TV repair in Vilnius: how to check and replace capacitors

One of the most common faults with TVs is related to capacitor problems. Capacitors are essential electronic components that help regulate current and voltage. In this article, we will discuss how to check and replace capacitors if you live in Vilnius and experience such a fault.

Signs of capacitor failure

First of all, it is important to recognise when capacitors can be a problem. Here are some of the most common signs of capacitor failure:
- The TV doesn't turn on, or turns on and off by itself.
- The screen shows image distortions or banding.
- There is a strange hissing or popping sound.

How to check a capacitor

Before starting any repairs, it is essential to switch off the TV and disconnect it from the mains. The following tools will be needed for the inspection:
- Multimeter (current meter).
- Soldering tool set.
Here's how you can check capacitors:
1. Open the TV case to access the circuit board containing the capacitors.
2. Visually check the capacitors. Look for swollen or leaky capacitors.
3. Use the capacitance function of the multimeter and connect it to the capacitor contacts. If the reading differs significantly from the indicated value, the capacitor is defective.

Replacing capacitors

If you find that the capacitor is defective, it will need to be replaced. Here's how to do it:
1. Switch off the TV and unplug it from the mains.
2. Use a soldering iron to remove the old capacitor. Remember to be careful not to use too much force.
3. Insert the new capacitor in the same place, noting the polarity (plus and minus).
4. Solder the new capacitor, ensuring good contact.
5. Cover the TV case and connect it to the mains.
