SOURCE: no picture on samsung lcd tv

I have the same problem. I brought a Samsung 46" in July 07 and on Jan 8, 2008, video went blue.

I called Samsung and sent out technician and they replaced the motherboard.

Two hours later, same problem occured. I called today and Electronic Company thinks I have a bad LCD panel.

SOURCE: Samsung HLS 5679W LED DLP TV Horizontal white lines jagged across screen.

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.

I just hooked up my new Samsung 55" LED LCD TV it has 1920 X 1080 resolution and 240Hz speed. Initially the picture quality was fantastic, sharp clear great colors...almost jumped off the screen at you....


Try the Direct TV connected to the TV via component cables and see if the picture is clear and stable at the same time. If it is normal check the Samsung website for support on your model of TV to see if there are ANY known issues and or software updates. Please take a moment to rate my answer. Thanks..

Most likely cause:
Backplane lamps, and or the backplane power supply is defective.

I don't know the particular model, but in most of these models, these parts are replacable. I suggest giving out the set to a tech who is experieced at doing this type of work. The parts would have to be ordered from the manufacture.

Jumpy picture


If this set uses a picture tube then your problem may be in the vertical deflection circuit. Also an unstable power supply will cause this problem. Stargazer
