Installed MODBO 4.0 and now no picture or sound

**mnk4ever224** · 03-02-2009,10:17 PM

I installed the modbo 4.0 on my 500001 v10 ps2 and it powers up, disk spins continuously but I never get any picture or audio on the tv. I checked to make sure no wires were touching or anything. Not sure what is going on. Please HELP!!!

Or you have the common failure. The ground wire is too thin. If so, replace it with atleast about 0,35mm wire. Dunno if thinner will go, but 0,35mm works for me

And there's one fuse that does this same effect if it's blowed, that i remember. I dont remember what fuse it was, but check the fuses. Their those small boxes, with PS1, PS2, PS3, PS4.... on next to it.

Thanks, I will try it tomorrow. I did use 30 AWG on all connections! Just the ground wire needs to be bigger? (or does the 3.3 Volt wire need it also?) And any clue as to why the reset button will not work? I am desperate.

I really want this to work because I have already broke the leg off of the circuit that the 10 wires attach too on the PS2 slimline 790001.

U should use thick wire on power (+3,3v or +5v depends on chip) and ground
