Is there anyway to get a Ntsc Pstwo working with pal TVs?

Hello,
I have a NTSC PsTwo(the slim one) modchipped when bought and a Pal television .I have used many kinds of ntsc - pal converters.most of them dont work and the ones which works makes light colors brighter .so its tough to play games. My friends told me that Ntsc-pal property depends upon a single wire in the Ps2 motherboard , changing it can make the ps2 into a Pal system. I have then googled about it and found out this wire changing stuff works.But no website has detailed info or help on it.It would be helpful if you can give me a link or give a detailed help on how to change this wire.
Thanx in Advance
