Hitachi CT7872B - picture v-roll
|
Can't Post

|
Hi, I have an older Hitachi TV 1991 generation. The picture has just started to roll on both cable, vcr, and direct dvd imput via the seperate composite video input. The vertical hold adjustment on the front of the TV does not stop the rolling. Is there and additional pot adjustment on the control motherboard. I have found the vertical size adjustment pot but not the vertical hold pot. Missing a schematic. Please let me know if you have any suggestions. Thanks, Dale
