The importance of quickly solving image and sound problems on TV
Television is an inseparable part of the home. Any failure in the image or sound immediately causes displeasure of family members. LG and Samsung TVs, despite their high quality, may have problems in the image circuit, backlight, main board or sound system after a few years of continuous use. Solving these problems, if done at the right time, will prevent the heavy costs of replacing parts. For this reason, the motto of the Signal collection is: Resolve LG and Samsung TV image and sound problems in less than 24 hours with real warranty and original parts.
Signs of failure in the TV image
Deterioration in image quality usually has specific symptoms. Knowing these things helps to diagnose faster:
1. Complete interruption of the image but the presence of sound
In this case, the backlight or the power supply of the backlight part has failed. This problem is common in LG and Samsung LED TVs.
2. Discoloration or light spots
If a white or purple halo is seen in the image, the panel or optical filter is damaged. Fixing it requires opening the screen and changing the filter.
3. Image jump or horizontal lines
This problem is usually caused by the flat panel or IC driver. The signal team checks and repairs the output voltage at the device location with special equipment.
4. The TV does not turn on
The TV turning off with a flashing light is related to the main board or power failure. Detailed investigation requires a voltmeter.
All kinds of sound problems in LG and Samsung TVs
Sound failure is as annoying as picture failure. Common causes include:
1. There is a picture but the sound is completely cut off
This condition is usually caused by the failure of the amplifier board or speaker output. The signal repairman fixes the problem by resetting the audio circuit and replacing the IC.
2. Buzzing sound or sudden noise
When the input or HDMI cables have a connection or the ground of the device is jammed, a strange sound is created. Cleaning the connectors is often enough.
3. Unbalanced sound on one side of the TV
Due to the burning of the right or left speaker, the playback sound will be out of sync. The team tests the signal of the speakers and replaces them if necessary.
Why is it important to repair faster?
Delay in solving image and sound problems of LG and Samsung TVs can cause other damages. For example, if the backlight failure is not fixed quickly, it will put pressure on the panel and cause many times the repair cost. Or noise in the audio section may cause the audio IC to burn.
For this reason, service-tv.ir by providing the service of resolving LG and Samsung TV image and sound problems in less than 24 hours, it tries to turn on your device again the same day.

The difference between repairing LG and Samsung TVs
Both brands are among the best in the TV market, but the design of the boards and their image structure are different.

- Samsung TVs often have VA panels and more complex mainboards, as a result, audio failures such as right channel interruption or noise are more visible.
Experts of service-tv.ir with detailed knowledge of both structures, perform the repair according to the factory standard.
Preventive tips to avoid audio and video problems

- During a storm or power fluctuation, disconnect the TV from the outlet.
