Look close by the jungle IC for a small filter cap maybe Red or Brown or even Orange in colour should be abt 1mfd ..change it. kip -- "Watch the return E-Mail addy its false" "Jerry" wrote in message .. .

Hi John I appreciate your help but I still have a minor vertical problem. I
was just looking at the picture on the ToshibaTV , after replacing those caps (red 1 uf 50v) and (blue 0.47 uf 50v which was very close to the IC ) and I notice there is still a small 2 inch black raster on the top of the picture. When I first looked at the picture, I was just looking at the blue screen and it is perfect without video, I use to get the 1 inch black bar on the bottom and possibaly the top of the blue screen before I change the caps you mention, as soon as i put on a video the 1 inch black bar comes on to the top of the pic. I adjusted the vertical size pot and I got the picture to fit the whole screen , but there is still a very little noise on top of picture and when i go back to the blue screen the vertcal is oversized. I adjusted the pot off the factory red alignment markings, which I believe I shouldnt have to do if the vertical alignments are correct, Is there a Cap I might of miss or some other problems. Maybe the IC I was looking at is not the jungle IC, cause I notice there was another IC on a vetical board TA8615N, Do you have the Jungle IC # on hand?
