Samsung forum: Samsung LNT-4665F Power up issues- Clicking noise

I am having the exact same issue but the customer service rep. told me my tv was not made in the time frame they are covering. My TV is a few months over two years old. I am very disappointed in my experience with SAMSUNG.

Hi,

My Samsung is also starting to Click on power up (currently takes about 4 clicks, which started about 2 weeks ago)

Was purchased just over 2 years ago (looks like there is a 1 year warranty on it)

I called the Canadian support contact number at 1-800-SAMSUNG and got the standard "your SOL" response. They did mention that they know there's an issue, and that there's currently no fix for it.

Its a different response than what you got; so I'm wondering if you have any updates on how/if your issue was resolved


Thanks

Paul

There are LOTS of URL's concerning these EXACT symptoms on many Samsung TV's at this time. I, personally can provide my hours of research to all of you if it were possible. But the pertinent details are:

1. Power clicking on/off on TV (first intermittent, then longer times before the TV turns on...possible pixels hanging out unnecessarily)
2. Intermittent at first with messed-up pixels shortly thereafter.
3. Diagnosis: Bad capacitors on power supply board
4. Easy to see with several sites that have photo's (bulging/leaking capacitor heads). Search 'http://www.earthinfo.org/samsung-tv-makes-a-strange-clicking-sound/ ' for detailed instruction.

I ordered larger voltage capacitors at Amazon.com. The original circuit voltage is 12V...with 10V Caps.....look for the 16V caps at Amazon.com with the correct microfarad (uf), and temp (high temp is good).


5. With inexpensive electronic tools, a little patience and personal 'Go-ahead' this problem can be resolved for under $20.00. If not brave enough to try, an entire (easily swappable circuit board may be purchased as low as $75.00 - personal research; you may find a lower price). It is normally a power supply board designated as:
BN44-00168b or a similar number which may be cross-referenced).

Anyquestions? I'll be here.

Samsung TV makes a strange clicking sound
My Samsung TV (52″ LCD) started clicking several times before finally switching on after 30 seconds, this relay clicking gradually got worse each time I turned the set on. ( It turns out that this is quite a common problem with Samsung TVs of all sizes). The problem seems to start after the TV is a year or two old (normally outside guarantee) and sounds like a relay clicking on and off. Samsung deny there is a design problem, so I thought rather than spend money on an engineer, I would try and fix the problem myself.

I thought the first place to look for a problem like this is in the power supply.
I unscrewed the back cover of the TV (20 screws)
Removed the metal cover of the power supply (4 screws)

I carefully looked over the power supply looking for anything out of the ordinary, low and behold I could see a few capacitors (the cylindrical shaped components) that had raised tops. These raised tops are caused when the capacitor breaks down and forms hydrogen gas, if left, eventually the capacitors will blow, and hopefully the top will split open and release the gas pressure, if not, they may just explode.

Check out Capacitor Lab for more details on what to look for when a capacitor fails.
I checked out the replacement cost of a new power supply board, I couldnt find the exact power supply online but this company has ones for smallers TV starting at around 160. So I was guessing it would be around 200 for a new one. Ouch, definately time to DIY.
I decided to replace all the capacitors in the power supply, I guessed if some were bad, then probably Samsung use cheap or poorly designed capacitors and at some point the others would go bad too. and replacing all the capacitors wouldnt cost much more .
Each Capacitor has 3 important values
1. The capacitance measured in μF (micro farads) eg (1000μF)
2. Voltage (eg 50V)
3. Temperature (eg 105C)
This particular Power Supply Unit (PSU) has 3 different types.
1000μF 105C at 10V
1000μF 105C at 25V
47uF 105C at 50V
RS Components have a good selection, so I opted to buy from there. It cost about 12 including postage for a 5 pack of each of the capacitors. I took a few photos of the circuit board so I wouldnt forget what I was doing and set to work.
I re-opened the TV, and completely removed the Power Supply Circuit Board, you need to remove several connectors, again, I took some photos just in case I couldnt work out where they all went when putting it back together. I made sure the Power Supply didnt have any residual power stored in the capacitors by unplugging the TV (whilst it was turned on) from the plug. This is very important as messing with a power supply even 30 minutes after it has been turned off can still give you a nasty shock.
I then drew a simple diagram marking the polarity of each capacitor. To remove each capacitor takes a little time, you need to heat each pin using a soldering iron and whilst it is still molten pull or wiggle each leg out in turn. I found it easiest when I used the other leg as a pivot and rotate the capacitor around the fixed leg.
Anyway once removed, you I used the de-solder pump to clean up any solder that was clogging up the hole and then I inserted a new capacitor (checking the values again) and making sure the polarity was same as the one I had just removed. turning the board over, I bent the pins a little, soldered the joints, and snipped off any left over wire.


I put the board back in and hey-presto it all worked beautifully. Job took about 2 hours in total and excluding tools 12 for the components and postage.
[Added 21th May 2009]
If you snap off the solder connector on the PCB when doing this replacement, it is worth noting that you can re-attach your component in another place as long as it is electrically equal. The Red Line in the diagram below shows where an existing component was, this component could then be re-soldered into any of the positions marked in green. But in the case of a capacitor which has + positive and negative legs, you must make sure that the leg is re-attached to the same track, I have marked with a + plus sign which track it must be re-attached too.


Here is a quick summary of my present actions/responses concerning my Samskunk LN-T4665F Television.

The following is an e-mail that I sent today to the Public Relations Departments of both the HDTV and the Corporate Agencies that represent Samsung at this time.

Damage Resulting = Plan to call Samsung this afternoon at a substantial cellphone rate. I will provide follow-up.

Damage Resulting = I called the 800-samsung number and spoke with Whitney. I provided the information as requested by her. She put me on hold, came back within a minute and stated that my model#LN-T4665F is not one of the units that can receive free repair. She would not allow me to speak with her Supervisor/Manager. I will take this to the next level.

I have a LN-T4665F purchased in late January 2008. I've been having this problem, beginning with the clicking and 2 minute eventual start since MARCH 2010. It's getting progressively worse, taking longer to start, small color dots first, then small verticle stripes when restarted along with faintly visible wider verticle 'waves' after restart. My S/N is AJ723CNB03262Z. I have registered this, and other products, with SAMSUNG and would like to have my technical issues addressed, please.

Thanks,

Just today started this "clicking" when turn power on. On cold TV takes about 3 mins of "clicking" to finally power on to see picture.
I got it as a gift in August 2008 and today June 26, 2010. Not even 2 years!!! What a pile of )@(*#$&^&! this Samsung is. I will call tomorrow 1-800-SAMSUNG here in Toronto to see if they can fix it but I dont have receipt, only documentation and box original. I cannot beleive so many people have same problem starting with earlier models and Samsung not fixed this. No respect for customers, as old saying - they are cutting the branch they are sitting on.

I too am a victim of Samsung capacitor problem. I purchased the LN-T4665F on Aug 30, 2007. My TV started this clicking sound when trying to power-up about three months ago. Now it takes about three clicking on/off before the TV turn on. I decided to surf the web to see if I was the lone victim...no, I am not. Thanks for this web and a lot of helpful good hearted folks. I called Samsung last night and they told me my TV is not on the list for repair and gave me a local electrical company to call. I called them today and their charge to drive to my house is $175.00 plus whatever it will cost me to repair the TV. So, this weekend my home project will be to repair the set myself. I've no electrical experience but willing to take on this problem. I'll post later how I made out with the repair. I too, will never buy another Samsung product. I am thinking of Sony in the future for television. Am I ticked off with Samsung? YES.

I replace three capacitors 10V with the 35V today 7/30/2010. My TV is working great now.

Yes, it was easy repair. There are many places online that folks have provided good info. The site I used was on YouTube, go to this guy website and he has a video on replacing the capacitors: milosmommy's Channel.
Also, go to this site: (http://www.earthinfo.org/samsung-tv-makes-a-strange-clicking-sound/comment-page-14) and there is a diagram on replacing the capacitors and many tracks on the caps problems. The hardest part is de-soldering the old caps out- just make sure you replace them with 1000uf 16v or 1000uf25v, I use 1000uf 35v. It you replace them with the 1000uf 10v you will have the same problem in 2.5 years. I use the easy process I found on one of the track:

1. Laid the TV Face down on a padded Table and removed all the screws. The top just Pops off.
2. There is a protective cover over the circuit board. unscrew and pull off.
3. Unhook all of the wire attachments that connect the board to the rest of the TV and unscrew the 6 screws that hold the board down and pull it out.
4. There were 3 bulging capacitors on the top right. you can take the whole board into radio shack and they will tell you what replacements to buy. (I Upgraded to 35v to prevent future problems). The caps are $1.59 at Radio Shack. You will need the capacitors, a soldering iron, solder, and a 6 inch long nose pliers. I spent about $35.00 and two hours of my time and my TV was working as new again.
5. de-soldered the backs of the three capacitors and clipped the leads.
6. Put the new capacitors in their place (watch for the polarity. bent the leads to the side to hold them tight and soldered them down.

Note : to those attempting this, MAKE SURE YOU CHECK THE POLARITY OF THE NEW CAPACITORS YOU PUT IN. There is a POSITIVE and NEGATIVE side to a capacitor ( indicated by a white line across the length ) and on the main board where the capacitor goes, youll find half of the circle where the original capacitor rested painted with diagonal lines. The NEGATIVE side of the new capacitor goes there. Make sure to check for that.

Good luck and let me know how you made out.

ou are welcome. I am sorry you are still having a problem. Try googling your problem to see if anyone out there are having the same problem as well.

Took your advice and pulled the power supply board and sure enough found 3 bad capacitors and one that was starting to bulge. Radio Shack had the replacements (35v). Removed old and soldered new ones in (paying attention to polarity). My LN-T4066F is now up and running again good as new. Thanks so much for the tip.

2 years old....Started clicking 2mos. ago....Put up with it and then I decided to get it fixed. Called Samsung and they stated a Tech. would come out ......free of charge...in 1 to 2 days.....Now that's pretty good service. Should not have happened in the 1st place, but I will take a free fix.

I have an LN-T4066F that is 3 years old in a little over a month. I have the exact same issue as you guys and many others are having where the TV clicks for a while before starting up and eventually instead of starting up it just displays a lot of vertical lines(sometimes black and white, other times multiple colors) or a solid colors(RED, PINK, GREEN, ETC.) The only TV or remote button that worked was ON/OFF when this happened. The last time it was able to start up it looked like it had a bunch of dead pixels but they weren't, some pixels just hadn't changed from when the menu/source icon was there and they were fine the next time I started it up(except for displaying those vertical lines). I called Samsung, told them my problem and they said Samsung is allowing a one time repair free of charge for TVs with this problem. They never asked if the TV was registered, when or where I bought it or anything other than my number and address. So please, call Samsung, they got me taken care of in 5 minutes and it didn't involve any arguing or yelling or anything(I work retail so I know what it's like to deal with people(babies) who think the louder they yell the more likely they'll get helped.)

Does this mean that phone reps for Samsung have the DISCRETION to allow or deny a fixing of this problem? Because I got a "no" from SAMSUNG today! What is the best way to approach SAMSUNG to get a uniform response?
Thanks!

The same thing is happening with my Samsung LNT 4665 (46") bought in Oct. 2007 from BestBuy in western Canada. I called 1-800-SAMSUNG and was told that this was NOT a known or recognized problem as far as Samsung is concerned, and therefore not covered by any sort of warranty. I was given a Samsung-authorized repair service phone number in my area. The service centre I called was in South Carolina, so I know it's not just a Canadian Samsung Service Centre response.
I told the woman at Samsung that there were lots of people who have posted online who are having the same problem. She said that she had never heard of the problem occurring before.
So, I called the repair shop. I don't want to go digging around in the guts of that thing, not for paying 2400 bucks for it plus taxes.
I think SAMSUNG should pony-up for whatever the repairs cost if it is a known capacitor problem.
