    Hi Again Tom
    Capacitor received was from Digikeys - you are right I typed in the wrong number
    Should have read:
    399-5925-ND

      Did you get the right part? Is your tv working now?

          My LG same model is doing the same thing. I bought the same cap and installed it. It didn't work. Anyone have any ideas to try next? Some kind of meaningful troubleshooting?

            One more thing. This happened 5 months after i purchased it. It was under warranty and covered the repair. Here i am again 1 year later, same issue.

              Thanks for the information in this thread! Replaced the C802 capacitor on my LG 50PA4500 that would immediately shut down after powering it on and it works again!

                I have a 60PA5500 and I am having some issues as well.

                When I first plug it in, it makes a click noise (not sure if this is normal or not).

                Then when I try to turn it on, it clicks once like it's turning on, then it immediately clicks off.

                Interestingly enough, if I leave it unplugged for a few minutes or an hour, it'll start working again perfectly. I can turn it on and off as much as I want and use it all day. It'll click when I turn it on and when I turn it off.

                But when I shut it off for the night and come back in the morning, it goes back to clicking off as soon as I turn it on.

                This sounds like a bad capacitor to me but upon visual inspection of the power board and all other boards, all the electrolytic and film capacitors look fine to me.

                Could this be a bad Y-SUS or Z-SUS or mainboard instead?

                Or could it be the C802 capacitor that a lot of people with the 50PA5500 have had success with replacing? The power board between the the 60PA5500 and 55PA5500 are a little different but the 60PA5500 does have a C802 near the top in a similar location.

                If it does sound like the capacitor, how do I know which one to order? It might be different than the 50PA5500 one.

                Any input here would be greatly appreciated.

                Thanks

                    Sorry I'm new here. I kind of realized I should start another so I did last night.

                      Replacing the capacitor at 802 with the one provided on the digikey link fixed my 50PA5500. Many thanks to everyone involved in finding the solution. The old capacitor looked perfect and was black. The new one from digikey was slightly smaller and blue.
                      MyLG was a little over 4 years old.
                      Thanks!!!

                        Is there any way to determine if C802 is bad? Does it puff out like a normal cylinder shaped cap? My 50PA5500 is exhibiting similar issues that others have described in this thread, try to turn on, clicks, turns off. No picture/sound, just red power light turns off and then turns back on after the click when trying to power up the set.

                        Just wondering if there is any other way to test the TV out, or should I just order a new C802 capacitor?

                          Test the capacitance with your meter.

                            Is there a thread somewhere that describes how to do that? I have a decent multimeter, but I don't know the proper procedure on how to test capacitance.

                              What meter do you have?

                              Does your meter have a symbol like 13 on this attached picture?

                                Hello, i have some issues with my laptop Lenovo Y700-17ISK (motherboard BY511 NM-A541), it started when i turn on the laptop, but the lcd wont turn on, i then connected it via hdmi to tv and screen was ok. So i thought maybe lcd stripe is faulty, i removed the bottom cover, disconnected main battery, reset the cmos by disconnecting battery for 1 min, then slighty move the lcd stripe. Conncted power supply and tuned on my laptop, the lcd turn on, it started to load os, then it turn off, after a second it turn on, then after like 3 seconds turn off again, and so on. Removed power supply, waited...

                                Hi,
                                I've been living in the same apartment for about 5 years now, and moved into it with my old Samsung plasma TV (PS51F5500).
                                Ever since we've moved in, we would sometimes see strange power-cycling behavior. For example:
                                • TV would randomly turn off then back on.
                                • TV would turn off and the LED light would blink for a while (over a minute sometimes) until eventually it went back to a regular off state and could be turned on
                                • Sometimes it would require disconnecting the mains cord from the TV, waiting several minutes, then putting it back in and turning the TV back on. This had limited

                                This happened last Saturday and today I finally had time this morning before I went to work to replace two non brand capacitors

                                I will let you be the judge weather or not these are bad or not according to the blue ESR meter that I am using

                                I was watching TV when there was a huge lighting strike nearby my house that shook the house. When that happened, the picture on the TV froze and the TV wouldn't turn off except by pulling the power cable. Now if you plug in the TV, it seems to turn on (it makes the turn on "clikcs" it always does, the red power light comes on but there is no picture, although I can see the back light around the edges. And the TV doesn't respond to the power button on the remote to turn off, and doesn't respond to the manual power button on the front...
