Its possible its just a bad connection like already mentioned. One good way to check for a bad connection is to run the set with a mirror so you can see the picture, and move all the boards around and push on the main board with a wood dowel. Don't put a lot of pressure, and don't over push on the plug in boards. If yer worried about a shock put a good leather glove on, use only one hand, put the other one in yer pocket. You should see the picture go back to normal when you move the parts closest to a possible bad plug, or bad solder joint. you can even tap, or hit stuff wit the wood dowel. Dowel should be pencil thickness, or a little larger, and about 20" long. I would not recap anything that will just cause you problems. Fix this problem first. Be sure its not a bad connection before you go on to replace parts. Sets with plug in boards - always check for bad connection plugs, contacts, solder joints first, its a known weak spot. Stay away from the high voltage section, you problem is most likely not there. Don't turn everything, a gremlin didn't turn all the turnie things over night to screw wit you.
