lcd screen dark factory

Hi. It looks like the backlight on your LED TV has failed. LED TVs feature long thin circuit boards with surface-mount LEDs packaged every few inches. Direct backlit TVs have quite a few strips with the LEDS spaced out over the area of the LCD panel. Edge lit LED Tvs have the majority of the LEDs on the sides of the LCD panel. It looks like your TV is direct LED backlight.

The reason why Vizio told you to buy a new TV is because the LEDs which have failed are the hardest part to get to inside the TV. It requires you to disassemble the lcd display assembly, which is very fragile. In order to disassembly the display assembly, you need a lot of space and a lot of patience.

Also, even if you replace the LEDs or LED strips, it is extremely likely that your backlight will fail again within 2 years. A lot of the folks who repair LED TVs mention to go into the settings of your tv and manually turn the backlight of the LCD at least half way down. Lowering the backlight brightness will increase the lifespan of your backlight.

Verify if the surge protector or an extension is turned on in case a power cord is connected to these devices. If a TV screen appears black, plug another device into the socket to check whether this device is getting power from the outlet. If power is supplied to the outlet it means that your TV is powering on and a picture issue should be revised. You need to make a call to the TUSA Service Center and our technician will soon revive your TV.

There are many possible problems in case your TV is powered but a TV screen goes black and there is no sound. All you can do in this case at home is to reset your TV to the factory defaults. This procedure is described in the User Manual of your TV.

To double-check this failure press a MENU button installed on the TV to see if TV´s MENU appears on the screen, In case the MENU appears, verify that all video connections are well secured and to appropriate jacks on your TV. If the result is negative, you can trigger the MENU to reset your TV to the factory defaults.

Sometimes when watching TV, annoying situations arise when a TV screen fades off to black. That is to say, the TV screen goes black at random times and appears to be off but the sound is available and the power light is still illuminating. A troubleshooting procedure may differ for a variety of TV brands but generally will work the same to fix the problem and is as the following:

Connect a different device to the TV or the same device to another TV. The device being used (Ex. Blu-Ray/CABLE BOX) may cause the black screen issue.

A hidden fault within HDMI cable – Replace with new High-Speed HDMI 2.0 cable. Replace the HDMI cable as it may have a short or another defect which causes the black screen issue.

If your Vizio TV has seemingly displayed the black screen of death for no apparent reason, there"s a potential shining light in that dark, dark screen. Here are a few ways to fix the Vizio TV black screen of death.

If the problem you"re experiencing is a black screen because you can"t access a streaming service or internet app, it"s possible you just need to troubleshoot your Vizio TV"s Wi-Fi connection.

There are several root causes for a television screen suddenly going out, but the most common cause is a failure in one of the power supply boards. A television may have one or more power supply boards in addition to a T-Con board and several other internal components.

Some common issues that users have encountered with their Vizio TV include a blinking screen and not downloading apps. A blinking display could be caused by a bad cable or loose connection, and if apps won"t download, the first thing to try is power cycling the TV.

One of today’s modern technological wonders is the flat-panel liquid crystal display (LCD) screen, which is the key component we find inside televisions, computer monitors, smartphones, and an ever-proliferating range of gadgets that display information electronically.What most people don’t realize is how complex and sophisticated the manufacturing process is. The entire world’s supply is made within two time zones in East Asia. Unless, of course, the factory proposed by Foxconn for Wisconsin actually gets built.

Liquid crystal display (LCD) screens are manufactured by assembling a sandwich of two thin sheets of glass.On one of the sheets are transistor “cells” formed by first depositing a layer of indium tin oxide (ITO), an unusual metal alloy that you can actually see through.That’s how you can get electrical signals to the middle of a screen.Then you deposit a layer of silicon, followed by a process that builds millions of precisely shaped transistor parts.This patterning step is repeated to build up tiny little cells, one for each dot (known as a pixel) on the screen.Each step has to be precisely aligned to the previous one within a few microns.Remember, the average human hair is 40 microns in diameter.

For the sake of efficiency, you would like to make as many panels on a sheet as possible, within the practical limitations of how big a sheet you can handle at a time.The first modern LCD Fabs built in the early 1990s made sheets the size of a single notebook computer screen, and the size grew over time. A Gen 5 sheet, from around 2003, is 1100 x 1300 mm, while a Gen 10.5 sheet is 2940 x 3370 mm (9.6 x 11 ft).The sheets of glass are only 0.5 - 0.7 mm thick or sometimes even thinner, so as you can imagine they are extremely fragile and can really only be handled by robots.The Hefei Gen 10.5 fab is designed to produce the panels for either eight 65 inch or six 75 inch TVs on a single mother glass.If you wanted to make 110 inch TVs, you could make two of them at a time.

The fab is enormous, 1.3 km from one end to the other, divided into three large buildings connected by bridges.LCD fabs are multi-story affairs.The main equipment floor is sandwiched between a ground floor that is filled with chemical pipelines, power distribution, and air handling equipment, and a third floor that also has a lot of air handling and other mechanical equipment.The main equipment floor has to provide a very stable environment with no vibrations, so an LCD fab typically uses far more structural steel in its construction than a typical skyscraper.I visited a Gen 5 fab in Taiwan in 2003, and the plant manager there told me they used three times as much structural steel as Taipei 101, which was the world’s tallest building from 2004- 2010.Since the equipment floor is usually one or two stories up, there are large loading docks on the outside of the building.When they bring the manufacturing equipment in, they load it onto a platform and hoist it with a crane on the outside of the building.That’s one way to recognize an LCD fab from the outside – loading docks on high floors that just open to the outdoors.

LCD fabs have to maintain strict standards of cleanliness inside.Any dust particles in the air could cause defects in the finished displays – tiny dark spots or uneven intensities on your screen.That means the air is passed through elaborate filtration systems and pushed downwards from the ceiling constantly.Workers have to wear special clean room protective clothing and scrub before entering to minimize dust particles or other contamination.People are the largest source of particles, from shedding dead skin cells, dust from cosmetic powders, or smoke particles exhaled from the lungs of workers who smoke.Clean rooms are rated by the number of particles per cubic meter of air.A class 100 cleanroom has less than 100 particles less than 0.3 microns in diameter per cubic meter of air, Class 10 has less than 10 particles, and so on. Fab 9 has hundeds of thousands of square meters of Class 100 cleanroom, and many critical areas like photolithography are Class 10.In comparison, the air in Harvard Square in Cambridge, MA is roughly Class 8,000,000, and probably gets substantially worse when an MBTA bus passes through.

The Hefei Gen 10.5 is one of the most sophisticated manufacturing plants in the world.On opening day for the fab, BOE shipped panels to Sony, Samsung Electronics, LG Electronics, Vizio, and Haier.So if you have a new 65 or 75-inch TV, there is some chance the LCD panel came from here.

If your TV screen is black or you"re unable to get a signal when you try to set up or use your Chromecast device, try the troubleshooting steps below.

This article is intended to help with a blank screen, or no picture at all. If you are getting an error message on your screen, we"d recommend searching for the exact error message.

Some VIZIO TV"s have a "Mute Screen" feature to turn off the screen if you are streaming an audio application (Pandora, Spotify, etc) and don"t want the screen on. To activate/deactivate this feature, hold the mute button for 3-5 seconds.

If the model had attached with the power supply (AC-adapter), make sure the power supply has connected to the screen. Please check if the light of power supply is ON. If the light is NOT ON, change another power supply to test.

Are there any regional differences inpower specifications thatASUS LCD monitor supported (for example: If monitor was bought in Taiwan, can it be used in China or other countries?)

ASUS LCD monitor can support power specification: AC 100-240V. As long as within this voltage range, the display can work properly. However, please be noted that if you bought a monitor from another region, the power cord is not necessarily compatible to power outlet. Customer should replace the appropriate power cord or plug adapter in order to ensure normal power supply of the display.
