If all the sounds coming from the external speakers are fine then it is clear that the internal speakers of the LED TV are not working in the right way. Due to heat up, the audio IC of the internal speaker goes failed.

 

  • Blank Screen

 

This is the most common problem in modern LED televisions. The problem generally arises due to the failure of capacitors on the power supply board. An experienced technician having good experience and knowledge of the components and their configurations can fix this issue of leaking and bulging capacitor with his excellent soldering skills.

 

  • No Connection with WiFi

 

Locate the actual problem if it is related to the television or to the router. Try to connect the mobile with the router. If it is not connecting then update the firmware of the router and reset it. Also, check the LED TV ports for connections and the signal strength also.

 

  • Horizontal Lines on Start-Up

 

It can be due to the poor signal strength coming from your set-top box to the LED TV.  Modern LED TV requires higher input strength of the signal. You can switch to an HD set-top box to rectify this problem quickly.

TV Components And Their Common Problems

A malfunctioning television may cause irritation, leading to a lack of favorite programs or a bubbling screen. You can do some simple repair work yourself, but only if the problem is one that affects most televisions. Currently TV Repair Service requires more complex repairs by professionals. Problems specific to your television type (LCD, plasma or CRT) or brand may also involve the attention of a specialist.

Power supply

The Power Supply Board is usually the largest and heaviest board found inside the LCD TV. Some repair techs call the “Power Supply Unit” and “Power Supply Module” or just “PSU.” It converts the main AC supply into DC voltages which can be used within the LCD TV by the circuit.   The control board is sometimes attached to the inverter board and is known as an I / P board.

Common faults-No power, low power, blink power, and no power intermittent.

Timing Controller Board (T-Con Board)

The T-Con board is the smallest panel in LCD TV and is usually found only in LCD TVs.  T-con board purpose is to control gate and source logic signal to drive TFT LCD. T-Con board is sometimes referred to other names such as “Controller Board” or “Control Board.”

Common faults-White Display, No display, Double picture, Display distortion (black and white vertical bars on screen). Multiple horizontal / vertical lines throughout the camera.

Inverter Board

Typically, the inverter boards are located along the edges nearest to the TV panel and are found only in LCD’s. The function of these boards is to convert the low voltage DC supplied by the SMPS to a high AC voltage (500 to 1500 Vrms) to illuminate the backlights. Such boards can be used either as a single board or as an I / P board.

Common errors-Shutdown after a couple of seconds, Dim screen.

Mainboard

Searching for the circuit board with the audio and video inputs and outputs is the easiest way to identify the main board for TV Repair in Brampton. Sometimes the motherboard is called as a motherboard, main panel, electronic board, scaler board, A / V board, main module, logic board or even A / D board. The purpose is to capture video and audio signals and convert the analog video signals to digital signals that can be transmitted to the T-con board by the LVDS IC (low voltage differential signaling).

Note: The audio / RF Input / Rear Inputs portion is sometimes isolated from the mainboard.

Common faults- No monitor, no colour, after often a screen full of vertical lines, no sound, horizontal lines and frame, sometimes the LCD TV fault (usually display problem) may be due to software problem where you need to update the software.

Jackpack section

The audio signal is sent to the audio processor and the audio amplifier is then transmitted to drive the speakers left and right.

Note: The audio section / RF Input / Rear Inputs is sometimes isolated from the mainboard (as seen in the image above) and is called as the receiving board Jackpack or Signals.

Common faults-No sound, distorted sound, high pitched whine, no TV reception, the channels change randomly to some blocks of channels.

LCD Panel

LCD stands for liquid crystal display (LCD) and is a small, flat visual digital display that uses liquid crystal (LC) light modulating properties. LCs do not emit light directly, making these LCD displays visible requires backlights.

Popular faults-thin line / s or bar vertical / horizontal, white screen, display of garbage.

Backlights (Lamps)

The backlight feature (CCFL or EEFL) is to light the LCD from the back of the display panel.

Common errors-Shutdown after a few seconds and flickering show.

Make sure you check that the television is plugged in before TV Repair Brampton. Make sure the remote has batteries that are new and working. Check to ensure that the TV is not silenced. You should also review the different features and output options on the TV to ensure that they are correctly picked. You don’t want to spend a lot of time and money on something that could be solved by pushing a button.

You can overheat it if you have electronics on top of the TV. The television would probably start breaking off unexpectedly. This is a security mechanism to prevent the entire thing from catching fire. All items should be removed from the top of the TV, objects should be removed from the ventilation stacks, and ventilation stacks should be cleaned with a small vacuum cleaner attachment. Once the stacks are dry, the TV will start working properly again.
