led tv vertical lines image
Don
I have a vertical line about 3 inches wide from top to bottom of my screen on the right side.... The tv pretty much works and anything inside of that line turns into a rainbow of colors... I read online it might be the buffer but I have no idea ... If u have any suggestions on what it might be or how to fix I would greatly appreciate it
Answer
LCD and LED tv screen are not repairable. If you do not have a factory warranty left for your tv, it would not be cost effective in repairing than just buying a new tv. Manufacturer does not repair them even if it was covered by the warranty, they would just replace the whole tv. Hope this will help you out.

what is the difference between brands of hd tvs that have the same specs but different prices?
also what is the difference and what is better plasma, led, lcd? Will the tv come with everything i need to get broadcast hd? What is 720 vs 1080?
Answer
Remember that just because they have the "same specs" they may not be the same. Example: one of two similar TVs may have double the number of inputs (HDMI; component-red, green and blue; composite-red, white and yellow...)
720 vs 1080:
720 stands for the 720 horizontal scan lines of display resolution (also known as 720 pixels of vertical resolution).
1080 stands for the 1,080 horizontal scan lines of display resolution (also known as 1080 pixels of vertical resolution).
The more horizontal lines on a display the more detail it can show = better resolution.
p vs i
Interlaced Scan - Interlacing divides the horizontal scan lines of display into odd and even lines and then alternately refreshes the display between all of the odd lines and then all of the even lines.
Progressive Scan - scans the entire picture line by line. In other words, captured images are not split into separate fields like in interlaced scanning they are "whole" images. Think of this as the same way the film in a movie projector works at the cinema. Progressive Scan is considered to be better than Interlaced Scan.
LCD:
The so-called "LED TV" is an LCD TV. The only difference is the backlighting technology - the actual LCD panels are exactly the same as other LCD televisions. Traditional LCD TVs use CCFL backlights (Cold Cathode Fluorescent Lamp) - think thin fluorescent tubes with a diffusing panel inside to spread the light evenly around the screen. Meanwhile, "LED TVs" (or to be more precise, LED-lit LCD TVs) use LED elements for the lighting source (think "Lite Brite" pegs, but all of them white).
PROS:
Reflections and glare are much less of an issue, good choice for brightly lighted rooms, no risk of burn-in of static images, use somewhat less power than plasma sets
CONS:
Lower viewing angle, lower ability to display the deepest blacks, the image can lose contrast, look washed out, or lose color accuracy as you angle away from the center of the screen, most LCD TVs can't display deepest black or distinguish subtle shades of gray and black, fast-moving images might blur, uneven backlight brightness has been an issue with LCD TVs, but the use of LED backlighting instead of fluorescent lights in some new sets potentially enables them to more evenly distribute light across the back of the panel for more consistent brightness on all parts of the screen, LEDs also use less energy than conventional lamps.
Plasma:
PROS:
It's hard to beat the best plasma TV sets for accurate colors, deep blacks, great contrast, virtually unlimited viewing angle, and fast motion won't blur.
CONS:
Plasma TVs are fairly heavy, reflections from a plasma TV's shiny screen, static images displayed for extended periods can burn in temporarily, and could become permanent if you consistently leave the same pattern onscreen over a long period. But that seems to have been more of a problem with earlier plasma TVs.
TV Inputs:
For connecting things like DVD players, Blu-ray Players, and gaming systems. List from best quality picture to the least.
HD Video:
HDMI - Does video and audio in one cable
DVI
Component - Red, Green, Blue
SD Video:
S-Video
Composite - Red, White, Yellow
Other things to consider when buying:
One of the most critical considerations with any TV is the number and type of inputs it has for hooking up devices to your TV. Also keep in mind where those connections are - front, side or rear- for quick hook ups. The connections a TV has is usually why two similar TVs can vary so much in price. Does the LCD TV have 120Hz or 240Hz technology - this helps to reduce the tendency to blur during scenes with fast motion, such as sports programs. Anti-glare screens - several plasma manufacturers are now offering screens with anti-glare surfaces, which can help reduce reflectivity off the screen's surface. If the sales person talks about contrast ratio - the higher the better - keep in mind that there a several ways to measure this and each manufacturer uses a different method, so it is really only good for comparing models for that manufacturer.
As for the TV coming with everything you need to get broadcast hd, that depends on what you mean by that. How do you want to receive your channels? Over-the-Air, cable, or Satellite? For over-the-air the TV would be good to go assuming you already have an antenna. Don't count on "rabbit ears" you are much better off with a roof top antenna. For cable or satellite you will likely need to get a set-top/converter box from your service provider to receive HD channels from them.
Last, and this is in my opinion, I feel that plasma TVs give you the best quality picture from a non-HD source. Remember not everything is broadcast in HD. This standard definition source it not going to look as good on an HDTV as it would on a SDTV.
