LCD Panel Short Killer Guide

  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+

Fault Findings common troubleshooting

With the advancement of science and technology, TVs have changed a lot from the earliest black-and-white TVs to color TVs and now to today's LCD TVs. However, after a TV has been used for a period of time, various malfunctions cannot be avoided. Today I will introduce Here are some repair methods for you if your LCD TV breaks down, let’s take a look!

Welcome to follow the WeChat public account "Hotwater Heater Repair Phone Number" to get more home appliance repair information!

1. TV hardware failure - TV screen is black and there is sound

Solution: Check the plugs on the back of the TV to see if each plug is in a specific position, and confirm if there is any looseness at the socket. If so, just fix it.

After troubleshooting the socket problem, if the black screen of the TV has not been resolved, then it is a hardware problem. At this time, do not disassemble it yourself. You must contact the relevant after-sales maintenance personnel for inspection.

2. The TV screen suddenly goes black and cannot be started.

Solution: Observe the power indicator light of the TV. If the power indicator light does not light up, it means a sudden power outage and a black screen due to a power connection problem. At this time, you can check whether there is a power outage at home, whether the power plug is loose, and whether the power cord is faulty.

If the power indicator light is on, it is a hardware problem. Users who do not understand the specific internal structure of the TV need to contact after-sales maintenance personnel for testing.

3.TV screen blur
