    Vizio M501D-A2R

    Having a convergence type issue.... when the screen jumps (tried to upload video, but issue has arisen.) there is blue and red image copies that outline the original image detail. Anyone seen anything like this? this is similar to what im experiencing on this set except its the entire screen, not any one section:

    Side tab Gate drive issue on that section of the panel. You can try cleaning and reseating the cables between T-CON board and the panel first, if that does not fix it then you may need to try taped -off method on the ribbon cables..

      hey, thanks budm. i also entertained the thought of it being a tab/cof issue as well. what gets me though is its the entire image across the display...not just a particular section. Is this still caused by one tab you think? also, it is not a constant issue....dont know if thats a difference or not, it pulses every 5 secs or so...fine, blue and red artifact image, fine, blue and red....yada yada

            Panel has failed. I am working on the same tv now and has the same problem. Interestingly, I put the screen in a 50" LG tv (LN series) to double check the double imaging and the results were the same. Vizio Tv is selling for parts
