Can capacitors be bad even though they are not swollen or leaking? I'm unable to see the caps 'cause LG put some sort of caulk across them.

I am not sure but if your TV is taking a long time to come on, some are probably bad. I re placed all of them in the kit even if they were not swollen. I hope this helps.

Mine were only minimally swollen, but replacing them made our television usable again. Before replacement it was a 10 to 15 minute process to get TV powered up, now just 10 to 15 seconds.

All the capacitors on my LG power board were clearly (and normally) scored with the X which is designed to act as an indicator of a bad capacitor by popping up. There are a bunch of youtube videos showing this. If you are correctly looking at the appropriate capacitors you would be able to see some cracked/raised surface on the top of the defective ones. The kit worked perfectly for me with a large number and assortment of capacitors and everything necessary other than a soldering iron. I bought a solder sucker at radio shack for a few dollars that worked far better than the solder wick provided. I can't begin to imagine LG caulking over capacitors to make it impossible to easily find a defective one.

It just might I replace all the bloated up capacitors basically no more noice and taking long on turning on. But if it has lines going up and down thats a picture board problem. Hope this helps.

There's nothing defective about your unit check the second comment for contacts. I own several of these and the internal component isnt lined up correctly. Best of Luck. Stick with it. The reward is worth the trouble.

No. I pulled mine apart because of the same issue and found it was the back lighting (shine a flashlight when it is on and you will see your screen still works, just no backlight). The lower CCFL wires for mine had a bunch of unidentifiable crystal like corrosion which might be due to bad SIC insulation but my CCFLs worked fine. I cleaned the corrosion and tested good. Prior to that I swapped out all of my electrolytic capacitors on the supply board. Still nothing. Considering getting a new one to match my good one or buy two new monitors and move on.....not sure yet.

I'm not sure but there isn't supposed to be a lot of water on the inside. If water continually seems to be on the speakers one of them might be leaking. If not then you shouldn't have any problems with it hope this helped!

It would tell you if it is charging, but not if it was leaking. I use it for basic testing, and it is great for that, but would not rely on it for testing capacitors.

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.

You are correct in not pleasing everyone. Yes, on following the manufacture's instructions. The leaks come from the screw on cap getting loose while the unit grinds down the contents - in reverse of how you tightened it in the first place. There is a hole in the power unit so the liquid drains out but it is very messy. :)

There are some electrolytic capacitors. They are polarized. The rest of the assortment are ceramic or Mylar, or whatever and they are not polarized.

I have the same problem and I think it's the power board. the capacitors need to be replaced. Look it up on YouTube, how to replace if you want to do it yourself, amazon also sells the kit to fix the capacitors yourself. And yes I think RCA is very bad.

I had the same problem, still under warranty, and the company refused to fix them. Do not send them back to B&O (who wanted $50 to fix mine). Go to a local electronics repair shop. I did that and had them fixed for $5.

I am not sure - suggest while you have it open to see if the capacitors are bulging - if they are, then I would replace them. You will also be able to confirm whether the specific capacitors in this kit are the exact ones you need.

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.

Above and to the right of the display board (on the main board), look for a black capacitor (black round disk). I've had that blow twice already, and just replacing that fixes the system.

You have to be more specific about your problem. Is it plugged in correctly? Is there any visible damage? Did they ever work, or are they new?

It will work if the capacitors are blown but sometimes that isn't the problem. Check for bulge in the capacitors.

There are no guarantees. In my case mine was doing exactly this and replacing the capacitors did not fix it. I am glad I did replace them though as a step in the full repair.
