Product Description

This repair kit supplies the capacitors needed to repair the power supply board inside a Samsung LN46A550, LCD TV. This repair kit is for the power supply board pictured above. Please verify that the power supply board inside your LCD monitor or TV matches this power supply board before ordering!

PLEASE NOTE: You are not purchasing a power supply board, only the capacitors needed to repair it!

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors

- Flickering screen

- Screen image disappears after several seconds

- Dim screen

- Slow start

- Power LED on, but no picture

- Unusual colors and/or lines

The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.

If they appear bulged on top, then they need to be replaced.

New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.

We only use the highest quality Panasonic, Nichicon and Rubycon capacitors in our repair kits.

This Samsung LN46A550, LCD TV repair kit contains 8 capacitors needed to repair the power supply board inside your Samsung LN46A550, LCD TV. This kit does not include the large 400-450v capacitor, that capacitor may be purchased separately.

We only use high quality capacitors manufactured by Panasonic, Nichicon and Rubycon in our kits. We do not use CapXon capacitors.

If we don't have a kit for your LCD monitor or TV, we will gladly assemble one.

I purchased a Samsung LN46A550 in early summer 2008. Around 2011 it started to have the "click of death" and after a few days, wouldn't come on at all. Some research revealed that this set suffered from capacitor plague. Since I had an extended warranty, I filed a claim. Two days later a repairman showed up, replaced two bulging caps on the power board, and the TV was resurrected.

In January 2014 the problem recurred. It would click four or five times until it finally came on. Rats. I really like the set; it gets heavy use and I have always enjoyed its picture quality. The thought of replacing it didn't please me, so we left it on 24 hours a day while I looked for a repair kit and found this. It arrived in a few days.

Upon pulling the power board out of the television, I found that the two capacitors replaced a few years ago were not bulged, but three more were. I replaced both 25V 820's and both 25V 470's, and voila! One click and the set came on. I didn't replace the 10V 1000's because they were not showing distress and had been previously replaced under extended warranty. Similarly, I didn't use the 50V 47's because they were also not showing distress. But I kept them just in case.

I have little experience soldering and I had never desoldered anything before this repair. I own a cheap soldering iron that wasn't very effective for desoldering. In the middle of this repair I went to a home improvement retailer and bought a 100/140W iron that made the work very easy. Pull the trigger and it gets smokin' hot in a few seconds, and it got sufficiently hot that the copper desoldering braid worked really well.

I've had my LN46A550 for nearly 7 years and it has seen very heavy use, serving my household well. All things considered, a great TV, overall. Recently, the set started experiencing the infamous click of death, where the set would take increasing amounts of time to turn on. It was about to give up the ghost. While I could have purchased capacitors and desoldering wick piecemeal, I had never done any kind of repair like this before and wanted to minimize the room for error. This kit has everything needed to repair the faulty capacitors in these TVs, with the exception of the soldering iron. I only had two bad caps, which were easy enough to replace, with the help of an easy to follow youtube vid. (One can just search YT for LN46A550.)

I'm keeping the spare capacitors in case any others go bad. Fixing the capacitors on this TV is a very easy, quick repair for anyone who has a minimum experience of at least building a computer/minor technical know-how.

My Samsung was doing the click of death thing, so after searching I eventually came across this kit. I did not see any capacitors with signs of failure but I used all of them in the kit. My TV is working again and I'm a happy man.

I did have an issue receiving my order but it appears our USPS lost my first order. I sent an email asking "Where's my Stuff?" I received an email response very quickly and they sent me another which I received a few days later.

Maybe it's a little expensive for capacitors, but it was definitely worth the convenience of a one stop shop.

Well, Shazaamm! it worked! The 46" TV developed the "clicking" at power on symptom (at about 8 years old). It did turn on, but it seemed clear that it would soon not even turn on. I bought this kit, looked at some videos (there are many, plus the ones referred to in the instructions.) The whole thing took maybe 40 minutes, but that was because we were calling my five year old grandson over occasionally to show him some interesting parts of it. Two caps were bulged on top; we replaced only those two, reassembled, and it worked just fine. This is a good kit in that it had several more caps; apparently the same ones are not always the problem. It was a really nice solution in that the TV still delivers the like-new picture, which after 8 years I still find stunningly good.

My TV had completely died except for a little clicking and flash of the screen. After doing some research I ended up opening up the TV and finding the tops of 4 or 5 capacitors were bulging out (bad).

If you are familiar with soldering this is really pretty straight forward. It's all through hole soldering and no multi layer boards here.

I used a solder iron and solder sucker not the wire wick that was supplied.

Protip: I desoldered one at a time and refitted with the proper size. Only to bend their leads and triple check polarity NOT solder yet. Once all were placed in the holes and I rechecked polarity 10x did I solder and cut all the leads.

This worked as advertised-- all you need in addition to the kit is a soldering iron and a little skill using it. I replaced only two capacitors that were obviously bad (the 820uF ones) and voila! IT TURNED ON. No more clicking and cycling on/off forever. I'm saving the other capacitors for future, inevitable, failures. It may be possible to get only the components you need for cheaper elsewhere, but from what I found the price difference was not huge, and this kit ensures you get what you need. Recommended.
