Question about Samsung LN52A850 52 in. LCD HDTV

1 Answer

Green and purple scrolling lines

I have an LG22LC2D-UB that was purchased installed in January 2008.  Yesterday, we installed a ground in that circuit and the scrolling purple and green lines started today.  We watched a movie on On Demand after watching some other shows which is when the lines started.  We are in the process of switching the tv and cable over to an outlet that was not grounded as I type but I don't think it will work.  I have the Best Buy service plan, should I bring the tv in or at least have the geek squad come inspect the tv? samsung 52" lcd tv but i have green and purple scrolling lines only when the cable is on. when theres a dvd its perfect. i dont know wheather to get a cable tech or a tv tech?

SOURCE: Pink and green lines while watching a movie

if this is only happening on your dvd player, then change the type of cable used to link the tv with the dvd player, if that does not fix it then try another dvd player to make sure it's not the player itself

SOURCE: 52" Samsung that the top half of screen goes black.

the HDTV has a heat-related problem check your fans. Do they remove heat? the vertical chips paint the screen from top to middle and, middle to bottom so; your top to middle vertical chip is overheating as is your video chip; that is why you have "glitter" in the back ground. get rid of the heat or, bye,bye TV.

Green and purple horizontal lines

You will most likely need what is called a scan converter/scaler. It will convert your source signal to the desired signal for you. You can find these online.

I have green or purple or dark lines scrolling up the screen on my Sanyo 42 inch plasma TV

These lines are often caused by interference. Try putting a filter on the input power plug. Make sure there is nothing near by that can be causing interference, like another monitor or computer, microwave oven, fluorescent light, etc. Make sure all the antenna leads are tight and the converter box well grounded. Is this dish or cable?

I have a Hampton Bay, Glendale 52 inch ceiling fan/light. I've installed ceiling fans in the past and am used to having 4 wires coming out of the unit - black, blue, white and green. There are black,...

green on the fan is for grounding the device, some have only a braided bare cooper line. grounding is a safety essential and all modern UL tested electrical devices will have some means of grounding to the homes grounding circuit (the bare copper line). check the installation instructions for the proper grounding method. Then you might consider having a qualified electrician install your fans.

Pink and green diagonal lines rollng across the screen??? panasonic 42" Plasma . Only purchased about 3 years ago - but been used very rarely.

Have you tried lifting the ground on the TV? That set has a grounded (3-prong) plug and sometimes sccrolling lines can be caused by a ground loop in your power lines.Are the green and purple lines very short, like just a few rows of pixels tall, or multiple inches, like 3 - 8 tall?

I need a wiring diagram for my DEH-6000 ub stereo

red - ignition, 12 volts with key turned on

yellow - back-up, 12 volts all the time, even with key off

black - ground

orange - illumination

blue - power antenna or remote turn on for external amplifier

grey - Solid grey is postive front right speaker, grey w/black stripe negative front right speaker

white - solid white is positive front left speaker, white w/ black stripe is negative front left speaker

purple - solid purple is postive rear right speaker, purple w/black stripe is negative rear right speaker

green - solid green is positive rear left speaker, green w/black stripe is negative rear left speaker

You may also have a wire for "mute" which mutes the speakers when you have a phone call or other accessory connected to it. I can not remember off the top of my head what color it is, but most times it is brown. If you have an extra wire I have not listed, that will most likely be the one. Most people never use this wire.

I hope this helps, and if so a FixYa! rating would be appropriate and very much appreciated, after all, it is the only reward we get for helping people like yourself for free.

I would be happy to offer more help if you need it, just reply to the post and I will get back to you as soon as I am able.

Good luck with the installation of your radio,

Purple and green scrolling lines

This may be a mechanical or electronic problem that is dealing with the sync of the colour wheel. There is basicly no colour lock. This may be the replacement of the associated circuit board, or the motor assembly or the colour wheel.

The link below is describing about how DLP technology works. They are relating to a front projection type. With the rear screen type, the basic technology is very much the same for decoding the pictures from the TV signal.

Scrolling Line Propblem

You have a ground loop problem. Buy an adapter that lifts the round ground prong and poof, clean picture.
P.S. Or fix the grounding. More than likely two different ground potentials between Cable/Sat and house ground.
