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!

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.

Samsung DLP vertical black lines

I did some reading on this. They said its caused by a faulty DMD board. I understand it's costly... around $700 to replace. Still looking for a cheaper avenue...

I had black vertical Lines. Sometimes across the entire image, sometimes partial. Came and went. Seems a dead-ringer for cold solder joints on the BGA of the DLP IC. 
So i threw down $15 and bought the service manual online, pulled out the entire light engine assembly, and blew everything out, vacuumed etc. 
I then tightened the heat sink on the DMD (supporting the DLP chip). Made the problem consistent (black lines) always. So then I slightly loosened the spring clamp screws - black lines went away.. Obviously this varies from each device, where the cold solder joint(s) are etc, But this will keep the Mrs happy until I work up the courage to reflow oven the DMD board, or get a new one. Anyone reflow oven their DMD boards yet?

Nope, nope and nope... It's likely the DMD board and unless you have some SMT (surface mount technology) equipment just laying around you're not repairing that board too easily... You could however remove it and send it in to PTS for rebuild at about half the cost of a new replacement..
