How To Repair Samsung LED TV Power Supply

Samsung LED TV Repairing

Repairing your Samsung LED TV power supply can be a complicated task and should only be attempted by people with electronics experience and a good understanding of safety precautions.

If you have the necessary skills and equipment, here are some simple steps you can follow:

Safety first: i.e. unplug the TV from the power source and wait at least 30 minutes to ensure that the stored electrical charge has dissipated.  Make sure you are working in a well ventilated area.

Identify the problem first: Before opening the TV, try to diagnose the problem.  Is the power supply board the real problem, or could it be something else like a faulty cable or blown fuse?.

Your tools and equipment: Gather the tools you need, including a screwdriver set, a multimeter to check voltage, and a soldering iron if you need to solder your components.

Opening the TV: Carefully remove the back cover of the TV using a screwdriver.  Be gentle to avoid damaging any components or cables.

Then locate the power supply board: Once inside, locate the power supply board.  This is usually near where the power cord enters the TV.

Inspect for visible damage: Look for any visibly damaged components on the power supply board, such as swollen or leaking capacitors, burnt areas, or loose connections.  See details to replace or repair any damaged components.

And check the voltage: Use a multimeter to check the output voltage from the power supply board.  Compare the readings with the specifications given in the TV's service manual  If the voltage is out of range, there may be a problem with the power supply.

Replace defective components: If you identify specific components that are defective (eg, capacitors), you can desolder and replace them with new ones.  Be sure to use correct replacements with the same voltage and capacitance rating.

Soldering: If soldering is required, make sure you have the necessary soldering skills and equipment.  Make sure you solder joints properly to prevent cold solder joints or shorts.

Reassemble and test: After repairing or replacing components, reassemble the TV and plug it back in  Check if the issue is resolved  Be careful during this step, as there is still a risk of electric shock.

Professional help: If you are not confident in your ability to repair the TV, it is safe to seek the help of a professional technician.

Opening and operating a TV can be dangerous, and if done incorrectly, it can further damage the TV or create a safety hazard.

Remember that working on electronics can be dangerous and may void your warranty.  If the TV is still under warranty, it is usually best to contact Samsung or an authorized service center for repairs.
