I replaced the module sweep board in my zenith/bose tv# 9-367-07. The picture is clear and color good but it is distorted slightly like an hour glass. I am told this condition is called pushpin and there is supposed to be an adjustment. The picture was fine until I had to replace the sweep mod. I am inclined to belive that the new (used) mod set up for a different tv originally caused itand the adjustment might be there. Where is it and how do I adjust it? The tv is 1986 vintage. the tv shop said forget it, it is too old. Most parts are disco so I found my board on the internet.
