I had bought a PS2 about a month ago V9. I bought a Swap Disk with Card and was using it until I had enough practice on an old motherboard so I could chip my PS2. I was playing one of my backups when the PS2 turns off on me. It never turned on again. I think its the L2 chip. I knew that the chip would burn out if I used the backups without the romeo mod but I didn't think it would be so soon. I haven't opened the PS2 yet so I think I have warrenty. Do I have warrenty? Can I get it switched? I think I don't have store warrenty because its been more than 30 days. What should I do? Thanks.
