I currently have a Toshiba model 27A41 that has a very intermittent video distortion that is rather hard to describe and unfortunately my digital camera is at a different location. I will attempt to get it so I can hopefully get a good picture of it and post it to my website later because we all know a picture paints a thousand words in a case like this. I have ONLY noticed this symptom on the RF input but have not yet determined if it occurs using any of the video inputs (composite, component, or S-Video). I am now running a DVD using composite video to see if it does occur there. The best way I can describe the symptom is that first I do not notice any audio problem at all, only the video (or raster) is affected. The picture will get these vertical distortion lines like it is breaking up (no loss of sync though) and at that time when this occurs, there are bands of purity distortion that accompany the distortion. It can occur from a dead cold start within a minute or the set can run for hours and then act up. I have been all over the board with jewlers goggles and a jewelers loupe and can find no cracks or bad solder. I cannot induce the symptom by tapping the board nor by freezing or heating it. The symptom is completely random. So far I have replaced the following components yet the symptom remains:
