Hello Gary, Thank you for the input... I just looked the schematic over for U8107 but I do not see it.. One problem is that I do not have the exact schematic for this model but Everything with this PTK-178L2 matches my information. I don't see a U8107 ..Do you know what this IC does or where this IC is located ? Thanks, Wayne... > > Wayne, I have a tip which says to CHECK R8158 AND U8107 for hourglass > picture. > > > ******* ATTENTION, PLEASE ******** > > I have a new email address.
