The controller port of the ps2

The Cable could have a break in it, check to make sure none of the pins in the Controller port are bent and if all else fails you will need to buy a new controller port, but try a different controller before you buy a new controller port

Well what do you expect from nerf to make a game controler :S. Buy a regualr logitech or Sony ps2 controler.

Hope this info helps!

there is a loose wire in ur ps2...

get it repaired..

or if u feel confident open it up urself and chek the problem out

Maybe you need a new controller that happend to me one time.

Yes, you can buy a PS2 Multitap Adapter. I had the same issue and just picked a mulittap adapter up on eBay for $8.50

It could be the PS2 connector port.
1) Try cleaning it. Maybe used compressed air or just blow into the faulty connector port.
2) Something more challenging, is to maybe open up the PS2 and to search for any broken connections between the Ps2 controller port, and the Motherboard of the PS2. Use a phillips #0 or a phillips #1 screwdriver, flip the ps2, you will see all these tiny squares, pull them out using something sharp, and underneath them there will be the screws, also there are some screws located underneath the warranty sticker and another underneath the Info sticker, just probe the surface until you land upon a hole. there you will find the screws. Open the ps2 up and you will spot the connector and search for any broken connections. any broken links can be fixed just by using a soldering iron and some solder.( OPENING UP YOUR PLAYSTATION VOIDS YOUR WARRANTY).
3) IF your ps2 is still under warranty, you can send it back to sony, or one of their many repair centres around the nation( IF U ARE IN THE USA). If in another nation, you can visit sony.com and follow their instructions on how to go about with in warranty repairs

yep plug the guns in to the controller ports or one controler in one port and the gun in the other port go to calibrate to calibrate ur guns and ur off man good luck

Sounds as if it has been dropped .....or an impact to the controller port while one was plugged in. in some cases the in side of the port can become full of dust and dirt causing light rusting creating a loss of connection ...but an impact can break a small chip on the back of the controller port inside the machine , try cleaning out the controller port and check to make sure the metal tabs are clean and un bent.

Yes this port be changed out on a slim like the fatter PS2 version it is a complicated work and should be done by an expert technician only otherwise the tracks on motherboard will be spoiled.
One thing be sure before changing the port you check it if this port is physically damaged then only you can proceed otherwise you please compare the working voltages on all pins with your port 2 and sort out the fault because sometimes +5v supply missing or any diodes connected on port is short which can be the reason for this fault.

There is a problem with the controller port PCB. Either one of the pins have snapped or a component on the Controller port board has broken down.
Can be easily replaced with a spare off an auction site.
