Looking to fix LCD TV. Need in circuit cap tester. Can this be used if caps are discharged? Is there a definitive answer out there? Thanks.

It is a piece of crap. I wish that I had not bought it. It can barely test caps OUT of the circuit. It is non-intuitive and strange to run. The factory was of minimal help. It comes with no instructions and even the button caps don't fit. Next time I'll spend the bucks for a real tester. I waited to long to test and return it.

si hay que retirar o quitar el condensador de la placa descargalo y despues probarlo, no sirve para probar directamente en la placa

Yes....this device will give a read out of the cap which will be used to determine if the cap is defective based on the the rating indicated on the cap.eg: if the cap is rated at (4700 uf) and a reads (3500 uf )....cap is defective.

The kit shows the capacitor microfarad and voltage capacities for each capacitor. The kit is made for your particular TV. All the brands are very similar in their power supplies. Good luck. You should have success as long as you can solder.

My screen would come on briefly and go black. The 2 main capacitors for the power supply were bad. It took 15 min to unsolder old capacitors and solder new ones and works perfectly. I have the other just in case for a fraction of what I would have been charged to diagnose the problem. I would say yes if that's your problem.

It can't do anything but help. I saw a flat panel's power supply inoperative because of inferior Chinese capacitors that had domed up, and it came back fine with new caps. Would filtered power have helped in that particular case? Who knows? I hear my LE1200 click occasionally, which tells me its relays are doing what they need to do to replace, just for a second or less, "bad" power coming into the outlet to protect my caps and other components. This is NOT an uninterruptible power supply, of course, but a filter against spikey power and brief under- and over-voltage situations. I use these on two TVs and a PC. No way to know for certain what effect they have had, other than my piece of mind, which is worth every penny they get for these jewels.

No it doesnt work and this type DLp uses a lamp that is solder to the cirCUIT BOARD THE ENTIRE UNIT MUST BE CHANGE ,BUY A TV DONT WASTE A MINUTE TRYN TO REPAIR

In my opinion, no. Unless you know the exact circuit configuration and can definitely rule out parallel impedance or nonlinear components around the cap. There is quite a bit of info online about the tester and the signals used to execute the tests if you google around. Here is one example. It is in German but google will translate for you: http://www.mikrocontroller.net/articles/AVR_Transistortester . There is more if you look. I, myself, do not use this device for in-circuit testing.

If you call Samsung now they're aware of the problem and are taking care of it. My TV has been out of warantee for about a year now but they're sending a tech to fix it at no cost as long as it is indeed the capacitors that are faulty.

No issue with them yet. If there were, I think I would replace it with one rated for the next higher voltage. This use to happen with some TV's I use to repair, that was the fix. Good luck.

Yes, for all practical purposes. Incredible, inexpensive device accurately measures R, L and C with high precision. Caps test provides capacitance and ESR (equivalent series resistance) simultaneously, in seconds. There may some electrolytics in high voltage applications that would require leakage tests under the working voltage but these aren't seen too often. In a test, a 220 uf electroyic 63 wv, with a 500 ohm shunt resistor added, still gave an accurate read of capacitance and ESR. This replaces an ohmmeter, cap meter and ESR meter. I am buying another one. Hope this info is helpful. Yes, for all practical purposes. Incredible, inexpensive device accurately measures R, L and C with high precision.

I bought this kit for our LG flat screen which is 36 inches wide. The kit comes with multiple capacitor sizes. I found that once I opened up the TV not all capacitors were blown (you can tell when they are blown because the top of the capacitor, which is shaped like a small battery, is rounded rather than flat). I replaced about 5 of mine and there were several capacitors in each size in the kit. I would think if you have any LG it would work. I would also think if by off chance you need more capacitors of a certain size you could go to Radio Shack or someplace like that to get more. Watch the video on replacing the, if I can do it anyone can (I am a woman without an ounce of knowledge on electrical components!), my son did help because it was easier to have 2 sets of hands - one to unsolder the old capacitor one side of the board and another to pull gently on the capacitor until it pulls free. Good luck!

I had similair problem with my Samsung. I looked it up on YouTube.com and found that it was blown capacitors. Looked like and easy fix. Search Google and found that Amazon.com sold a capacitor repair kit. Also purchased a soildering iron and fixed it with ease! Under $30!! Good luck.

I found that the ESR function is not reliable testing capacitors while in circuit. It's not very reliable testing capacitors out of circuit.

No, it will not test capacitors in circuit with reliability. When testing in circuit, you do not know whether there are other capacitors in series or parallel with it. It will give you a "Quazi" check, meaning that if it reads your capacitor value correctly, then you now have the problem of telling whether that capacitor is internally ok. This meter will check the value of a capacitor, but it will not check the internal part of a capacitor. There has been times which this meter shows perfect, but when checking with a OHM meter, the capacitor has a internal resistance of 75K instead of infinity. But, if this meter shows a capacitor being off value by a ways, there is a very good chance the capacitor is bad. Remember, there are 3 things that go bad on a capacitor for the most part. 1. Out Value, out of tolerance (This meter will show it). 2. Internal resistance (This meter will show SOME, but not all of this kind of breakdown). 3. Load breakdown (This meter will not show anything on load breakdown).

The capacitors contained in the kit are listed in the item description. If you can't decipher this list, you have no business opening up a TV. You can seriously injure or kill yourself.

The tester will measure your electrolytic cap's capacitance and esr but not leakage. It will test bipolar transistors and identify E B C leads and PNP or NPN, and measure beta gain and E-C forward (on) voltage drop.

I test capacitors on the MfR setting and it is very close to the factory capacitance, it will also pick up leakage voltage down to 1 volt. Best meter after 42 years that I have ever owned.

Some of the capacitors are done; very common of Samsung TV's. This capacitor kit will do the trick. You can tell which capacitors are done by looking at their expanded or burst tops.
