    I have a problem with PS One LCD screen (NTSC-J). PS1 fuse blows right after start. By checking the PCB for a short circuit, the DP1 element (CII 133 ZHU) warms up. The element looks like a diode, but I do not know what. Does anyone have a schematic of this PCB?

    "When a fuse blows it blows for a reason. Bypassing it is just asking for trouble and so long as you don't mind likely killing the screen bypassing is a fine idea."

    Don't replace or short the fuse without troubleshooting the board.

    There are no schematics available for this design as far as I know. That is definitely a diode though, it looks like a 1-2A shottky would do the trick.

    I'm also looking for a broken one of these for parts.... If anyone wants to donate....
