Question about Samsung Televison & Video

Open Question

I have a samsung LCD tv model LA46A550P1R model TYPE LA46A550P1RXSV and after 2years the screen on the bottom right started to show a different colors when the TV is left on for some time. Recently the problem has spread to the entire right half of the screen and every so often the picture starts to flicker uncontrollable on this side of the screen. I have maintained the set extensively and have been using a voltage stabiliser ever since

SOURCE: Picture Flickers Briefly Shortly After Power on

If the set is only a few weeks old you should put a claim for a warranty repair or exchange I believe is the back light(lamp)doing the flickering and should not be doing that at all and it will not go away by itself,it might get worst. Let Us know how it goes or if you need more information.

SOURCE: Blue color spread over the pictures

This sounds classic to a thermo problem where a part(s) are becoming thermo sensitive with aga and use. When the set is cold and then warmed up, the defective part(s) is changing characteristics.

Some components became thermo sensitive that are driving the display. Or an embeded component in the display itself became thermo sensitive. It is very possible that the fault is on the board that does the X - Y addressing or on the backplane electronics of the display screen itself.

Using the set with defective components is a bad idea. If the part(s) fail completely and go shorted or opened, other more costly damage can be done.

The service rep for the manufacture of your set is equiped and trained to be able to troubleshoot and service your set.

You will have to take the set in to have it serviced.

SOURCE: Vertical colored lines on left half of screen.

I had this problem on a 37" Viewsonic LCD. Pulled it apart and through a process of elimination, I traced the problem back to a small board with several flat white ribbon cables coming out of it. The board was near the top center of the screen and under a ton of other equipment requiring almost a total disassembly.

This small board was clean but I noticed one of the rubber standoffs had slipped down and was making contact with one of the outputs running to the LCD. It also happened to be the output running to the section of the screen with the problem.

I postulated that the sticky glue on the rubber standoff may have just enough conductivity to cause a problem. Moved it so that it was no longer touching anything electrical and then reassembled the TV.

Afterwards, I turned it on and was pleased to see the problem has gone away! If you're having the vertical line problem, then maybe this could be your problem too, especially if you have a Viewsonic since it could be a manufacturing defect.

WHAT IS WRONG WITH MY SAMSUNG LCD, MODEL LN46A550P3F. THE FAR RIGHT SIDE OF THE SCREEN IS DISCOLORED (ABOUT 1/8 OF THE SCREEN, TOP TO BOTTOM)? AND HOW DO I FIX IT?


Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should be troubles hooted. Contact any service technician. The circuit will differ with models and versions.

My led samsung tv has a horizontal line and the upper right corner shows a white vertical lines


Not good. You may have a tab failure. A repair shop may be able to diagnose and repair this, but most likely the lcd panel is broken. The panel is the most expensive part of flat tv's. A new panel will cost more than a used tv.
