During the COVID-19 outbreak, we were chilling at home and watching TV. In the middle of a great episode of Say Yes to the Dress on TLC, the screen suddenly went black. After some time, vertical traces appear.
My first reaction was “wtf, be wrong” so surely changing channels and turning the TV off and on would help? It wasn’t.. What I found out is that the TV always responds to the remote and still has sound! Of course…let’s troubleshoot, the first step is to read the manual! Fortunately, we still have it, but if nothing else works, you can do a normal soft / hard reset with this. When I sent the TV to Sony and the provider I got the TV for any warranty, I went to Google to look for something useful. Some people with the same problem keep talking about some T-con boards. So I started a Google board T-con. I realized that there is nothing in a TV other than a screen and a few chips that control the screen. The T-con board seems to be responsible for displaying the pixels on the screen. Since the sound and TV are always responsive on the remote, it would actually be a dying chip.

In the meantime, I have received a response from Sony and the provider. Sony just asked for troubleshooting and the provider said they can’t do anything after the warranty expires. It would still be around 500 euros to buy one TV..But then it hit me…I’m an IT engineer! I can fix this myself! So I started taking the back cover off the TV.

I have screwdrivers, gloves and a good mental focus. I saw that the T-CON board should be under the main board. No problem, make this picture for me so I know which cable goes where. Find the T-CON board and check it with my eyes .. nothing special but ok .. will order a new one! Type in the code on the interwebz and find some sites that supply TV parts. Even located in the Netherlands…great!
A few days later I got the new T-CON board and put it inside the TV. Satisfied with everything, I turned on the TV to see if it was fixed. But nothing .. the TV always led to green and yellow beats. I turned the TV off and went back on Google and it says the TV is up to date and doesn’t seem to turn the TV off! After a few hours, he continued to beat them without any results. Finally, I read on the forum that you can update the firmware by downloading it from the Sony site, putting it on a USB-Stick and plugging it into the TV. Since the update might take a while, I did the same and went to sleep. The next morning I went to the TV and turned it on. The most beautiful light shined into my eyes and it worked! I was so happy! A new T-CON board was €50, so we saved over €400!
The lesson here is that even if you don’t know anything about something, with a little dedication, you can achieve “everything”!

How To Fix A Broken Led Tv For Free And Give It A Second Life
We forced the graphics department to draw a diagram of the anatomy of a liquid crystal display (this does not apply to AMOLED displays used in smaller devices):
An LCD screen consists of a backlight assembly, a matrix LCD display, and may include additional layers on the front for a glossy effect or diffuse reflection, and may also include a touch screen layer.
Just a few years ago, replacing a CCFL lamp was a convenient way to save money on fixing a 5-year-old dim LCD in some cases, but with the mass adoption of LED displays, traditional CCFL, modern. The LED backlight almost never fails.
This brings us to the most frequently damaged part of the laptop screen – the LCD matrix. At the core of the LCD matrix are two glass substrates that form a sealed container for the liquid crystal solution that forms the image. Each pixel is chemically printed on each of two glass planes, and each LCD pixel has three transistors called sub-pixels that become transparent (reorientable like window shades) when an electric current is applied. Light passes from the backlight through a sub-pixel in a color filter that displays one of three primary colors: Red, Green, or Blue. By mixing these intensities with these primary color combinations, each pixel can display 16.5 million colors individually.

The liquid crystal holding vessels are broken and the black spots in the ink that characterize a physically damaged LCD begin to scatter through the cracks and leak from the glass sub-states.
Unfortunately, even if the glass was re-glued with liquid crystal filling solution, thousands of transistors in the cell were irreparably broken (a 1080p display has 2,073,600 pixels and 6,220,800 subpixel transistors). – Stitching them together is like neurosurgery. Since there are very few connections that allow the LCD panel to work, fake or fake laptop screens are virtually non-existent. A state-of-the-art manufacturing facility with clean rooms and industrial filtration systems is required to make a modern working LCD.
Currently, some touch screens can be replaced separately from the LCD module – but they are also slowly becoming thinner and more advanced – some LCD modules already include touch screens in their structure – and in such cases, the touch screens can only be replaced together with the LCD. . .
