After installing a HDTV cable box on in4 the tv went bad and I can not manually set the red converge,I have a triple image in the left and right side of the screen with cian,red and yellow colors.All input has the same problem.
I had the same problem and called comcast support, they told me to change the HD receiver settings from 1080i which is the default to 480P (not 480i) and the image shows up perfectly now. Also, The TV is by default set to 480p but using the service menu, you can change it to 1080i. i would advice keep the TV setting as it is and find out from your cable company how to change the output type from your HD receiver. Comcast Support was very helpful to resolve my issue.

The problem you have has nothing to do with the cable box installation! The convergence fault was going to happen anyway. Im sure you think the install had something to do with it? My freind, problems do arise with these electronic devices all the time , and just out of the blue. Sorry for your troubles ,BUT if your not a service tech or know the safety issues involved with the repair of tvs now a days, I would call a pro to assist you with servicing this set. As theres Hi voltage inside of sets even when they are unplugged. Good Luck
