Ok well I pulled up the tv menu screen and it still had the lines but they were actually behind the menu screen.

Well my WD-57732 gets little specs in the screen so we tried a new micro mirror and a whole new light engine but it didn't work. The TV will get 10 lines down the screen with the freckles and in about a week they will go away and the TV work like new and then a week after that it will start happenin...

Have you checked to make sure the fan is working properly?

Well my television was messed up for about 2 weeks and when I woke up this morning and turned it on it was working fine. I have no idea why it would do this but I'm just glad it works.

Ok I will have to look it up online to see which board the digital board is and once I get one I will let you know what happened.

some of them are part numbers like ,934C225001, but they all have something like for example, PWB-DM, also

ok I took the HD box from the living room into the bedroom where the TV is and hooked it up through the HDMI and it actually was worse than just being hooked up through a coax cable.

Any idea what the digital board may be called because I went into partstore.com and all the parts have like initials for them and I just don't know which one it is. By the way thank you for all your help.

I switched it from the cable input to the antenna input and it still had the lines but when I switched to the HDMI input it just showed a blue screen but I don't have anything hooked into the HDMI input.

I have a Mitsubishi WD-57732 and I have lines that are going down the screen. I bought a new optical engine but that did not help so wondering if the lamp can cause that or what the problem may be.
