TV Capacitor Problems

A capacitor is a passive electrical component, used for the function of storing energy in an electrical field. All capacitors consist of two electrical conductors separated by an insulator called the dielectric. The numbers on the capacitors indicate the amount of current the capacitors can hold. They are used in almost every electrical device for the purpose of designing circuits, reducing noise, storing power and providing flexible filter options. Below are frequent asked questions on issues relating to TV Capacitor Problems that has been answered by the Experts.

Could it damage any component on the power supply of a Plasma TV, if the 3300uf 10V capacitor is replaced with a 3300uf 6.3V?

In this case, if the operating voltage of the capacitor is 5V, you can use the 3300uf 6.3V capacitor. However, if the voltage operates at 10V, then your capacitor is highly probable to short circuit or blow up. Alternatively, if you could use three 1000uf capacitors of a higher voltage and connect them in parallel, most likely it should work.

Why would the capacitor of a Samsung TV ballast swell again a few days after being replaced?

Case Details: I also replaced the ballast but after seven days, the capacitor got swelled again? 

In this case, since there is a continuous power supply to the capacitor, it will tend to swell. Moreover, if you trace these capacitors from the ballast power connection to the power supply, you should find that there are two large filter capacitors near the power supply connection. If out of these two filter caps, you find one is swollen this would probably be your problem.

If a 250V 820uf was replaced on a TV to a 200V 820uf capacitor, and the TV will now not power on, could it because of changing the capacitor on the board?

In most cases, this could be the cause of the problem since the voltage does matter, you would find that the capacitors on the board inside the TV set have the lowest possible voltage when they are manufactured. Therefore, in a situation like this, the best thing to do is replace those low voltage capacitors with a higher one. This is because a capacitor with voltage less than 250 may cause damage to other components inside the TV set. However until and unless the physical dimensions do not differ, a higher voltage cap on the board does not matter.

If the capacitor on a Samsung TV went out or blown, there is no picture on the TV but does have sound, could the failure be related?

In this case, it looks like the blown capacitor is situated on the X or Z sustain board. Usually, if one of these boards fails to work, there is a possibility that such symptoms may occur. Therefore, in order to know if the capacitor failure is the only cause of the picture problem, you would need to get in touch with a skilled technician who can not only perform an on-site diagnosis of the entire problem but should also be able to let you know its exact cause. Moreover, single component replacements are no longer done. Thus, a skilled technician would help to replace the entire board for you as well. Therefore, the best thing to do, in this situation, is to make a call to Samsung and ask them to send you a technician. Now, in case you find out that this is the only issue that is causing the problem, you can expect to pay around two hundred dollars for the repair. You could call Samsung Customer Support at 0330 SAMSUNG (7267864). They are open from Monday to Saturday from 9 am to 6 pm.

A capacitor is an important component in an electrical device used for controlling the electrical current. However, despite its wide use, these capacitors seem to have their share of problems. They have a high tendency to fail violently under certain specific conditions. They may even destroy other electrical components and cause electrical shocks that could be fatal to the users. Sometimes, if your component fails or refuses to turn on, it may be due to a failed capacitor. If you need clarification about your specific situation with respect to issues related to TV Capacitor Problems, you may ask a TV Technician expert to evaluate your case details and provide a technical insight.
