Television

tbrace, your picture tube is getting a little tired, the "IK circuit" is causing the blanking of the video because the tube is not returning a large enough signal back to the IC that monitors it. Theres only one fix (besides replacing the tube) for your set and that is to turn up the screen control. You have to remove the back from the set and on the right hand side there is a large plastic part called a flyback transformer, with a heavy wire coming out of the top which goes up to the picture tube, mounted on the front of this transformer is 2 black blastic "philips type" controls, one over the other look closely and one will be marked focus(do not turn that one) and the other is the screen control, turn the set on and SLOWLY turn the control clockwise until you see a bright picture with white lines in it, once you see the lines turn it back until they disappear, (check several channels to be sure they are gone) your done, may last 3 weeks, may last a year, it`s all you can do, BMW Rider
