On & Off

[Dirtydriz]

I installed the Matrix Infinity in a version 5 and when I turn on the power then push the on button it turns on for about 2 seconds then goes back to stand-by. I have checked every connection with a volt meter and every connection next to my solder points to check 4 bridging and the are pretty good so could it be a bad pad or joint? First time installing on the ps2. Then did my v9 and it works great.any thoughs would help!!!!
