I've been using my DMS3 for about a year now, but recently I tried installing hdd-explorer. The install failed, so I reset the PS2. Now the DMS3 won't work and only shows a black screen when I turn on the PS2, but if I hold the eject button down to disable the chip, it boots (of course it will only play original games). What can I do to fix this? Do I have to get a new chip?
