 Model: Samsung UNxxC9000 LED TV

Symptom: The UNxxC9000 LED TV power up sequence
Repair/Solution:
This power up sequence can help you troubleshoot the UNxxC9000, here is the power up:
a. When the AC cord is plugged in, the voltage on the STBY pin goes to 5.3V.
b. The MCU (Microcontroller, Micon &etc) on the mainboard actively looks for the user to press Power On switch from remote control or the TV itself.
c. When a user presses Power, the MCU sends a “High” voltage (0-1.2V transition) to the SMPS/PSU via Power_On/Off pin to activate the rest of the voltages.
d. After the 0-1.2V transition on the POWER_On/Off pin, the following voltages are activated on CNM801 and the “Melody” plays.
- Vamp= 18VDC
- OD_On/Off= 3.3V
- D5.3V = 5V
- D12V = 13V
e) Approximately two seconds later, 5V is applied to the BLU_On/Off pin.
f) Once the BLU_On/Off pin is activated, the LED arrays turn on. CNL801 supplies high voltage to the LED arrays. The following voltages are activated on CNL801 (with respect to chassis GND):
- BOT1+ = 170VDC
- BOT1- = 45VDC
- TOP1- = 45VDC
- TOP1+ = 170VDC
- TOP2+ = 170VDC
- TOP2- = 45VDC
- BOT2- = 45VDC
- BOT2+ = 170VDC
g) High voltage is applied to the panel LED arrays though connectors CN401 and CN402:
Pin 1 and 12
-Approximately 170VDC (when referenced to the chassis GND).
-Voltage varies when referenced to connector GND.
Pin 6 and 7
-GND (effective).
-Approximately 45VDC when the backlight is lowest.
-GND Pins
-GND Potential is highest when signal is >90% duty cycle (almost DC).
-GND Potential is lowest when signal is <10% duty cycle (almost GND).
-Level is controlled by the mainboard though the Bot_Dim and Top_Dim pins on connector CNM801


Model: Samsung LN19C350DXZA LCD TV
Symptom: Display is completely Green color only.
Repair/Solution:
LVDS cable not properly inserted or dirty in the contact pins. Clean the LVDS cable contact pins and connect it back properly.


Model: Samsung UN46C6300SF LED TV
Symptom: No Power
Repair/Solution:
This ICB801 (ICE3BR1765J) Power IC is defective on the PSU board.


Model: Sharp LC26SA1E, LC26SD1E, LC32SA1E, LC32SD1E, LC42SA1E, LC42SD1E LCD TV
Symptom: No Display, Sound Problem or Various operational key issues
Repair/Solution:
If after checking the whole PCB boards in TV still not solve the problem, it could be software issues.
Update the main software to the latest version, following the instructions in the service manual. Or using an ISP Programmer to empty their EEPROM IC first, if problem still the same, then you should program their flash memory by ISP Programmer with the working firmware.


Model: Sharp LC46D78UN & LC52D78UN LCD TV
Symptom: HDMI Connectivity Issues: No Sound or No Display When Turned On
In some cases, when connected via HDMI to an external audio amplifier or set top box an interruption to the sound and display may result when the TV us turned off and back on. This may occur due to current leakage from the HDMI-SW IC VHISII9287+-1Q on the mainboard.
Repair/Solution:
When the TV set requires service due to the above mentioned symptom, replace C1614 (0.1uF, 104 ceramic capacitor) on the mainboard with a 1K ohm1/16W resistor to reduce the leakage effect or just replace the mainboard.

LG 32LC56: Picture divided into several parts. Distorted picture

BUSH LCD26TV006HDX: No display. Flashing standby light
Model: BUSH LCD26TV006HDX LCD TV
Symptom: No display. Flashing standby light.
Cure/Solution: The capacitor C315 (1000uF/25v) is supplied higher rated, and is a little bigger so use longer leads don't fit close to board. Be careful when soldering you don't accidentally remove the tiny surface mount resistors on back of board.

Samsung LN32A330: The TV takes longer to power on than normal
Model/s: Samsung LN32A330J1DXZA,LN32A330J1NXZA LCD TV
Symptom: The TV takes longer to power on than normal
The TV takes longer to power on than normal. You may hear several clicks while the TV attempts to power on.
Cause: The electrolytic in the capacitors on the power supply board over time will dry out causing the power supply to shut down during its initial power on cycle.
Cure/Solutions: Refer to the capacitor cross reference guide below for the list of the capacitors that should be replaced.

Samsung: Unit tries to start with melody but cycles off and back on
Model/s: Samsung LN40A650A1FXZA,LN46A650A1FXZA,LN40A750R1FXZC,LN46A 750R1FXZA,LN40A750R1FXZA LCD TV
Symptom: Unit tries to start with melody but cycles off and back on
Cure/Solutions: If the unit tries to turn on and makes the startup melody but then immediately shuts off and starts again, unplug the LVDS cable and apply power again. If the set stays on, replace the T-Con board.

Circuit Short Killer Tricks

 Circuit Short Killer 

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.

Redeem Your Bonus Points of Downloading 

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+

PWM Regulators Guide

 

PWM IPS in the housings SOT-23-6, SOT-26, TSOP-6

By Imran Ashraf Khan

In the circuitry of modern pulsed power supplies (SMPS), PWM regulators, made in small-sized planar cases with six terminals, have gained wide popularity. The body type designation can be SOT-23-6, SOT-23-6L, SOT-26, TSOP-6, SSOT-6. The layout and layout of the pins are shown in the figure below. In this case, the left fragment of the picture shows the code marking LD7530A

Pin Assignment: 
1 - GND. (Common wire). 
2 - FB. (FeedBack - Feedback). Input for controlling the pulse duration with a signal from the output voltage. Sometimes it can have the designation COMP (input comparator). 
3 - RI / RT / CT / COMP / NC - Depending on the type of chip, it can be used for a frequency-assigning RC circuit (RI / RT / CT) or for protection, as a PWM tripping comparator input with a threshold value at its input, specified in the document. In some types of microcircuits this input can be not involved in any way (NC - No Connect). 
4 - SENSE, different CS (Current Sense) - Input from the current sensor at the source of the key. 
5 - VCC - Input voltage supply and start the chip. 
6th - OUT (GATE) - Output to control the gate of the key.

Functionally similar regulators work on the principle of popular earlier PWM chips xx384x series, which have proved themselves in terms of reliability and stability.

Some difficulties often arise when replacing or selecting an analog for similar PWM controllers due to the use of code marking in the designation of the type of microcircuit. The situation is complicated by a large number of component manufacturers, which do not always provide documentation for mass access, and not all manufacturers of ready-made devices supply repair service centers with circuits, so real repair schemes often have to be studied by repairers on the installed components and wiring connections directly on the board.

In practice, PWM chips and EAxxx and Eaxxx marking codes are often found. Official documents on them are not found in free access, but discussions on the forums and pieces of pictures from the PDF from System General, which publishes them as SG6848T and SG6848T2, have been preserved. The picture is attached.

To the attention of the masters we offer tables made up of information available on the Internet and PDF documents for the selection of analogs when replacing the most common six-legged planar PWM with pinout: pin1 - GND, pin2 - FB (COMP), pin4 - Sense, pin5 - Vcc, pin6 - OUT . 
Their main difference is the application and purpose of the output 3.

How to read LDO LCD 8-pin regulator code 00HC5W

• This kind of regulator is often found on the Toshiba LCD motherboard, and the shape is similar to ic eeprom.
• The BD writing code is not written on the physical ic regulator. So for example just written 00IC0W, 00IA5W

How to read the specs: For example say 00HC5W

(1) Code "00" This means that the output voltage variable or can diajust by changing the value of the feedback resistor. 
(2) The "H" code indicates that the maximum input allowable voltage is 10v. 
(3) The code "C5" indicates that the maximum current capability of 1.5A 

Example usage:

• Input Voltage: 8.0v
• Output voltage: 1.5v to 7v - can be obtained by changing the value of R1 / R2
