    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.

TH-42PX75U horizontal lines (flickering black and white)

The controller board for the screen is going bad. check for replacement parts. It's not a difficult job to do. Once the back of the TV is removed, you'll see it near the center of the screen.

Is it hooked up with HDMI cable?

If so try unplugging the HDMI cable and re plugging the cable in, sometimes those cables work loose and if they are not tight, it will cause your screen to flicker. Happens to my TV once in awhile.

You can try adjusting the green screen control but you need anew CRT ( tube) the speaker cover has two plastic plugs that get removed on the lower edge os the grille which covers the two screws that hold the grille on. If you need more assistancr or where to get a green CRT let me know as I have a link that has some green and red Tubes for your model.
