I did check the vcc pin on the chip 11.4v and all other voltages seem to be fine. which what the schematic says. However I found problem I created in the tuner I forgot to resolder a capacitor lead while I was testing the caps. The replacement chip was a defective as picture had a lot of noise but it worked otherwise. That's how it behaved in set I pulled it of before I scrapped that TV. So I put the original chip back and much better still has the same problem as it did in video one but at least the picture is clear and the AGC set at the factory gives the best picture. I'm thinking something wrong in the sync maybe?
