Question about Samsung LN-R460D 46 in. LCD Television

Open Question

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.

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.

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

NFL52w4100 has a sluggish reaction on the left side of my tv and a darker picture on the right side of tv and will fix itself every so often and then go back to this picture

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Take it to a repair shop.

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.

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.

(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 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 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...............

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.

Dark shadow-like vertical streaks thru LCD screen (Sharp)

Hi, I have a Sony Grand Wega LCD Projection TV that has a blotted gray streak across the front of the screen. I only use a damp cloth to clean the window and that doesn't seem to help. It really shows up on light pictures and is unnoticed when the picture is a little darker. What can I do to fix this problem???
