How do you know if the capacitors are bad if they are not swollen and if you cannot really see them because they are covered with a caulk-like material?


CAPACITOR:
A capacitor is a device that stores an electrical charge or energy on its plates. These plates are placed very close together with an insulator in between to prevent the plates from touching each other, and a type of dielectric. A capacitor can carry a voltage equal to the battery or input voltage. Usually a capacitor has more than two plates depending on the capacitance or dielectric type.Once charged the discharge rate can be influenced by another source. This action can create oscillation, or be used for electronic timing. The rate in witch the capacitor charges and discharges can be used to create a filter, or limit unwanted noise. There is lots more we can do with capacitors too.
HOW TO TEST THE CAPACITOR:
There are various methods for testing the capacitors. To short list, I would prefer to use one of the following two methods:
By ESR meter or by multimeter. Assuming that you would not be having the ESR tester just try to test it with the analog or digital meter just to get and idea whether it is defective or not. To test the capacitor do the following:
- Power OFF the device, disconnect it from the mains and wait for 15 minutes.
- Open or desolder one of the legs of the suspected capacitor.
- Take an analog or digital multimeter and set the range on Mag Ohms.
- Touch the probes of multimeter on each side of the capacitor legs and watch the dial (Polarity does not matter in this case).
- The needle of the analog meter or the digits of the digital meter will jump high and then comes back slowly. Reverse the probes and see if this happens again. If this is the case the capacitor is OK.
- If no reading or Zero is found the capacitor is open and is defective. Replace the capacitor.
- If the reading goes high, it is shorted and is defective. Replace the capacitor.
Hope that works. Thank you for visiting Fixya.

I assume you mean you changed capacitors on either the mainboard or power supply. My first question would be why you did this in the first place. If no power then you may have a additional problem other then capacitors. Unless the caps were blown or you tested them with a ESR meter then they might have not been bad.. Or they could have cause another component to go bad or vice versa depending on the circuit. Did you make sure you installed the new caps with the correct polarity? If so.. did you test the new caps with a CAP/ESR meter to make sure they were good? If cap were good, correctly installed, correct polarity, good soldering job.. then there is another bad compotent on the board some where.. with out proper testing it would be hard to say.. usually on & off issues are power/capacitor/mainboard related.

Hi,

Please check your power circuit capacitors for defective. Replace with new one if found it damaged.

LG TV has sound but no picture. what suggestions do you have? LG 55SL80


I would certainly say the power supply has a weak capacitor or two. I have not repaired this particular model. If you can remove the back cover and identify the power supply, you are off to a good start for repair. Look for a bulged or skinned capacitor. If they look fine, you will need an ESR meter to locate the bad capacitors. I would guess that at least two bad caps and there will be two more that are weak. Also, be sure to really, really look for bad grounds on power resistors and inverters, resolder as necessary. Good luck and thanks for asking!

Hi:
Check the power supply ro4 puffy capacitors that look like they are about to burst on their tops, ususally there are two of them that will cause this problem. Replace with same value but change the voltage reating on the capacitor to 16volts.

Bad caps can look normal but it they can have high ESR, but you should take some voltage readings first, it should have 5vdc and 12~16vdc when the monitor is plugged in but not turn on.
Post pictures of the caps also, many people told me the caps look OK until I see the pictures and they turn out to be bad. You need cap meter taht can read capacitance and ESR.

I own a XG-91D monitor that the screen goes black after about 5 seconds. I found 2-470uF 25V capacitors on the power supply board that were leaky - replaced them but the problem still persists. There...


Hello,

Replace thee 1000uf caps too. A capacitor meter will not test the ESR ( equivalent series resistance ) of the caps the cap meter will show them to be good but an ESR meter will show then to be bad. Also be sure to use low ESR caps. If you use general purpose aps like from Radio Shack it can damage the board board because of the ESR rating. The temp rating needs to be 105c or the new caps will blow out within a month because of the heat in the monitor case ( No fans ).

I hope this helps, if so please rate our solution.

Blinking timer light and cannot turn on


How many times does the LED blink? Does it blink 6 times, pauses, and repeats? Or is it some other number of blinks? Or does it just blink continuously, once a second? (Note: on Mitsubishi's it is normal for the TV to blink rapidly for about 90 seconds after you plug the TV in, while the TV runs internal self-tests.) If the LED continues to blink continuously after 90 seconds, then the problem is on the DM board. There are 4 electrolytic capacitors, grouped together. I believe they are either 820 uF (mfd - microfarads) or 1000 uF at 16 Volts. If you check them, you will see that their tops are swollen (slightly rounded; not flat across). They will check okay with a capacitance meter or ESR meter, but don't believe your meter! Replace those 4 capacitors with either 820 or 1000 uF capacitors rated at either 16 or 25 volts. Make sure you use good, high-temperature (105 deg C) low-ESR capacitors. I recommend the "FM Series" capacitors from Digi-Key corporation, part number P12366-ND or P12379-ND. Less than $1.00 apiece. Good luck!

You need to remove the cover and expose the area where the motor sits close to the front, you will find a broken belt, replace that, if you can't get to the screw to remove the assembly, use your fingers or screwdriver to turn the cog so that the drawer is manually opened. make sure power cable is unplugged first.
