Vizio Model M420KD picture seemed a little fuzzy for a few days. That was about 5-6 ago. Then suddenly a green out line around people and faces, now it has a thin white vertical line through the left side of screen and heavy green ghosting on the whole picture. Tried to reset picture settings but that made it worse. The sound is fine, just the picture is green and distorted.
If you've ruled out that the source you're displaying from is good, I would contact vizio for a warranty repair
SOURCE: No picture/vertical lines on screen
it's called retrace lines ,your screens are set to high or focus block assy which has the screen adjustments on it also is faulty
SOURCE: Sudden discoloration, ghosting, bowed horizontal lines in top and bottom of picture
Everybody here seems to have basically the same problem so I will write a general fix for these Samsungs. First what you got is known as Convergence failure, A Ic or resistor, fuse or some other component has failed in the convergence circuit. So finding the service menu and trying to align the colors or spinning magnets on the CRT’s or a real bad idea of tipping a CRT or mirror would be the equitant of ripping the transmission out of your car because it had a flat tire. When the convergence fails no adjustment will bring it back, and if you do one of these stupid things then you have two problems. Now most of these Samsungs have an easily replicable board that all the convergence amplifiers are on. This can be found by removing the back and seeing if there is a board about 9 X 5 inches big and mounted to the CRT mounts, there will be 5 connector to this board. Now if your set does not have this board and instead has the two convergence Ic’s (these are about the size of a playing card and have the numbers STK392-040 on them) mount down on a board below and to the right ( this is known as the deflection board) this repair will not work for you. Instead you will need to component level repair the convergence circuit. But if you do have this separate convergence board the repair is fairly straight forward. Go to www.vancebaldwin.com or some other supplier and order BP95-00142E this is the convergence board. This board has been crossed several times through the years but this is the current version. Now once you get this board simply replace it making sure to get al the connector back in there original spot. The fire up the set and run Flash focus and for about 95% this will fix the set

I suggest unplugging your entire system for one minute to try a reset again. Sometimes a system reset doesn't take the first time. If this does no good you probably have damage to your digital board or dmd board. I have a smaller version of the same set at home and have done samsung's warranty service for several years. They deliver a great picture but do need regular maintenance and or repairs. The upside of all this is if you have homeowners insurance it may be covered, depending on your deductable amount. However, a dmd board can cost 500.00 so you may have to go that route. Hope this helps, Russmann.

This is caused by a capacitor on the power board going out. The unit is under warranty, but because it is under 30 inches, will have to be mailed back to California. They will replace 2 boards for you: The main board and the Power PCB. This will fix you good as new.
