    My samsung dlp just started this flickering green screen problem. On all inputs. A ghost image of input can be seen through the green. The sound is fine. Also, when I display the menu screen it shows up clearly with all colors.

    I have a 50" Samsung DLP HDTV.  I purchased it in January of 2006, and just recently it started to flicker green.  This only happens on the cable input, not any auxiliary inputs, menus, or even picture in picture on cable have this problem.  The only solution i've found is to unplug it for a minute and then plug it back in.  It does come back occasionally though and is quite a pain.

    I have the same problem. Question, is the DM board replaceable? What is approximate cost? Thanks for all your help.

    I have the same problem. TV is only about 2 1/2 years old.

    I turned my TV on this morning and the green/flickering almost "rolling" screen was there. Yesterday it was 100% fine. The only thing I dont understand is that it's like this from the cable box into the tv and the DVD player into the tv but the secondary connection from the cable box works fine no matter which input i use...and the other two wont work no matter what input i use. Any suggestions?

    My problem is identical to "dwipman". I am curious if dipman got the problem fixed and if so, what was the final prognosis.

    I have the same problem. TV shows pictures like in the included pictures. I remove power then after a couple of attempts to turn it on, it works fine, both HD and standard channels.

  • darkmage_59 Jan 19, 2012

    Exact same problem as that first picture.
    It is over multiple inputs, so one could rule out it being loose connections, as well, while I am not 100% sure, it shouldn't be the color wheel. I have had a shattered color wheel before and this is not the same situation.
    I imagine it's just the board that is going to fail. Everyone says it. Samsung builds these piece of **** terribly so that they consistently fail.

    If anyone knows the solution, please post.

Just unplug and plug back in. Worked for me.

Try it a few times.

May not work for everyone.

Based on your general description, it could be:
1. loose connection or cold solder on any of the connectors and/or boards specially those related to power;
2. heat related - at some point, the heat generated inside the unit could cause a component failure or worsen a cold solder/loose connection;
3. a component is about to fail - on most Samsung projection TVs, this would be the DM board. Exhibited symptoms would be screen flickers (white flashes) and in some instances after about a minute the screen gradually turns very very bright (almost white) from the bottom of the screen to the top.

Any of the above would require familiarity with electronic circuitry and components, use of a DVM and a soldering iron as well as access to a service manual or at the very least a schematic diagram with voltage readings. Should you be uncomfortable venturing into a DIY, perhaps your best bet would be to seek the services of a qualified professional.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Samsung HLP5085W DLP - lamp replaced about 7 months ago. I powered up TV and got strange colors with flickering picture. Turned unit off and triangle symbol appears with lamp showing - needs replacement....

Strange colors and flickering picture symptom shows problem with color wheel and/or dmd board.
Lamp is only light source in dlp tv and it has nothing with colors or picture flicker.
TV goes to protection mode because of some internal problem as mentioned above.
If you wish to repair tv by yourself then you should have service manual copy in hand and that can be downloaded from HERE for small fee.
Hope these info will help you.

Samsung dlp projection tv-when turned on green horizontal lines show up acroos the screen

that is what was happening with mine.  Tech came out and we are not waiting for a new DMB board.  Glad it's under the extended warranty we bought in 2005 (which runs out next month) or it would have cost $500.00 parts and labor.

Rear Projection TV Picture is all green with Horizontal Lines

It looks like you started out with an intermittent solder connection which may have been fairly easy to find early on. Now, unless a technican can make it come and go while tapping on the circuit board and repair the connection, it may be a very expensive shop repair.
