I will go check the DC voltages on the IC but first i did what the Sam"s said to do and that is scope PIN 13 of the IC. i got a new oscilloscope but i never took it out of the box as was going to be moving soon but i finally broke down and took it out of the box and tried it out. The results are in the video link and i have never used an oscilloscope before so the results may not be usable.
The video is not of the best quality but its best me and my grandma could do and my phone camera is not very good.
