It sounds like the capacitors inside the DM board is going bad or there is a problem with the FMT or formatter board. The DM repair will require replacement of four capacitors and if not done right away, the problem will get worse and burn out the IC's inside the DM and the DM will cost about 1000 bucks to replace! Good luck

Lines across bottom of screen


are they blinking lines or just straight across from one side to the other blinking lines is the dlp chip going ( they cost a bit to replace)
no blinking then the mirror could of moved in the back of the tv, happens if the tv is not on level ground. or the dlp board needs adjustment ( happens over time as the plastic moves when hot to cold all the time)

You are probably seeing what looks like Jail Bars (Vertical Lines evenly spaced) on the screen. If so,then the DMD chip on the DMD board is bad and needs to be replaced

I have a 56" DLP Samsung (HLR5668W) Right side goes solid black


The color wheels will never fix an issue like that. The only things that will cause that issue is a bad DMD board which is part of the light engine or the digital board which is not. Freak Squad need to replace the digital board.
