If you get dead TV faults in any kind of LCD LED TV then you have to do the below steps for LCD LED TV repairing the problem.
First Step: The first step is, you have to check the power cable for leakage. If you get any leakage or damage the cable simply change the power cable, your TV will be fixed.
Second Step: After that you have to check The Power Supply Unit. Because when we repair the dead problems of any LCD LED TV 90% cases we get from power supply failure.

For main motherboard checking you have to provide power supply externally according to the motherboard voltage. If your motherboard needs 12v for operating then simply provide 12v supply to the motherboard. If your motherboard has in good position it will be turned ON otherwise getting no response.
Car Radio Problem?
............................................................................
If the radio won’t work, make sure the car battery is fully charged. Also look under the dashboard for any wires that may have become unplugged.
If the sound is fuzzy, disassemble the unit and locate the volume control; spray electrical contact cleaner into the control and rotate or slide the control several times to lubricate the mechanism. Replace a damaged or broken antenna (see below).
If the radio signal crackles, check the antenna for a tight connection. Check the battery ground connection to make sure it is tight. Also, find and replace the noise-suppression filter on or near the alternator. You’ll need the car owner’s manual, a service manual, or a helpful auto parts clerk to find and replace it.

Remember to clean the your car’s cassette deck and CD player at least twice a year, depending on how much you use them. Use a cassette tape cleaner or CD cleaner kit as recommended by the manufacturer.
What Do I Need for Car Radio Repair?
Most modern radios are built on printed circuit boards that can’t be repaired by anyone but trained technicians. However, there still are tests you can perform and parts you can replace. Check your local auto parts supplier or electronics supplier for parts and tools. Here’s what you’ll need:
01. Screwdrivers
02. Wrenches
03. Electronic contact cleaner
04. Denatured alcohol
05. Soldering iron and solder
What Are the Steps to Car Radio Repair?
________________________________________
01. Diagnose clicking noise on your car radio:
If the sound is a high-pitched whine that gets higher as the engine speeds up, the cause is probably a defective noise-suppression filter. Buy an exact-replacement unit from an auto parts store and make sure it has installation instructions included.
02. If the sound is a ticking that doesn’t get higher pitched but does become more frequent as the engine speeds up, it’s probably defective spark plug wires or a defective ignition coil capacitor. Purchase the replacement parts from an auto parts store that can advise you on installation.
03. Replace an external car radio antenna:
Loosen the antenna mounting nut on the car fender and remove the antenna. If there is no mounting nut, you may need to access it from the underside of the fender. In some cases, you will need a special tool to remove the nut.
Follow the manufacturer’s instructions for installing the replacement antenna.
Replace a built-in car radio antenna:
You can’t. Many automotive antennas are built into the frame or body of the car. To determine if your car’s antenna is replaceable, check the owner’s manual or ask an auto parts clerk.
Remove a car radio:
There are many models and installations, so this is a general discussion. Car radios typically are held in place by brackets. A face plate is a decorative cover that hides the fasteners (screws and nuts) that hold the radio onto the brackets. Once removed, the radio unit will slide toward you, allowing you to unplug electrical connections to the power, the speaker, and the antenna system. Fortunately, most modern car radios are interchangeable and include installation instructions.

Hi all guys!!!!
Today I am going to teach you how to fix a TV that has a backlight problem Here you can see I am using a backlight tester I made
I am using a very simple method in this repair I hope you can easily understand that Let's go to the lesson now. đ
Once the LED TV is turned on, the display turns on and off On my inspection I noticed that a capacitor on the main board was malfunctioning But I kept checking the voltage to see if there were any more such issues.
There I had to check the two backlight straps but I made sure the backlight straps were not damaged . I checked the main board capacitor again, removed it and connected a new one. Again I checked the voltage and there I noticed that the repair was successful.
What I needed to do here was to train you to deal successfully with a problem like this. I hope you got it successfully by watching this video

LG TV standby Probe 200V does not run out of 200V The diode and pf in it are destroyed and as a result it stops running at 200V This causes the TV to stand out in standby mood
