Samsung forum: LN-S4041D takes a long time to turn on

jackamy,

I wish I had a solution, but I don't. It may be that your power supply needs to be replaced, but outside of being able to actually look at it, I'm really unable to give a thorough diagnosis.

Yeah It's really frustrating for sure. Not sure what I will do. I may and swap out the power source.. Good luck

Yes It starting a few weeks ago and got progressivly worse. Now it will not turn on at all. The tv has been flawless up until now.
I tried using a different power cord and no luck. I have too much invested in it as I bought it 2.5 year ago for a pretty penny. I may have to take it to a local repair shop to see if they can fix it.
Good luck with yours

I have the same problem,
my tv is just over 3 yrs and never had a problem
and recently it took longer to turn on with clicking sounds
and got worse till now it doesnt turn on at all
Samsung is crap and I will never buy their products again

Our Samsung model # LN-T405 HA would click up to 30 minutes or more before finally turning on. Called a repairman in Tallahassee, FL. He said it would take $185 to $300 and 8 days to fix it. Read posts at several forums and did the fix. Laid the TV face down, undid all the screws on the back, seperated the back and removed it. The power board had 7 screws, unpluged the cables running to it and removed it. The 2 big (physically big) capacitors were bulging at the top. Interesting to note they were marked only 10 volt and all the smaller ones were marked 25 volt! Turned the board over, heated the solder joints (small soldering iron) and removed them. They read 2200uF, 105 degrees centigrade,10 volt. Radio Shack's radial capacitors go no higher than 1000 uF. Could not find a replacement anywhere in Tallahassee. Googled several electrical component sores. Allied Electronics in Largo FL had lots of them in 25 volt! Their part # is 852-7038. It's a bit larger but fits fine. Their phone # is (800)433-5700. Had them overnight 2 to me. They sent 3, one for a backup. These things are cheap at about 80 cents a piece, the third one they included free. Put them in, an easy fix. Plugged in all power cables, put the back on, handed the remote to the wife (she's a big football fan and it was mid-season), she hit the power button, one click and the TV came on! I got a hug and didn't have to wash dishes that night. No problems since.

How do I know what needs to be changed?

Hi, I just called Allied Electronics as you suggested, and spoke to Christy (Christie?) about the part. She noted that they are only about a buck a piece and said she can just sample them to me, meaning that in a couple of days I am going to get four of them for free! She was obviously extremely helpful and nice, so definitely hit these folks up if you need to repair your Samsung TV!

Thank you so much, my brother in law and I followed your instrutions and in 30 minutes ( due to the AL,,TX game 2 differ tv's) we were done. So appreciate your help.

I have been reading about all of the people who have been able to fix their TVs and it sounds great, I even watched the Youtube video. Only I know there is no way for me to take apart the TV and sodder a part into it. So, my son and I have left the tv on. At night while we sleep we mute it. For all you people who know how to fix your TVs Bravo. If you know where we could find some who knows how to sodder and maybe pay them to help us, I can not afford a pro at this time. Please let me know. Thanks

If I am reading your post correctly I can replace that whole square thingy I saw in the youtube video? That would seem more likely for me. I will look up the cost for the part and then ask my oldest son's friend who is the "jack of all trades" to come over and help me. I appreciate you taking the time to respond.

Cheers

I hate people like this. Blast someone for wasting energy when I know I can find 100 things you do that waste more. Once cycle of your dryer takes more energy than that tv left on for a month. Unless you live in the woods, make a fire every night, hunt your own food, walk or bike everywhere, and use no electricity then you are using something that is not necessary and is wasteful.

There are hundreds of people having problems with the four bad capacitors on Samsungs power supply for these models. They refuse to recognize this as a manufacturers defect, because it would cost them much $ for a recall. So they say...well its out of warranty so we did our part. Fact is...with the low cost of Samsung LCD TVs, you NEED to pay for the extra warranty and include this in the price of the tv. Samsungs are notorious for bad power supply problems. Internet search for yourself. Samsung bad power supply.

There is video on youtube on how to fix this. My Samsung LN-T4061F had two bad capacitors on the power supply board. It cost me less than $30 to fix. I ordered the solder, soldering iron, and 2200 uf 16v (the ones on the board were 10v) for under $30 including the $10 shipping cost. It's an easy fix and it's sad Samsung won't recognize the defective capacitors. It's easy to figure out which ones are bad. They have an X or + on the top. If it isn't flat it's bad. I replaced them and my tv turned on like I just bought it without the clicking for 10 minutes.

Hi. Would you be able to let me know where you ordered the capacitor from? If so, would you have a model # from the place you did? I would so greatly appreciate it. Also, is your tv still working great now?

Had the same issue as everyone else. Slow to turn on and the time it took to power up got longer and longer until it finally didnt turn on anymore. Had the capacitors replaced but that did not fix the issue. Have Great sound but still no image. Its a dark screen. Had a tech come out and look at the set. He then called to ask someone else what they thought it might be. He said it seems like the display/screen assembly. That an $800 part not including labor to put it in. When asked if the board could be bad, he said No because theres good audio. Tv is just 2 years old and is now a $2000 paperweight.
Model # LNT4669/XAA Will NEVER buy Samsung product again. They dont stand behind their product. What ever happened to customer service and the customer is always right? Guess that went out the window. Well I will be sure to tell everyone I know what a crappy company Samsung is and to not buy their product.
