I have been a user of Sanyo tvs for a long time but now I find that there seems to be a problem with the horizontal parts of Sanyo tvs. I have had trouble with three Sanyo TVs, first a 27", next a 36" and now my 21". On all three the horizontal has gone bad. At this moment I have 4 Sanyo TVs in my home. It appears that maybe you have a problem with the parts you are using in you TVs. I know that as of now I will not buy another Sanyo model TV, I can't afford to go out every 3 to 5 years and buy another because the horizontal hold has gone bad.
