Short Killer Remove from Panels

 بِسْمِ اللهِ الرَّحْمٰنِ الرَّحِيْمِ “In the name of God, the Most Gracious, the Most Merciful”

Short Killer Panels

Namely eliminating short paths inside the LCD panel using Short Killer Device from outside

This case is often  told by many technicians

But  it seems like no one has ever uploaded our technique... or maybe no one has ever done it...

Dark screen problem on earless Cof less panels.

Cutting left-right gate-driver lines or left-right isolation......we often find the results  don't work.

So the "short  killer panel" is the last profitable business that you can try.         

For example the Samsung panel.

Look at the picture of the paths that can be found on the SAMSUNG panel without ears on the left and right.

The major lines from top to bottom are lines ckv1, ckvb2, ckv2, ckvb2, vss, stvp

Then there are small soft lines that cross between the lines to a series of Vertical Shift Register circuits. 

To find out if it's short or not then:

• Cut all Ckv, Ckvb lines on the left and right sides, using Digital AVO in the DIODE CHECK position.
  
• Check the resistance between lines (ckv1-ckvb2) and between lines (ckv2, ckvb2). Normal measured resistance is INFINITE (using digital AVO shows "OL")
• If it shows the ohm value, it means the path is short.

 

How to shoot the short route.

• Use Short Killer Device with a voltage between 15v to 30v/5A..
• Because of the CVK path. ckvb is very soft and close to other lines.....don't shoot directly at the printed line..........the mistake of sticking to another line is the risk of being shot.

• Attach a cable connection that is long enough on the path that will be shot (it is best to use a soft cable such as used DVD motor email).
• The ends of the soldered wires at the PCB cuts have holes.
• Then what we shoot are the ends of the cables that are soldered to  the hollow PCB.
• Shoot by   shooting.
• Do it again  if the short remains stubborn.

 Circuit Short Killer Device 

A circuit short killer refers to a device or technique used to identify and troubleshoot circuit shorts in electrical systems.

It helps in locating and fixing the faulty circuit that is causing the short circuit.

Here are a few common methods used to find circuit shorts:

1.

Visual inspection: Start by visually inspecting the electrical system, including wires, cables, connectors, and any exposed or damaged areas.

Look for any signs of burned or melted insulation, exposed wires, or loose connections.

2.

Circuit breaker test: Turn off all the circuit breakers in the electrical panel and then turn them on one by one.

If a circuit breaker trips immediately after turning it on, it often indicates a circuit short in that particular circuit.

3.

Multimeter testing: Use a multimeter to test the resistance, continuity, and voltage at different points in the circuit.

Compare readings between different components to identify any variations that may indicate a short circuit.

4.

Divide and conquer: If the circuit has multiple devices or outlets, disconnect them all and then reconnect them one by one, testing for a short circuit after each connection.

This helps to isolate the problematic device or outlet.

5.

Short circuit locator: There are specialized tools called short circuit locators or circuit tracers available in the market.

These tools emit a signal that can be traced along the length of a circuit to pinpoint the location of the short circuit.

Remember, working with electrical systems can be dangerous.

If you are not confident or experienced in electrical work, it is recommended to seek professional help from a licensed electrician or technician.

6: Short Circuit Remover Tools

You can remove short circuit in electronics circuit by short killer tools as shown in this pictures 

Dead, means No output and no response on output.

Missing particular voltage.

Voltage fluctuation.

Shorting in the primary section.

Secondary section shorting.

Main Capacitor Blast and weak.

STR Mosfet error.

Blast STR IC.

These are the common fault which we get in the LCD LED TV. Now I will tell you how you can fix this type of fault very easily. I already repair many power supply board. If you want to watch my PSU repairing video click here and learn how I repair power supply and fix the TV.

Repairing Process

DEAD: For dead power supply repairing first of all you have to check all the components. Mostly PSU getting dead when some components getting overheating or burn. Find the bad components and replace them with a new one. Especially mostly time we get a fault in the main STR Transistor which use for voltage switching. And lastly you have to check the feedback Schottky diode. Many times this diode also getting overheat and burn, after that stop the voltage flow. for more information click here.

Missing Particular Voltage: When you get some specific particular voltage is missing in the PSU, you have to check that track. For example from PSU we get many values voltage like 5v, 3.3v, 12v, 24v. If any of this voltage is missing in the LCD LED power supply, check that particular voltage which you not getting from PSU. This type of specific voltage missing problem you fix very easily if you know about tracing the track. Mostly I fixed this type of problem by doing to replace the capacitor and transistor and voltage regulator replacing.

Voltage Fluctuation: This means the output voltage is not stable and not pure DC. To repair this type of fault you have to check the voltage rectification section. Firstly check the main primary section capacitor. Seeing such a rectification problem for this fault. This type of problem also arises because the capacitor is weak. If the capacitor is getting weak simply replace that capacitor. Your LCD LED TV Power supply fluctuation problem will be fixed.

Shorting in Primary and Secondary Section: It is very simple to fix this type of shorting problem. Only you have to find out the sorting components and replace them with a new one. That’s it your power supply will be fixed.

Main Capacitor Blast and weak: High voltage damage in LCD LED power supply is that blast the main capacitor or blast the main STR Transistor. When you open the TV first you will see the capacitor is a blast. This problem only gets when a huge amount of voltage will flow in the circuit. For repairing this problem first change the fuse and capacitor. Before the test the circuit also checks the STR Transistor. Many times STR also effected by the overvoltage input signal.

STR Mosfet error: This is most getting a problem in the LCD LED power supply. If you get 10 Dead LED TV for repairing, 6 will be the STR error problem. In my 12 years of repairing experience I have repaired 1000+

  The working principle of an LCD (Liquid Crystal Display) TV screen involves the use of liquid crystals to produce an image.

Here are the key steps involved:

1.

Backlighting: The LCD screen has a backlight behind it to provide illumination.

This backlight is typically fluorescent or LED-based.

2.

Polarization: The light produced by the backlight is then passed through a polarizing filter.

This filter allows only light waves vibrating in a specific direction to pass through.

3.

Liquid Crystals: The polarized light passes through a layer of liquid crystals.

These liquid crystals are like a viscous fluid that can be controlled by applying an electric current.

When no current is applied, the liquid crystals are in their natural state, which twists the polarized light.

4.

Electric Current: The LCD screen has an array of thin-film transistors (TFTs) and electrodes behind it.

When a specific TFT is activated by applying an electric current, it allows the corresponding electrode to apply a voltage to the liquid crystal pixel above it.

5.

Pixel Control: The voltage applied to each pixel controls the orientation of the liquid crystals.

This manipulation changes the polarization of the light passing through the liquid crystals, either allowing or blocking it from passing through to the next layer.

6.

Color Filters: In full-color LCD screens, there are red, green, and blue color filters located in front of each pixel.

By controlling the voltage applied to each pixel, the amount of red, green, and blue light passing through is adjusted to create a desired color.

7.

Viewing Angle Control: Additional layers, such as diffusers and waveplates, are placed in front of the liquid crystals to control the viewing angle and enhance the image quality when viewing from different angles.

8.

Image Formation: As the polarized light passes through the liquid crystals, voltage-controlled pixels determine the amount of light transmitted.

By controlling the orientation of these pixels, various shades of color and brightness are produced, forming the image on the screen.

9.

Refresh Rate: The LCD screen repeatedly applies electric currents to the liquid crystals to refresh the image on the screen.

The refresh rate determines how quickly the image is updated, typically measured in Hertz (Hz).

Overall, the working of an LCD TV screen relies on the manipulation of liquid crystals through electric currents and various layers to create and display images in vibrant colors and detail.

VGH stands for Vertical Gate High.

It is a voltage used in liquid crystal displays (LCDs) to control the horizontal position of the liquid crystal molecules.

VGH positive 24V to 29V as per panel size

The exact voltage needed for VGH depends on the specific LCD display technology and manufacturer

VGL is the abbreviation for Gate-to-Source Voltage Low, Negative Voltage 

 which refers to the voltage applied to the gate terminal of a field-effect transistor (FET) to control the flow of current between the source and drain terminals.

It is commonly used in the context of FET amplifier circuits and is typically specified as a range of values, such as -5v to -11v
