You will received a fully functional part
We use three basic criteria in determining good or defective TV parts
1: The power supply must generate a standby voltage (normally 3.5V or 5 V)
2: The main board must raise the voltage from 160 to 360 volts on the power supply
3: There must be an image displayed on the screen.
Meeting these criteria guarantees good parts and virtually eliminates shipping defective parts.
We have additionally supplied diagnostic tips to help you on our Ebay site if required.
Your support will be highly appreciated with a positive feedback and lets us keep our prices low.

Understanding how modern appliances work
Modern washing machines rely on a network of interconnected sensors that work in harmony with the machine?s control unit. The control unit, often a microcontroller or microprocessor, acts as the central processing unit, receiving signals from the sensors and making real-time adjustments to various components like pumps, valves, and the motor. Without these sensors, the washing machine would be blind and deaf, unable to adapt to the specific needs of each load. This could lead to inefficient cleaning, damage to clothes, wasted water, and even potential hazards.
If a sensor fails in a washing machine, it can lead to a variety of problems depending on which sensor malfunctions. For example, a faulty pressure sensor might cause the machine to overfill or underfill, while a malfunctioning temperature sensor could result in inadequate heating or overheating. An imbalance sensor failure could lead to excessive vibration and potential damage to the machine.
In most cases, the washing machine?s control board will detect the sensor failure and display an error code on the control panel. This error code can help diagnose the problem and guide repairs. Depending on the nature of the failure, the machine may be unable to complete a cycle, or it may continue to operate with reduced performance or potential for damage.

PLEASE DO NOT MARK AS DEFECTIVE
Please be sure that the BOARD Part Number AND SERIAL NUMBER are EXACT to the one you are ordering, some models have different boards. Do not match by TV Model. There are possibly several different boards for each model TV. All items are tested and guaranteed to work.?
Diagnostic tips:
1.Symptom: TV has sound, but no picture or looks like it is coming on(from the light(s) on the front panel), but the screen is dark or there is no picture. Tip: Try shining a light on the front of the TV after you turn it on. Do you see a faint picture? If not, it may just need a circuit board replacement. If you do see a picture, then the back lights is most likely that powers the back lights is at fault.
Symptom:TV is dead. There are no lights that come on anywhere when you plug the TV in to a power outlet and press the power button. Tip: This can be caused by a blown fuse from a surge or lightning, but most often it is caused by a defective main board
Symptom The TV light flickers on and off this is normally a back light problem , sometimes the power light will change from red to blue you can normally verify this by testing the voltage on the large capacitors on the power supply it should be about 360 volts (CAREFULL)
Symptom: the red light does not change colour, this may be a power supply or back light problem if there is a short on the back lights the main board will shut the TV down (a safety feature to prevent fires) try disconnecting the back lights and testing the 360 voltage
Symptom:The HDMI ports are not functioning or not functioning properly. Tip:Most often, the problem is with the main board. Most main boards contain all of the HDMI ports, so replacing it will fix the problem 98 percent of the time. HDMI ports are often damaged by lightning. The top tech reports that about half the jobs he assesses that have lightning damage involve main board replacement because HDMI ports are non-functional even though the rest of the TV operates normally.
Symptom:The TV appears to be in an endless cycle of coming on and going off by itself showing the logo only. Sometimes the cycle ends with the TV staying on or going off. This is normally a main board problem
Note: when changing the back lights: the screens on the TV is very fragile and would suggest you watch a video on u tube before attempting . When changing the back lights on 55 inch and up screens: they are extremely difficult to change and require two people and four suction cups: One model of TV uses different back lights so check the part number on the back light strip before ordering
IMPORTANT ALL MAIN BOARDS MUST BE UPGRADED TO FUNCTION PROPERLY FAILURE TO DO SO WILL APPEAR AS A DEFECTIVE BOARD
Changing a part on a TV is not like changing a light bulb most TV's are software driven and require an upgrade from the mfg (to match the new part to your TV) without this upgrade your back lights, WiFi, sound etc may not work properly or fail prematurely. If you have vertical or horizontal lines on the screen it is a screen problem, changing the t-con will not help
These are suggested tips only and are not always the solution TO ALL PROBLEMS
YOU CAN ALWAYS RETURN THE PART FOR A REFUND BUT PLEASE DO NOT INDICATE DEFECTIVE IF YOU LIKE THE DIAGNOSTIC TIPS AND ADVICE A positive feedback would be appreciated THANK YOU
