Question about Samsung HCN4226W 42" Rear Projection HDTV-Ready Television
I picked up this unit second hand unit. There are some bright magenta marks that are vertically aligned in the centre of the screen. They look like drops of liquid but this is only visible when the unit is on. Is this likely something that needs to be cleaned inside the unit?
These are burn marks on one of the picture tube, probably the green one from the looks of your picture (the absence of green will leave red and blue)This happens as the result of some kind of previous failure, hopefully that has been repaired now. However the marks will always remain unless you replace the green picture tube which is costly and which is why they sold the tv. Sorry about the bad news, if you decide to have somebody replace the tube for you make sure they look for what burn't it in the first place it could be intermittant and waiting to happen again to your nice new tube. Although seeing what model this is this tv did like to do this when the convergence failed in which case it looks like that has been repaired already. Good Luck, hope you didn't pay too much for the TV.
