Have an HLS 5679wx/xaa. Brought it home few years back, had mainboard replaced first day, one year later, PS went bad. Samsung replaced it. This lasted 6 months, then I did the capacitor thing, has worked perfect since then. Except now, when i turn the channel the picture washes out. At first, I thought it was red only, but I have since seen red, green, and blue in the unusually lightened image. The colors show up more pink than red, the blue and greens are light in color as well. I can get it to work by power cycling it, but as soon as I change the channel, it washes out. Any ideas?
