What Does A T Con Board Do?

“Welcome to our post on the T Con forum! In this section, we will explain the purpose of the T Con board in a simple manner. So, What Does A T Con Board Do? Let’s dive in!”

What Does A T Con Board Do?

The T-Con board, also known as the timing controller board or control board, is a crucial component found in all LCD TVs. Panel Repair Factory is a leading supplier of T-Con boards to LCD TV manufacturers and repair agencies worldwide. The T-Con board plays a vital role in controlling gate signals and driving the TFT-LCD panel effectively. It incorporates a frame rate converter with a range of 60 to 120 hertz.

The T-Con board manufactured by Panel Repair Factory is designed to generate accurate voltages based on the specific panel used in the LCD TV. It operates by receiving voltage from the motherboard and consists of specialized drivers, high-quality circuits, Gamma correction, and high signal input. This combination enables it to deliver clear and precise color reproduction on the LCD TV screen.

With the inclusion of a special field-programmable gate array (FPGA), the T-Con board ensures stable and reliable performance. Advanced interpolation algorithms employed in this board guarantee excellent font and image display, perfectly synchronized with each other. Additionally, it features a robust power protection mechanism that safeguards the device from electric short circuits and damage caused by excessive heat.

What are the symptoms of Samsung T-Con board failure?

Step 1: Troubleshooting T-Con Board Issues

If you are experiencing certain issues with your Samsung LED TV LE37A659 (or similar models) such as moire patterns, “negative image” colors, low-contrast colors turning white or dark over time, or image distortion, the problem might be with the T-Con board. Follow the steps below to check it:

Step 2: Opening the Back Cover

1. Before starting, make sure to unplug the TV.
2. Be cautious as the circuit board contains capacitors that can give an electric shock if discharged. Avoid touching them while working. If possible, use a capacitor discharge probe to safely discharge the capacitors.
3. Place the TV on a large, flat surface with the display facing down.
4. Loosen all the screws holding the back cover, except for one that is marked with an orange arrow in the picture. Pay attention to the four screws in the lower center region as they hold the stand (the base).
5. Remove the back cover gently without applying force. You can collect the screws in a box or leave them sticking in the back cover to keep track of them.

Step 3: Removing the T-Con Board

1. This picture shows the TV’s interior with the top facing you (bottom side of the picture). The power supply board is in the center, and the main board is visible. The T-Con board is hidden by a metal cover.
2. To access the T-Con board, remove all screws on the parts that cover it. The screws are marked with an arrow symbol.
3. Loosen the two screws to remove the wall mount bar.
4. Remove the metal part on top that blocks access to the T-Con board.
5. Disconnect the connectors attached to the T-Con board.
6. Remove the five screws holding the T-Con board and its metal cover.
7. Carefully shift the metal cover of the T-Con board away from the other metal bar.
8. Two flat ribbon cables connect the display to the T-Con board. Unlock the socket and remove the cables using a plastic lever or your fingernail.

Step 4: Replacing the T-Con Board or AS15 Chip

1. Identify the T-Con number, such as T370HW02 or similar, for your LE37A659 TV model. Search the internet for a spare part to replace the T-Con board.
2. Alternatively, if you prefer to solder the AS15 chip yourself, it is marked in red in the picture. Most similar Samsung TVs have this chip, but its location may vary. You can purchase it as a spare part on websites like eBay. Note that SMD soldering requires expertise and caution.

Step 5: Reassembly

1. Carefully reconnect the flat ribbon cables into the socket and secure them by pushing down the black lever.
2. Reassemble all the parts in the reverse order of disassembly.
3. If you notice vertical stripes on the TV screen that were not present before (refer to the sample picture), the flat cable may not be correctly seated in its socket, or some contact ends might be loose or scratched off. Ensure the cable is properly placed in the socket and fix any issues.

Does Samsung fix broken TVs?

If your Samsung TV screen is damaged, there’s no need to be concerned. We have all the necessary information to assist you in servicing your curved, flat, LCD, LED, QLED, UHD, or Full HD TV. Here are a few steps you should consider before sending your TV for repair:

Assess the damage: Carefully examine the cracked screen to determine the extent of the damage. Take note of any visible cracks, lines, or discoloration.

Check the warranty: Review your Samsung TV’s warranty to see if the screen damage is covered. If your TV is still under warranty, contact Samsung’s customer support for guidance on the next steps to follow.

Contact a professional: Reach out to an authorized Samsung service center or a qualified technician to discuss the issue and seek their advice. They will provide you with the necessary guidance on repair options and cost estimates.

Backup your data: If possible, back up any important data or settings stored on your TV. This step is essential to ensure you don’t lose any valuable information during the repair process.

Consider repair versus replacement: Depending on the severity of the damage and the cost of repair, you may need to evaluate whether it is more practical to repair the cracked screen or invest in a new TV. Consult with the professionals mentioned earlier to make an informed decision.

Remember, it’s important to exercise caution when handling a damaged TV screen. Avoid applying pressure or attempting DIY repairs, as this can cause further damage. Seek professional assistance to ensure a safe and effective resolution to the issue.

How long should a TV last?

Let’s imagine you bought one of our highly recommended affordable televisions, the TCL-5 Series.

In terms of its internal components, this TV consists of various parts, but typically, the LEDs in its backlight are likely to be the first to fail. An LED’s average lifespan, when operated at maximum or near-maximum brightness, ranges from 40,000 to 60,000 hours, which translates to roughly 4.5 to 6.8 years. Assuming you don’t watch TV 24 hours a day (and we hope you don’t), an LED TV like the 5-Series could last approximately 13 years if none of the other components fail before then.

However, there’s a significant caveat. Almost all TVs available today are smart TVs that run on an operating system. Like any software, your TV’s operating system requires regular maintenance through firmware updates. Eventually, a manufacturer might discontinue support for a mid-range TV released five years ago. After all, it has been five years, and the company prioritizes supporting its newer TV models.

The quality of a TV’s software and the frequency of firmware updates vary depending on the brand. This, along with the likelihood of receiving better quality hardware components, is why we recommend purchasing a TV from a reputable and well-known brand.

Even if you limit your TV usage to eight hours a day and manage to maintain the LEDs in good condition, your TV might start encountering issues around the six- or seven-year mark.

Is that lifespan sufficient? It largely depends on the TV’s cost and how eager you are to keep up with the latest technology. In the realm of TV technology, five to seven years is considered quite a long time. For instance, seven years ago, you would have had to spend approximately $800 for a 50-inch full-HD TV. Nowadays, you can purchase a 55-inch, 4K/HDR TV for less than $500.

Moreover, you might come across certain advancements in TV technology that are too enticing to ignore, particularly if you are an audio/visual enthusiast or an avid gamer. The Xbox Series X and PlayStation 5, for instance, support features that weren’t even available on most TVs just six or seven years ago. Even if gaming isn’t your primary interest, you’ll likely want to upgrade to a larger and better TV before your current one eventually becomes obsolete.

That being said, if you want to maximize the lifespan of your TV, there is a simple way to keep it in good working order.

The T-con board in a television is responsible for controlling the timing and synchronization of the image displayed on the screen. It plays a crucial role in ensuring a clear and accurate picture quality.
