Question about Samsung HLP4663W 46" Rear Projection HDTV

1 Answer

10 sets of 8 vertical lines

We have the same problem.  Is your tv still working fine since you replaced the DMD board?  How much did that part cost, or how much do you think it will cost to repair?  We'd rather repair the TV than buy a new one as we really love the picture. Thanks.

Yes, my TV is working just great since I replaced the board,

I can't tell you much about the cost of having somebody else do it. When I first started this a Sears tech gave me a price of $1500 to replace the entire projection unit, which was ridiculous enough to cause me to attempt a DYI solution.

If you are moderately handy, you can order one from and install it yourself. They are selling them for a little over $500 with a $50 core charge. (I'm pretty sure these are refurbished modules, because they were charging in excess of $900 last year).

The replacement is pretty easy, but aligning the board can be a tad tricky. It's no catastrophe if it isn't perfect, but it's nice if it's done well.

You can e-mail me at if you opt to attempt this, and I can give you a few specific tips when the time comes.

Good luck!

Hi, can you tell me what you see on the screen? It could be a bad cable. Are you using an HDMI cable or the color cables (RCA cables)?

Mitsubishi tv has white vertical lines on screen after replacing part 1910-6103w

You either got a defective DMD chip or the problem moved to your light engine or main board as well. To find out if it is light engine side or main board side you will check like this.

Turn off TV. If the line go away when the picture goes out, then the problem is on your main board. If the lines stay for a second or 2 after the picture goes out, the either your engine is bad, or you received a defective DMD chip.

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

Samsung 56 HLR566 Vertical Green Lines

I suggest unplugging your entire system for one minute to try a reset again. Sometimes a system reset doesn't take the first time. If this does no good you probably have damage to your digital board or dmd board. I have a smaller version of the same set at home and have done samsung's warranty service for several years. They deliver a great picture but do need regular maintenance and or repairs. The upside of all this is if you have homeowners insurance it may be covered, depending on your deductable amount. However, a dmd board can cost 500.00 so you may have to go that route. Hope this helps, Russmann.
