Question about Samsung LN-R460D 46 in. LCD Television

1 Answer

One side of the screen is darker than the other...

Greetings! My dream LCD tv is less than a year old and the image has already malfunctioned. The image is darker on one side of the the television. There does not appear to be any 'burned out' pixels, but the illumination is off balance. It has been in a "authorized Samsung repair shop" for over a month, and I am told the entire panel needs to be replaced, and they are waiting for this to arrive from Japan. What is exactly wrong with this television? The repairman cannot give me a direct 'technical' answer, and I think he does not even know the problem... Any advice will be greatly appreciated.

Back - light problem. 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.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board

SOURCE: CRACK LCD TV SCREEN

I had one broken a few months ago. I got a couple quotes.. it was about $200 less then a brand new one. I'd just buy a new one.
For the new TV I'd pickup a screen protector for it. My son threw a toy at my TV the other day and I nearly had a heart attack from the flashbacks. Thank God I picked up one of these a few weeks earlier. It stopped it. LCD screens really break easily as you know. http://www.tv-armor.com

SOURCE: LCD TV SCREEN PROBLEM RED HORIZONTAL LINES OF DOTS ALL OVER SCREEN PLEASE HELP

This should be repairable. It may be the LVDS Cable or the Main board problem. The only other problem is the T-Con Board.

SOURCE: Samsung 46" LCD LN46B650 started showing vertical

had a very similar situation with my Phillips 42 in. LCD TV.

Here was my Problem. The Power Supply Board. I opened it up( Warranty was Expired) and found several faulty capacitors on the PSB. Its pretty common. Major Electronic companies were sold faulty capacitors that fail in 2-5 years instead of 10-20 due to a lack of preservatives. It wouldn't surprise me if you have the same problem. TV will work fine for a few years and then just fail completely or slowly deteriorate.

Here are the solutions
1. Have it Repaired
2. Check for faulty caps and if you find some(budged or leaking) you know you have located a problem
Remove the board and replace the whole thing.
3. If you have some soldering skills you can replace the faulty caps.
Caps are very inexpensive, under a dollar in most cases. I replaced 4 for about $5.00

Hope this Helps.
Good Luck

Plasma -vs- LCD? Pros and Cons


If you're looking into a new TV purchase these days, you have only a few options… Plasma and LCD are major hitters. What follows is this professional’s opinion; you must ultimately do the research yourself.


Plasma TVs
Pros: Exceptional color reproduction. Our eyes have become accustom to viewing TVs with Phosphorus displays. As with TVs of old, Plasma TVs also use Phosphorus to create the beautiful colors our eyes crave. The viewing angle (side to side) and refresh rate (rate at which the image is refreshed) of a Plasma product shines above most other product types. Plasma TVs also have a glass protection screen in front of the panel which can help protect the panel from impact. Prices have fallen recently and have made the Plasma TV a very affordable purchase.

Cons: Energy usage. Using a Plasma TV has been likened to 'leaving the refrigerator door open'. Reliability and longevity are also a factor to consider. Over time, the Plasma panel becomes more sensitive; “Sparkles” or misfiring pixels are common. The Plasma uses many high power components; which, due to failure, have given it a less than reliable stigma. Image retention and image burn are quick to occur. Realistically, 5-7 years of life.


LCD TVs
Pros: Light weight and bright picture. Color reproduction has improved by leaps and bounds over the recent years. Some products available do rival the Plasma products in picture quality and reproduction. Cost cuts have also brought the LCD into the price range of many. Energy usage is typically less than that of the Plasma. Image retention is not a major concern for this product. Less parts than a Plasma = Less failure. LCD panel life is estimated to be about 10 years.

Cons: LCD panels use back-lighting systems. Because the 'color' of the light does not change, the color reproduction of the LCD product is not as natural to the eye as the Plasma product.


LCD-LED TVs
(Same as LCD TV, with the following exceptions)
Pros: LED back-lighting produces a more Plasma like color response.

Cons: Panel life is about 70% that of the standard LCD products.

My LG TV has suddenly become darker all across the bottom of the screen (10cm strip) it still has colour but is darker. In left hand corner it is considerably darker and depending on what you are watching...


Hi; your TV has burn screen or traces.it comes from one image left on the screen for too long, it can get burned into the screen, making it visible at all times. You can actually eliminate most screen burns with the use of a PC computer and a black and white screen saver. This trick eliminates screen burn after a period of several minutes because the black and white screens flash quickly, removing all traces of color from the screen. This will eventually eliminate any burned images on the LCD screen. you can do it by creating a DVD picture slide with only black and white image. you can use a computer to make DVD picture slide first go to paint brush and draw only white then save as white.jpg. second burn it into nero or other dvd burner third play it to your DVD player connected to you LCD TV.it has to be played in full screen let the white image display on your HDTV for several hours or even overnight. It should remove any burned-in images or ghosts. hope this help...............
thanks....

Diana, did you ever find a solution? My Toshiba (same model) is about 2 years old and it started getting these 4 horizontal lines spaced pretty far apart and a double image at bottom. When I lightly tap the top of the TV, they went away. But now that is not working. Please let me know. Thanks.

Right side panel of my Philips TV is flickering


You need to replace a capacitor in the 'Horizontal' IC sectiom. If you are not a TV tech with excellent soldering skills and the correct testing equipment, I suggest you have a repair shop do it for you.
