TV won't turn on

Nov 22, 2008 4:21AM PST

I have the Samsung FP-T5084 50" Plasma tv. I went to turn it on the other day, and it wouldn't turn on. No clicking. No red power indicator light. Nothing. It was plugged into a power strip with other components, and they all work fine. I unplugged it for a while and then plugged it into a different outlet on the power bar, but it still won't turn on.

After reading and watching some youtube video, I decided to give the capacitor thing a whirl...I won't pay any service tech to get screwed....bought the capacitors at digikey,com got the 105c with 2200uf at 25v...the originals were 10v...was told it's good to up the volts

Wish I had check this site before buying Samsung 50" Plasma
Dec 17, 2011 11:01AM PST

Well hind sight is always better than no sight. I wished I had posted the question about the Samsung 50" Plasma. FPt5084. Great picture for a year and then it blew a fuse so I replaced the fuse and it ran for another 8 months, right after warranty ran out and now it doesn't turn on and the power light blinks. So I am ordering the new CAPS tonight. I removed the board and found 4 caps domed out. Also found one over on another board off to the left facing the back of the tv. Only one there and it is lightly domed. But its not on the power board so will do them first.

Thanks all for your venting and TECH SUPPORT is a poor choice of words. Samsung should have stepped up to the plate two years ago when this first started to show up and then have the same issue with 2010 models is plain greet at the corperate level. No wonder we have OCUPPIERS all over. VENT VENT VENT.

Samsung Plasma died
Oct 22, 2014 2:05AM PDT

We've already replaced the power board because the capacitors looked fine, no bulging, nothing. Could they be dead and look totally fine? Nothing looks burned out. We've changed the cord, the plug, the power board, still nothing. No power at all. Just like some others, ours just went off one night and never came back on. Brand new. Bought it in January.

Samsung turn on problem
Dec 28, 2009 9:36AM PST

Samsung has a major problem with their power supply. They have 3 capacitors (1000uF/10V) that blow up and die. This happens just AFTER the warranty! Their customer service denies this but if you run a search on youtube ?Samsung power supply? there are a few videos that shows you how to do the repair step by step. I used this video and fixed mine. I called their customer service before fixing my TV and they denied there is such a known problem (what a joke) and offered to set up a service call at my expense. Look at the number of people views for all these repair videos and it is above few hundred thousand. Amazing number for a problem that doesn?t exist!! Samsung should be ashamed to continue using these caps even after they found out about the problem. The difference in the cost would have been about 20C. I wish some one would take a class action against them.

Jan 4, 2010 6:38PM PST

I've only had the TV for little over a year. This seems to be a reoccurring problem with very many people could it be a faulty part. If so could I get My TV fixed for free.

50" Plasma won't turn on.
Feb 25, 2010 5:31AM PST

I also seem to be having the same problem as many of the others have had. My tv was doing the click noise for about two weeks when I finally unplugged it as the manual said to somewhat reset itself and it appeared to fix the problem. Recently I went on vacation for a week and came back to my tv doing absolutely nothing. I can only gather that it is the same problem as everyone else, having tried different outlets and re-plugging in the power cord to the back of the tv. With that being said I have had my tv for about a year and a half, is there any hope of samsung fixing this product for me without charge or am I just screwed. I also have a 32" LCD samsung I purchased 2 months ago. Are there any problems with these models having the same problem as the plasma?
I must say that I am a consumer that believes in buying an American product and if that is hard to do (as the case with tv's it seems) I generally try to find products with good quality. This is what I believed I was doing when I purchased a Samsung but it appears that its just another mass produced piece of crap for overseas. Having read the previous post as well as my own experience I would certainly hope that the manufacturer would do something about this wide spread problem, however would still not recommend or buy another samsung.

L-NT4045 Not turning on
Feb 2, 2009 2:44AM PST

My 40" LCD just began clicking several times when turning on after Tech replaced "the panel" last week. This morning it keeps clicking and will not turn on at all. I've swapped to a known working power outlet, but no change. I can unplug it for 10 mins, plug it in, and it just starts clicking before i use the power button.

Is any part of the power button or power supply replaced as part of "the panel"? My room mate watched the tech replace the panel and says that he replaced just about everything but the plastic outter part.

I called NISI this morning, but they didn't have an answer on "what they're going to do about it" until the tech gets back to the office.

I'm a little upset now because i reported the problem with the picture on 12/31/08 and it took them alsmost a month to fix that.. Now, its COMPLETELY inoperable. I would think NISI would do something RIGHT AWAY about it. This is a major purchase, its only been a year and is the only TV i have.

Thanks for any input!

L-NT4045 Not Turning on
Feb 2, 2009 12:05PM PST

I didn't watch him fix my TV, so I don't really know what all he changed. He just said it was the Power Supply, and he had to change a Board. When my TV went out, it didn't even make a clicking noise. Not sure what your problem could be. Best of luck!

Call NISI....
Feb 4, 2009 6:10AM PST


I'm sorry to hear you're having these issues and that it wasn't fixed the first time.

I would call back NISI and see what they say about fixing it, and in a relatively quicker manner than what you've experienced so far.

Keep me posted.

Samsung HD Tech-

Thanks for responding, but-

NISI is COMPLETELY USELESS!!! I thought HP support was bad, lol. This is the worst of any electronic item I'VE EVER PURCHASED! I don't believe I'll be purchasing another Samsung item with this kind of service.

NISI NEVER CALLED BACK. I called them, Samsung called them - no answer. That afternoon, I got the VM and left a VM.. No call back. Tuesday morning I called and they sent someone out that afternoon. (I'm glad i have a room mate that's off during Tues and Weds. People have to be millionaires to be able to afford taking off all these days for Samsung!) When the tech came out, he turned the TV on and off a several times (and it worked) and said if it happens again, give him a call.

Well, we never touch it after that on Tuesday (yesterday). I turned it off last night with the remote. I turned it on this morning with the remote and .. FOREVER. NOT TURNING ON.

We call this morning and they said they would come out at noon. they advised to keep it plugged in (letting it click and click over and over) until the tech gets there... TECH NEVER SHOWS!!! We call about 3 and they say that he's too backed up and won't be able to make it today (ok, when i have stuff to do, its called "overtime"!). Then they say that they don't have any openings for appointments for the rest of the week and only have Feb 11th open.

SO- I guess i won't be having my guests over THIS F'N WEEKEND! THIS IS COMPLETELY INEXCUSABLE! THIS IS THE WORST SERVICE I'VE HAD WITH ANY ELECTRONIC ITEM EVER PURCHASED- EVER! When i call Samsung, they just try to pass the buck to NISI. NISI is legally acting on behalf of Samsung, so I would think they would give a crap!

SAMSUNG SUCKS. I should've just purchased a Sanyo! I've had several of those for YEARS and NEVER EVER had an issue!

HD Samsung_tech:

Thanks for your assistance. The technician from GEMS Electronics (Dallas) called on Saturday morning. he asked what the problem was and after explaining, he said he would order the parts and be there on Wednesday or Thursday. He actually showed up early wednesday and replaced the part and we're as good as new. I had some blown capacitors on one of my boards. He says it just happens. He also was wondering why the previous tech came out and didn't know what the issue was. GEMS tech knew just over the phone.

It REALLY matters who you guys send out to work on your TV's. Samsung can say its the tech company that's the issue all day long, but it comes down to "Will I buy another Samsung product, if this is what happens when something goes wrong". I have liked samsung, but really have a bad taste in my mouth from them now. :-\

I would suggest anyone at minimum plugging their TV in a power conditioner and major surge surpressor.

If you know electronics, you can solder your own capacitors. These TV's are easier than PCs to work on. You can also order the parts pretty cheaply and replace them VERY easily.

Hope this helps someone.

Thanks for taking a moment to post your feedback.

First of all, I'm glad the issue was fixed.

Second, I also agree that it matters on the technician side. Obviously, we try to align ourselves with local, interested and professional technicians. We do our best to deliver top notch service when something goes wrong. I for one can attest that no service issue on ANYTHING is a fun process, but it's always good to know you have someone working on it that really has a passion for what they do.

While I understand this experience may have soured a little, I do hope that you'll consider us in the future. I will be sending your feedback to the appropriate departments for their review.

Again, I'm glad you're up and running. Please let me know if I can assist further.

Samsung LCD Model LNT406 XAC
Aug 6, 2010 2:35AM PDT

Wow, isn't this some good press for Samsung!?

Just writing to report we have the same problem. And also at time of warranty expiry.

Of-course these TVs are built with manufacturer intent to be disposable. They can't make money if your TV works wonderfully. If enough people do their research and find forums like this not only will they (1) have ZERO CUSTOMER RETENTION but (2) also lose potential new customers.

In the end, it seems that Samsung has deemed this an acceptable risk to their business model.

We're going to try and get ours fixed. If it's not possible, I'll make sure to replace it with a NON-SAMSUNG associated product. I heard they were a main manufacturer, not sure and haven't researched yet. I'll do whatever I can to make sure that not another hard earned red cent of mine ever gets to Samsung. At least be stand-up enough to accept responsibility for the problem and treat your customers with some respect. Alas, not only are their products disposable but apparently so are we, their customers.

Thanks Samsung!

I have escalated your issue to someone who can help get this issue resolved. I'll keep you posted when I hear back (I emailed the information and my notes this evening, and I'm often left out of the loop after that happens, but typically with good results), so if it goes well, you should be contacted or I will have an update. If you don't hear anything by next Tuesday, let me know.

Regarding your weekend, I'm sorry it's not going to be able to go as planned.
