Samsung DLP model HLR5067W has three horizontal green grid-like boxes
Please help. Our Samsung DLP T.V. has three horizontal green rectangles that look like grids going across the screen. They're about three inches high and six inches long. I'm on eternal hold with Samsung right now and getting more frustrated by the minute. Do you know what our problem could be? I can't find this issue in the troubleshooting guide in my Samsung Manual.

I looked up how to fix red horizontal lines on a Philips flat-screen tv. It turns out it needed the Y buffer upper replaced. I am not sure if this problem would be similar but it might help. I am also searching how to fix a fuzzy screen on a DLP tv. Hope you find what you need.
I do suspect the digital board with the part number of BP96-02084A. You shouldn't have to replace anything but the digital board for a freezing issue. Whn these boards are changed the settings need to be written from the board manually or electronically saved to what they call the DMD board in the TV. If not the possibility of the color looking wrong is great once its replaced.
Not too familiar with this exact model but am very familiar with Samsung DLP. If this is a Rear Projection (3 CRT's R.G.B.) it is surely the convergence chips ($12 each X 3). If this is a DLP (Color Wheel @ 7000rpm) this is not good news as a DMD board for Samsung DLP is around $400 (not retail either, warranty part price).
I hate to be the bearer of bad news, but it is not something that has a quick fix. Without inspecting it myself it is impossible to say, but the last three of these that I have seen have been bad digital boards and can be a real bear to change, even when you have experience.
I would get slightly different video symptoms when I would switch between the coaxial input to the component input to the HDMI input. But in all cases my on screen display and menu were anomally free. Hope this was helpful, even though I don't think it is something you should attack yourself.
