Question about Samsung UN55D7000LFXZA - 55in Led 3d Hdtv 1080p 240hz

1 Answer

SAMSUNG UN55D7000LFXZA with Striped all over the TV.

I had the for a couples of years and it just from nothing, appeared some stripes (vertical) and then it appeared all over. I turned the TV off for a couple of months and turned back again and came back to normal. After a 1 month using it, the stripes came back again. I would like to know was is going on and how can i fix it? I did opened the TV and it had two mother boards. One i think is the power supply and the other must be the main TV mother board. The solution could be replacing the main TV motherboard or is something with the actual screen? Thanks in advanced! Alf C.

Time to replace - TVs are throwaway items, replacing motherboards will cost you more than a new one in the end.
Get a new SMART Samsung with a five year warranty and replace when it goes wrong after the five years.
It's a new world out there.

SOURCE: Vertical hardly noticeable lines appearing on my samsung led tv

If you've cleaned the connexion between the motherboard and the display panel, I'm afraid the likely problem is the display panel.

If you have a friendly local repair shop, they might take a look at it and test with a replacement panel to diagnose the problem.

My al1916w monitor has a vertical blue stripe on the left side. It works fine except that the striped area discolors video. How do I fix that?


Unfortunately, a stripe on an LCD monitor indicates a physical failure of the LCD panel itself. The only solution is to replace the panel with a new one.

I have an 8 inch wide yellow vertical band in the picture of my 52 inch LCD Samsung TV, what is this? I just moved into my new house a couple of weeks ago and purchased a new 52 inch TV, We are without...


If the band is there within the menu then the screen has a fault. If not then possible signal ghosting issues and a proper aerial should fix that.

LG Flatron L1930B lcd monitor - 3 vert. stripes, center one dead


sounds like the pixel controllers have gone bad or one or more of the color (RGB, RED, GREEN, BLUE) controllers have gone out. this is quite common in lcd monitors/tvs and is usually caused by pressure on the edges of the screen (you grabbed it too tightly when moving the monitor) or just faulty controllers. they are expected to eventually go bad, ask LG for yourself, they will tell you the same thing. If you just bought it, that can be considered a mfr defect that they will replace, IF IT IS IN WARRANTY!!!!! Unfort. there is no fix due to seal that placed on the actual lcd panel inside the plastic casing. Youd spend more money trying to find the part and install it than just buying a new monitor. hate to say it but im an avid gamer and have gone through about 4 lcd monitors in tha past 3 years due to everyday use

Red-striped ghost images.


when you leave your TV (no matter what kind) and you leave it for long periods of time on a static image or something.. the image tends to burn in to the screen... so changing the glass would be a way to fix it.... the problem is that that kind of repairmen is more expensive and difficult than buying a new set...

The following can cause bands (vertical on a normal page)
