I believe there may be a modification for that problem with the vertical IC and if I'm right Philips has a kit for it. I'll check the "Force" tomorrow and see. If it's there, I'll post it here. Phil@Phil's Electronics C.E.T. GNN3799 philselectronics@xxxxxxx www.philstv.com I had one of those and it was the vert output IC. I went through like 5 different ones from different places, and was about to just give up but I ordered an nte replacement, put it in, and it worked!!!! Could have knocked me over with a feather.
