nothing obvious amiss.
Is it possible this is a software problem? Corrupted OS, maybe...?
In desperation to get a Tony Hawk fix, I tried PCSX2 (the PS2 emulator for PC). While in the process of hooking up my controllers to the PC, though, I ran a test and discovered something curious:
One controller is sending constant buttonpress signals for all buttons all the time. The other controller is sending a constant signal for just one buttong (d-pad left), again all the time. Taking them apart and cleaning the contacts had no effect.
I think I need to consider the possibility that both of my controllers and the one I borrowed for testing were all, unlikely though it is, malfunctioning. The system is certainly acting as though a button is being pressed all the time. The fact that it acts the same even with no controller is hard to explain away, though. Just wish I had another PS2 to check with.
