TV making popping noises and no pictures can be frustrating, especially when watching important information. The most common issue of the Tv producing noise without displaying any image is the distorted Tv capacitor, which is the problem with a faulty LED in the backlight system. Popping noise in most cases indicates a failing Tv or the components of the Tv are damaged.

Tv making popping noise is normal and common in all TV models such as Samsung TV, LG television, among other models. Once you experience TV turning on or off with popping noise and without displaying any picture, first determine the root cause of the problem and use the information in the article below to eliminate the popping noise.

Causes of TV making popping noise and no pictures

Causes Of TV Making Popping Noise

Several reasons may result in your TV making popping noises without displaying any picture. The common causes include;

1. Faulty TV capacitor

Faulty TV capacitor

Each television contains a capacitor that aids in supplying constant power to the television. Once the capacitor fails, there is no regular power supply to the capacitor resulting in the production of popping noise, and the tv won’t display any information. The capacitor fails due to the following reasons; some capacitors fail to withstand high voltages resulting in exposure to the television device holding them. Also, increased temperature levels damage the television capacitor hence reducing its lifespan.

2. Fault LED in the backlight TV system

Once the television backlight fails to function, it affects the screen picture displacement and, in turn, results in popping noise. First, to fix the backlight issue, turn on the television to confirm if the screen is functioning or if pictures are displayed. Using a flashlight very close to the tv, examine the screen and see if you can see the image.

If the image is OK, then the backlight is in correct condition but if it fails, inspect the mainboard to see if it is in a good state. Fixing the backlight problem requires a step-by-step guide with constant reference to the manufacturer’s instructions.

3. Contraction of the internal television parts

Sometimes when you turn off the television, a popping noise is generated; it is due to the contraction and expansion of different internal components such as capacitors. Also, Tv metals may expand and contract, especially during summer or when the temperature of the room increases. The possible solution to fixing the problem is using a thermostat to regulate the temperature in your living room, especially when it rises or falls below the average temperature.

Steps to fix a Tv that makes popping noise but fails to display pictures

Each television is well known for its fault capacitors. Therefore, when the Tv continuously makes noise without displaying any picture, it is advisable to repair the problem on your own before contacting skilled personnel to save the repairing cost for future use, such as during emergencies.

The following steps describe the best ways to troubleshoot the television, making a popping noise and failing to display the pictures. Follow the steps carefully to fix the television popping noise without damaging any component successfully.

Step 1: Collect all materials necessary for eliminating popping noise

The materials required include; a pair of pliers, a television repair kit, a screwdriver for unscrewing and screwing nuts, a wire cutter, and wire stripper, a new capacitor, and a solder. The materials must be of good quality and highly recommendable by the manufacturer to avoid damaging the television parts. For instance, use iron solder because it is affordable and is of good quality. 

Also, consider using additional tools such as an electric screwdriver instead of a regular screwdriver, a solder sucker to remove all solder that is melting during the repair process, and a multimeter for testing the television wires if they are functioning well. Also, you may use a flux pen to allow the solder to flow smoothly without sticking to the cables or wires.

Step 2: Disconnect the television from the power supply

Before repairing the television, ensure you turn off the power supply source and unplug the tv. Hold the television carefully to protect it from falling and breaking. Also, you may use a screwdriver if the tv is mounted on the wall with a screwdriver.

Step 3: Remove the television from the stand

After disconnecting the television and unplugging it, remove the television stand for the televisions that are not mounted on the walls. Handle the frame carefully to avoid breaking it. Also, ensure you pay more attention when laying the tv in a different place. Avoid placing the television near edges to fall and crack easily, thus increasing repairing or replacement costs.

Further, it is advisable to keep the television straight to prevent any pressure from distorting the fragile Tv glass. If by mistake the television cracks, repair the glass or replace the glass first before proceeding to the next steps.

Step 4: Unscrew the Tv back casing cover

Using a screwdriver and a wrench, remove the screws to remove the back casing cover. Sometimes you may find the accumulation of dirt on the screws, making them hard to unscrew with a screwdriver. In such a situation, consider using other tools such as a bolt cutter to cut the rust bolts and dispose of them correctly, following the manufacturer’s disposing of instructions.

Step 4: Disconnect the wiring from the circuit board

The circuit board contains several wiring harnesses, which you need to remove before proceeding to the next step. Using a simple tug, remove all wiring harnesses present in the circuit. Remove the wiring harness carefully to avoid damaging the wires and keep them in a good state for the reinstallation process. Next, locate the position of television capacitors.

Step 5: Examine the condition of the capacitors

Check the capacitors carefully and detect any issues. There are two common issues with the capacitor, and they include; bulging vents and capacitor leaking.  If the bulging vent fails to function, hydrogen gas is produced to damage the aluminum cans. Also, if the aluminum can fail to work, a loud noise is generated.

Secondly, a leaking fluid indicates a poor capacitor. Try fixing the bulging and leaking fluid to eliminate the problem. The fluid is usually brownish, and in other capacitors, it may be orange. If the noise persists or if the vents and electrolytes are good, proceed to the next step instead of assuming and closing the television.

Step 6: Remove the capacitors from their location

Capacitors have both positive and negative terminals, just like other batteries. Therefore, before you remove the capacitors, check the capacitor terminals and see if they are matched correctly with the television terminals. If the problem persists after fitting the terminals, reinstall the new capacitor in the same position and ensure the terminals perfectly match with the television terminals.

After replacing the capacitor, insert the soldering iron and leave it for a couple of seconds, approximately twelve minutes, until the soldering iron melts. Repeat the soldering process a couple of times, and the capacitor will easily slide in its correct position without sticking.

Step 7: Reinstall all components removed during the replacement process

After successfully replacing the capacitor, reinstall all parts removed during the replacement process. Ensure you place each component in its appropriate position and screw the back casing cover back to its position using a screwdriver and a wrench.
