Question about Samsung HLR5667W 56" Rear Projection HDTV

Open Question

Samsung DLP HLR5667W has blinking squares at startup

I have a Samsug 56 DLP HLR5667W that has recently displayed blinking green, red, yellow squares across the screen at an angle when I turn the tv ON (the picture is relatively clear and the color is good). This only occurs when I have the tv switched to antenna input - If I switch to the cable iput - I can't even see a picture, the screen displays (5) multi-colored vertical lines and a variety of wide/narrow horizontal bands. If I pull the 120 V plug on the tv for a reset - sometimes it comes back on clear with no issues and other times it doesn't. This only occurs when I turn the tv ON. If it starts that way - it stays in that mode

    I have the same problem the picture looks good until I turn on the Direct TV then it turns into an Irish plaid quilting pattern. You can still see a picture, but it is very hard to see. Picture frames are frozen and if you want to see the picture you have to turn on the PIP control screen to see it clearly. I used to be able to unplug and plug the TV back in and the problem would correct itself, but now that is not working either. I am thinking it has to do something with the filtering process on the TV from any cable/satilite hook up. I do not experience the problem until the satilite/dish is on. I have had this problem for about a year now.

SOURCE: 46" Samsung DLP Lines & Freeze up

This is a possible fault in the power supply, and can be a problem with some decoupler caps on some of the boards. The vertical bars and unstability are usually attributed to having high frequency noise and or clocking pulses crosstalking on to the power distribution lines that run through the boards. This can be switching power supply noise, or cross-talk from clocking pulses.

Another thing that can cause your described fault is unstable clocking between the devices that are reading and writing to the data busses. There are a number of data busses running through the set for the boards to be able to communicate with each other.

The tech will use the process of board swapping to service the set, and then do the adjustments as necessary to make sure the new boards match up.

Yes... DLP sets are fairly expensive to service!

This is my personal opinion. If the set is out of warranty, I would change for a Plasma or LCD set. If you compare the performance of these to ther DLP, the difference is very big. From what I am seeing from a service point of view, the DLP's are lower in reliability.

What you are sseing is a convergence problem within the light engine of the set. This is not repairable in teh field other than replacing the light engine part. Since this unit is less than one year old, it should be covered under warranty. From the looks of it, one of the LCD panels has shifted internally. Call for warranty service and indicate that the light engine has a problem. With luck, the service company will show up with the part in hand. Replacement should not take more than an hour or so.

There should be a jumper somewhere around the color wheel. I am having a problem with my color wheel, and after doing a lot of research I found that people that have the same problem as you changed the jumper setting. Try looking it up here on the net. Should solve your problem.

Black screen with a Blinking lamp in the front


Hi..if your lamp is on but no picture, then your lamp is good. Your problem is the DMD board (digital mirror display board) is bad. This is very common with Samsung DLP.

Distrorted Picture on all Analog Channels, HDMI and PIP Picture is fine.


Sounds like a bad DLP chip and they will prob end up replacing the light engine in the set most people dont like replacing this part. Hopefully they get you up and running.
