Samsung S4051D HDTV Problem. Please help!
by MSmith2004 - 6/11/09 2:02 PMHoping someone can help me with my current issue. I had the typical power supply problem where the tv would click and act like it was turning on/off. Not sure if it was my fiddling around with it or what, but a few days later it acts like it's not getting power at all. I k now the plug works as the brown and blue wires are registering 120v AC to the board. Of course, I checked the forums and heard the initial problem is caused by 4 bulging caps, which I was able to replace, but this was only after it stopped turning on period. Been trying to test different components and can't really put my finger on it. I noticed the 16 conductor ribbon cable looks like its damaged. Does power go from the main power board to the board on the right or vice versa, cause i'm only registering like .1v dc on the leads to where the ribbon cable plugs in on the board. Anyone have any idea which component may be causing this? Please help. Thanks in advance.

Turning on issue
by BLBakersfield - 6/15/09 7:32 AM In reply to: Samsung S4051D HDTV Problem. Please help! by MSmith2004I too am haveing a similar issue with my 46" Samsung which is only 18 months old. First time when turning on the TV after it has been off for the evening, it clicks on and off for about ten minutes then turns on. Any ideas what this might be before I look for another TV/repair person?
fixed it!
by MSmith2004 - 6/16/09 9:58 PM In reply to: Turning on issue by BLBakersfieldI figured out what was wrong. Apparently it is common and it was the capacitors. Easy fix. cost like 4 bucks max. if anyone else has this problem where it clicks and turns on and off let me know and i'll be glad to help.
How did you fix it?
by BLBakersfield - 6/17/09 3:04 AM In reply to: fixed it! by MSmith2004So it was the capacitors, can you let me know how the fix is done and what part numbers or specs of the parts?
Thanks

by MSmith2004 - 6/18/09 9:33 AM In reply to: How did you fix it? by BLBakersfieldThe capacitors I got were from radio shack. part # 272-1032. The capacitors that were bad were the ones that were bulging at the top. They were four 10v 1000 microfarad caps. I replaced them with 25v 1000 microfarad caps bought from radio shack. They are slightly bigger, but fit just fine. If you were to take the back panel off the tv, you would see two main boards. The power supply is the one on the left. Once you are looking at the power supply board, the problem capacitors are in the upper-right corner. Just to the left of where you see a ribbon cable connecting the two boards. Like I said, you should see the four capacitors bulging at the top. To replace them you have to de-solder the caps by unscrewing the board from the tv. then replace them with the new ones. There is usually 4 that are bad. I believe they cost about a dollar each. If you have never soldered before I can pretty much let you know what to do. It is fairly simple/easy for this fix. Just have to make sure you put the capacitors in the right
Samsung HDTV same problem!

Thx.
How to solder and de-solder.
by MSmith2004 - 7/26/09 2:27 PM In reply to: Samsung HDTV same problem! by Binx66I already had a soldering iron and some solder. It's an extremely easy process. Get a 25w soldering iron, a desoldering bulb, and some solder. You have to remove the 6 screws or so and remove the cables that are connected to it so you can access the underside of the psu. Don't worry, it's extremely easy to do and shouldn't worry about damaging anything. Each capacitor has 2 prongs that stick out the bottom that go through the board and are soldered to the other side. Place the tip of the heated soldering iron on the pad of solder which is connected to one of the prongs of the capacitor on the underside of the board. In a few seconds, the solder should melt completely. Keep the iron on the pad of solder and use the desoldering bulb, which is just a little suction device, to suck up the melted solder. Repeat this for every prong. Then you may remove the busted caps. Now, when you place the new caps in, not that they have to go in a certain way as capacitors are polarized. The capacitors are marked on their negative polarity, usually with an arrow down the side of it pointing to the negative prong. The psu board is also marked to tell you where to put that side in. Once you put the prongs through the hole of the board, bend them 45 degrees just so they don't fall back through the board as it will be upside down when you solder it. Touch the iron to the prong of the capacitor and to the metal ring which goes around the hole of whichever prong you are soldering. Apply a small amount of solder until the hole fills up and the prong is attached to the board. It should take about 5-10 seconds to dry, in which you don't want to move the prong as this could cause a weak electrical connection. Do this for every prong on every capacitor. After this plug in the cables and screw the board back on and you should be set to go. Hope that was easy enough to understand, let me know if u need anything else.

Can you use the following link to a series of photos of the power supply for the 4051D to show me what you're talking about? I don't want to drop $300 to get this fixed at a TV shop.

Bad link
by friday04 - 7/26/09 2:11 PM In reply to: parts by MSmith2004Whoops, CNet didn't like something about that link. It's a link to a site called discount merchant and they starred out that portion of the link. I promise it's not a malicious link. Here's a shortened version.

Caps
by MSmith2004 - 7/26/09 2:38 PM In reply to: Bad link by friday04I looked at the board and it's not the correct one for the s4051d. I was trying to find a pic and i guess there are s4051ds models as well as s4051dx that all have similar but different psu boards. Have you opened up your tv to see if it's a match? Either way, the capacitors in question, upon opening your tv and looking at the psu board, are in the upper-right hand corner. They are right next to a ribbon cable which connects the psu board to the board to the right of it. They are 4 black ones. I noticed mine were bad as the tops of the capacitors were bulging and some even had black/brown goo leaking out.
Here is the link to a picture of a nearly identical capacitor. Only the black part on top is sticking above the board. The prongs go through the board, are soldered and cut to the board.

That is what you will want to look for. Marked on the side is 10v and the symbol for 1000 microfarads which looks pretty much like 1000uF. If you haven't already, open your tv. Just lay it, screen side down, on a flat, preferably carpeted floor, and remove all the screws around the edges. There is also one on the part where you plug your video/coaxial/hdmi cables in, which i didn't notice at first and made me wonder why the tv wasn't opening. The psu board is the one on the left, and in the upper right hand corner you will notice the 4 capacitors that look like the one above. They are all next to eachother and, more than likely, will have bulges at the top. If you still can't seem to identify, let me know and I can open my tv and take a picture with my phone for you.
Replaced bad Capacitors and still a no go
by jonclinton - 9/11/09 8:00 PM In reply to: Samsung S4051D HDTV Problem. Please help! by MSmith2004My TV was doing all the things everyone else's tv was doing...delayed turn on clicking noise and then nothing. I replaced the 4 capacitors cm806,812,817 and etc with 1000 uf 25v from radio shack. I made sure all of them were in correctly and completed the soldering. Turned the TV on and the sound was the normal turn on sound but it acted like it was trying to come on and actually did for 1 sec then turned off. I am stumped and need some help?
Thanks
Jon
Fixed it
by jonclinton - 9/12/09 12:44 PM In reply to: Replaced bad Capacitors and still a no go by jonclintonEverything I did by replacing the capacitors worked but when I plugged the TV just into a outlet nothing happen. It wasnt until when I hooked everything up that it worked. Dont know why but it works now and I am happy to be watching football!

jonclinton,
Just to answer your question, there is usually a kill-switch when the housing is off the unit.
