Our take on the LG 42LN5300

You can still find a few TVs in the 42"-43" size range with 720p screens, but when you consider that you'll probably be watching your new set every day for several years, it's worth paying a few dollars more to get 1080p. Why? Because most high-definition video sources are 1080-based. If your TV screen has a lower resolution than that, you won't be able to see all the picture details. The 42LN5300's 1080p screen delivers every bit of detail your best sources can dish out: Blu-ray player, game system, etc.

1080p is worth it

A screen calibration wizard helps you get the best picture

Too many people settle for a sub-par TV picture because the settings for contrast, color, etc. can be hard to find and/or tricky to use. LG's Picture Wizard II cuts through the confusion with easy-to-use adjustments and a quick self-calibration feature. The well-designed menu guides you through basic adjustments with "recommended" settings. For more precise adjustments, explore the "expert mode," which includes test patterns based on professional video calibration.

Great Deal From Crutchfield

Bruce from Huntington Beach, CA on 1/31/2016

Crutchfield Customer Review (What's this?)

I "needed" a set for the bedroom since my plasma was full of green strips. I did not want to spend a lot of money since I am saving for a "gee whiz" 4K. I am really happy with the set. I contacted Crutchfield by phone, got all my questions answered and bought it. I buy all my toys from Crutchfield and am totally happy with all aspects of doing business with them.

Pros: Clear picture, great controls

Cons: If it we in a den and we watched movies on it a sound bar would be a good upgrade.

Damaged Delivery

Charlie from Franklin Square, New York on 7/21/2014

Crutchfield Customer Review (What's this?)

This TV arrived at my home via UPS, the delivery man pointed out to me that the box was torn, but he said it probably was damaged by another box banging into it and it should be nothing to worry about. He left and I opened the box, the TV screen had been pushed in and was shattered, so very disappointing to me, I usually have no problem with UPS and their deliveries are usually great, I immediately called Crutchfield and their customer service Lady was very helpful and so sorry, she said although It may be too late in the day to ship this Friday, she would make a note to have it wrapped better for delivery Tuesday. It is not the end of the world but it is so disappointing when this could have been set up and running.



Happy with LG TV

Brenda from FLorida on 7/4/2014

Crutchfield Customer Review (What's this?)

This is a fantastic TV at a great price. I purchased it for my bedroom and it is more than I expected for such a good price.

Pros: Great Picture full of vibrant color!

Cons: Can't think of any.

The LG 42LN5300 meets our needs to a T

Feedvol from Takoma Park, MD on 6/22/2014

Crutchfield Customer Review (What's this?)

As an easy to use, LIGHT WEIGHT, 40" TV, this product is perfect. Our prior 40" screen, a 2007 Samsung, may have five times as heavy. Times have changed. Because we didn't require lots of jacks for associated equipment, this one is fine for our home.

Pros: Light, light, light weight. Very happy with 1080 dpi versus our prior 720. I didn't think I'd see the difference, but I do. Captures quick, live action sports w/o any perceptible lag.

Cons: Has the bare minimum of jacks. Other than hooking up two or three components, it's not set up for more than that.


LG 42 inch tv from Anderson , in on 6/1/2014

Crutchfield Customer Review (What's this?)

I received very prompt delivery and great service while ordering. When i received the TV its got a great picture and was very easy to hang in the wall.



LG 42LN5300

Mike from Ohio on 2/19/2014

Crutchfield Customer Review (What's this?)

Very happy. Easy set-up, beautiful picture. Speakers are o.k., comparable to other T.V.'s in the same price range. I run the audio thru my surround sound, so the speaker quality is not that big a deal. Excellent price and service from Crutchfield.




LG LED TV 42 Inch from 24293 on 2/11/2014

Crutchfield Customer Review (What's this?)

Great Delivery as expected

Pros: Great customer service. TV great. Great price.

Cons: None

LG 42LN5300

JH from Catonsville, MD on 12/11/2013

Crutchfield Customer Review (What's this?)

Arrived quickly, crisp picture, OK sound, easily set up. V lightweight. Fair price. 1st TV failed immediately (Samsung), but Crutchfield exchanged immediately for a better one.

Pros: VG picture on HD, sound acceptable.

Cons: Picture proportions sometimes slightly distorted, but Comcast feed faulty--a little slow on quick events like hockey. Probably works better with Verizon FIOS.

Nice television

Rob from Charlottesville, VA on 11/18/2013

Bought this to go in our bedroom. Picture is very good, set up was easy, price was right.



Good Value - Nice TV

ReidC from Mpls, MN on 9/8/2013

Crutchfield Customer Review (What's this?)

Very nice TV and an excellent value. It takes a little tweaking to get the screen just right but once you do, the picture is excellent. The 60mhz refresh rate is a non issue. Crutchfield shipped the TV quickly and it arrived undamaged (big plus) so the transaction itself deserves 5 stars. The sound is not that great which is common for these types of TVs, so that's the 1 star deduction. I'm going to add a sound bar rather than continuing to tinker with the settings. The slim design and small frame around the screen allow the TV to fit into a built in cabinet that previously housed a tube TV but this is a larger screen.

Pros: Excellent value, picture and purchase.

Cons: Sound quality is lacking but not a deal breaker.

Great Tv

Crutchfield Customer Review (What's this?)

very pleased with tv and crutchfield



excellent TV

tboneman from Boyne Falls, MI on 6/14/2013

Crutchfield Customer Review (What's this?)

This was our first HD TV at our summer home in Northern Michigan and it proved to be as good as any TV I have seen. The LED feature gives a superior picture. I was concerned with 60hz refresh rate would not be good enough for watching sports, however there is no jumping lag of a ball or puck across the screen. The price for a 42 inch screen was within our budget. Crutchfield delivered the TV and upon unpacking the screen was cracked. I called and they immediately sent a new one even before I sent the damaged one back. The second TV was perfect and arrived in only 2-3 days. Their service was quick, pleasant and without hassle. I'll use Crutchfield again as you can rely on their recommendations and service.

Pros: Great quality picture

Cons: None


Barbara from The Villages, Fl. on 6/10/2013

Crutchfield Customer Review (What's this?)

The 1st one we got kept going on and off so we had to send it back the 2nd one so far {1week old} now is working very well the best thing was this company they sent us a new one in 2 days, they were GREAT. The picture quality of this set is excellent.



Worth checking out!

John from Kansas on 5/22/2013

Crutchfield Customer Review (What's this?)

Got this as a graduation gift for my son and he loves it. He has been using it for Xbox, PS3, Wii, DirecTV and as a computer monitor. Everything looks great on it. It doesn't get hot like the 47" lcd in my bedroom which is very nice in the summer time when you are trying to cool the room. I was surprised how well this works as a computer monitor, I didn't expect it to be so clear as I have tried lcd's in the past and they don't display text very well. Installing the stand onto the tv was a little tricky and may be easier with 2 people. I thought I had screwed in the bottom piece fairly snug but when I stood the tv up it was wobbly and I needed to tighten the screws nearly a 1/4 inch more after the weight of the tv had pushed the stand deeper in I guess. I figure it was user error and overall I think this TV is a good deal. My son is happy with it and that's what counts to me.

Pros: Looks great when used as a computer monitor and we really like the audio outputs for connecting to a stereo receiver.

Cons: Screwing the stand on was a bit tricky for me but it had been a long day and I just needed to tighten the screws more.

Video Features

Direct-Lit LED Technology:  Direct-Lit LED backlight technology bridges the gap between lower-cost CCFL (fluorescent) LCD TVs and newer edge-lit LED-LCD TVs. LG's Direct-Lit LED-LCD televisions feature LEDs positioned all the way across the LCD panel's back plane (instead of along the side). Unlike "Full-Array" backlight LED-LCD televisions that also feature LEDs positioned along the LCD panel's back plane, the Direct-Lit LED technology uses fewer LEDs and do not offer local dimming. Since there are fewer LEDs, the LCD panel's back plane must be moved farther away from the screen to provide adequate light coverage across the LCD panel, making the TV much deeper than an edge-lit LED-LCD television. Direct-Lit LED backlight technology offers a better picture and is more energy efficient than previous CCFL (fluorescent) LCD televisions, though it requires a much larger cabinet design than newer edge-lit LED-LCD TVs.

Triple XD Engine w/ 1080P Resolution: The LED-LCD TV utilizes LG's exclusive Triple XD Engine video processing system for crisp images and rich, vibrant colors. The LG LED-LCD TV has a display resolution of 1920 x 1080 (1080p).

Video Inputs: The LG LED-LCD HDTV features HDMI, Component, and Composite video inputs. All of the television's video inputs are displayed at 1080p.

  • Dual HDMI Inputs: The two HDMI inputs will accept 1080p (60/24Hz), 1080i, 720p, and 480p video signals. The HDMI inputs not only allow you to connect your Blu-ray/DVD player or Satellite/Cable receiver to the TV, but also a laptop or computer.
  • Component/Composite Video: The one Component Video input will accept 1080p (60Hz), 1080i, 720p, 480p, and 480i signals. The component video input can also be used as a composite video input (480i only).

MHL Compatible: The HDMI 2 input is MHL compatible and designed for the connection of select mobile phones and other portable electronic devices. Simply plug your MHL compatible smartphone into the TV's HDMI 2 port using the HDMI cable that is included with your mobile phone. MHL allows you to display full 1080p video and still images on the LG TV from your mobile smartphone. The TV's IR remote can be used to control basic playback functions (such as Play/Pause, Stop Fast Forward/Rewind, and Menu navigation). Your MHL compliant device will also charge while connected to the TV's HDMI 2 port. To find MHL-certified devices, go to

HDTV Tuner: The TV has built-in over-the-air HDTV (ATSC) and Digital Cable (QAM) tuners, so you don't need a separate set-top box to receive and decode over-the-air HDTV/SDTV or unencrypted Digital Cable signals.

Picture Size (Aspect Ratio): You can select a different aspect ratio depending on input source (analog broadcasting, digital broadcasting, video input).

  • 16:9: Resizes the image ratio to fit a 16:9 screen.
  • Just Scan: Normally the edges of video signals are cropped 1-2%. Just Scan turns off this cropping and shows the complete video.
  • Set by Program: Depending on the input signal, screen aspect ratio changes to 4:3 or 16:9.
  • 4:3: Resizes the image ratio to fit a 4:3 screen.
  • Zoom: Choose Zoom when you want to view the picture without any alteration. However, the top and bottom portions of the picture will be cropped.
  • Cinema Zoom: Choose Cinema Zoom when you want to enlarge the picture in correct proportion. This enlarges an image with cinemascope aspect ratio (2.35:1) without distortion.

Picture Wizard II (Picture Control): This feature lets you adjust the picture quality of the original image. The LG TV's Picture Wizard II (Easy Picture Calibration) offers self-calibration with on-screen reference points for key picture quality elements such as black level, color, tint, sharpness and backlight levels. This feature takes the guesswork out of picture adjustments.

Picture Modes: The LG LED-LCD TV provides preset, user, and expert adjustment of the television's picture settings.

  • Presets: Easy to use factory presets for picture mode settings include:
    • Standard:  provides optimum viewing for general use
    • Vivid: maximizes the effect of the video by strengthening the contrast, brightness, color, and sharpness
    • Cinema: optimizes video for watching videos
    • Game: provides fast response speed for fast gaming system
    • Eco: this Energy Saver mode changes the TV's picture settings to reduce power consumption
  • User Adjustment: This mode allows you to adjust the video quality settings manually.
    • Backlight: adjusts the brightness of the backlight behind the LED-LCD screen; adjusting the back-light is recommended when setting the brightness of the TV; when decreasing the backlight, the brightness of the black becomes darker without any loss in video signal and the power consumption is reduced
    • Contrast: increase or decrease the gradient of the video signal; you may use Contrast when the bright part of the picture is saturated
    • Brightness: adjusts the base level of the signal in the picture; you may use Brightness when the dark part of the picture is saturated.
    • Sharpness: adjusts the level of crispness in the edges between the light and dark areas of the picture; the lower the level, the softer the image
    • Color: adjusts intensity of all colors
    • Tint: adjusts the balance between red and green levels
    • Color Temp: set to warm to enhance hotter colors such as red, or set to cool to enhance cooler colors such as blue
  • Expert Mode: The LG LED-LCD TV is ISFccc Ready and contains the detailed standards necessary for professional calibration of brightness, contrast, tint, sharpness, color levels and much more to meet local lighting conditions for both day and nighttime viewing. Settings are added to preset Expert 1/2 modes for easy access from your LG remote.

Advanced Picture Control: Advanced Picture Control allows you to adjust some of the advanced video features of the LG LED-LCD TV.

  • Dynamic Contrast: Adjusts the contrast to keep it at the best level according to the brightness of the screen. The picture is improved by making bright parts brighter and dark parts darker.
  • Dynamic Color: Adjusts screen colors so that they look livelier, richer and clearer. This feature enhances hue, saturation and luminance so that red, blue and green white look more vivid.
  • Preferred Color: Fine tune Skin, Sky, and Grass color independently.
  • Super Resolution: Provides a crystal-clear picture by improving the details in areas where the picture is blurry or unclear.
  • Gamma: You can adjust the brightness of dark areas and middle gray level areas of the picture.
  • Color Gamut: Maximizes the utilization of colors to increase color quality.
  • Edge Enhancer: Shows clearer and distinctive, yet natural edges of the video.
  • Color Filter: This function filters specific colors in the video. You can use the RGB filter to set color saturation and hue accurately.
  • Color Temperature: Adjusts the overall color of the screen by changing the white balance.
  • Color Management System: A tool that allows you to make adjustments by using test patterns; this does not affect other colors, but can be used to selectively adjust the 6 color areas (Red/Green/Blue/Cyan/Mgt/Yellow).

Picture Options: Additional picture options are available to enhance your viewing experience.

  • Real Cinema: Makes video clips recorded in a film look more natural by eliminating judder effect.
  • Black Level: Sets the black level of the screen to the proper level.
  • Noise Reduction: Reduces screen noise without compromising video quality.

Audio Features

Preset EQ + Tone Control: Sound Mode lets you enjoy the best sound without any special adjustment using factory presets. Standard, Music, Cinema, Sport, and Game are preset for optimum sound quality. You can also adjust the TV's Bass & Treble manually.

  • Virtual Surround: Virtual Surround delivers a simulated surround sound effect with just the TVs two speakers.
  • Clear Voice II: Clear Voice II enhances and amplifies the frequency range of the human voice to help keep dialogue audible when background noise swells.
  • Auto Volume: Auto Volume makes sure that the volume level remains consistent whether you are watching a commercial or a regular TV program. Because each broadcasting station has its own signal conditions, volume adjustment may be needed every time the channel is changed. This feature allows users to enjoy stable volume levels by making automatic adjustments for each program.

Digital Audio Output: The optical (toslink) digital output terminal will output Dolby Digital (when available) or 2 channel PCM. The digital optical output terminal only sends an audio signal in Dolby Digital when receiving Dolby Digital surround sound from a digital broadcast channel through the TV tuner or Dolby Digital content loaded onto USB. The optical digital audio output will only output in 2ch stereo from sources connected to the television via HDMI or RCA.

Convenience Features

This TV is programmed to memorize the caption/text mode which was last set when you turned the power off.

Parental Control: Parental Control can be used to block specific channels, ratings, and other viewing sources (external input block).

Q & A

Customer Q&A

1 question already asked

We have been happy with our LG 42LN5300, though, to be honest we have a low bar: we're going from a 19" analog. The only (slight) complaint is that the picture seems a little dark. Other than that, the clarity is not a problem at all -- might be your particular telly, and not the model. [ MITCHELL E  Jan 22, 2014 ]
I got rainbow looking on me screen when it turn white, across from one end to another. I called the LG company they didn't find closest place to repair, where I live in Alaska. It will cost to much to ship out and time. [ ROBERT J  Jan 22, 2014 ]
I have used a few of these for HD digital signage and had no issues with a blurry picture. It depends on your setup, give LG or Crutchfield tech support a call. HDMI to HDMI shouldn't have signal issues if you have a good cable . In some installations the cables get kinked. HDMI connectors are fragile. I have run into signal issues only on very long HDMI runs or kinked/damaged cables. Other than that, it is possible that you received a bad panel. Unlikely, but possible. [ KEVIN  Jan 22, 2014 ]
Hi. If you've followed all the proper steps in your setup menu (ESPECIALLY contrast) try hooking the same source component AND cable to the TV you like. Symptoms you've described could be caused by something as simple as a bad cable or a setting in your source. [ STEVEN F  Jan 22, 2014 ]
