Samsung Plasma TV - Won't turn on

I have Samsung 50" plasma tv model HP-S5053. The unit would not power on and blue light was out. Tried a different power source which did not change result. But now if I unplug the unit for a few minutes then plug back in, tv will power on for a few minutes then turn off. Also, now when I unplug for a few minutes and replug, it powers on automatically (without touching remote or power button), then dies again. In any event, it won't turn or stay on.

Samsung Plasma TV - Won't turn on


I'm sorry to hear that you're having this issue.

Unfortunately, there's not much I can suggest in the way of troubleshooting. It'd probably be best to have a technician come out and inspect your unit. If you'd like one dispatched to you, one can be arranged by calling 800-SAMSUNG.

Interestingly, I am having the same exact problem but my plasma won't power on at all. When I press the power button on the front of the TV the blue light blinks, tv clicks once, then the light turns off.

I find it ironic that I purchased my plasma (Circuit City) about 20 monnths ago (November of 200Cool. I called Samsung support and they claim that this is not a known problem but it is a known problem on the LCD Displays. I wonder if they used the same size capacitors in the plasma as they did in the LCD Displays. It's all over the internet, this is a problem.

I was so close to buying a Panasonic, instead I have a $2,000 investment that hangs on a wall that has died in 20 months and will likely have to fork out $300-$500 for repairs.

Samsung Plasma

I've got the same kinda issue going on. One day it was fine the next it won't come on. It goes through the power on tune repeatedly trying to power on but won't. Or it goes through a series of clicking sounds trying to turn on. Once it's on it's best to not power it down cause it may not come back on later. I also has tried disconnect power sources to reboot it but it's unable to power on.

My advice is to remove those from service before

Before something worse fails. There is some well discussed BAD CAPS issue but no one can see those over the internet and Samsung has been covering some even out of warranty. But folk that let it keep clicking are risking damage that won't be covered.

Samsung plasma tv wont turn on

I also have had this problem. I have a PN50C8000YF top of the line 3D plasma TV. After 1.5 years (outside of warranty) the problem occured as described. I took it to the Samsung recommended service representative in the area. At first he thought it was the power board but it turned out to be the main computer board. It had failed and no longer could send the power on command to the power supply board. $344 later I had my set back. If I hadn't paid so much for it in the first place I would have been tempted to buy a totally new 50" TV for less than $1000.

If you wouldn't mind. . .

I've got a Samsung plasma in the same family as yours, and just posted about this issue.;threadListing

In the post, I've linked to a youtube video of my issue. Is this what was happening to your plasma also? I'm looking to repair this myself, and was wondering if by "main computer board" you might mean the logic board?

Our TVs are similar and use many of the same boards, and I've found this listing of the boards in our sets,

Were any of these parts the ones replaced on your TV?

Thanks for the help.

samsung plasma TV wont turn on

My TV went off. when I tried to turn it back on the red power light went on and it clicked 3 times then went off. Same ting happened each time.
I looked at your parts list. My TV required the "main PCB" # BN94-03313A with a list price of $217Cdn. Slightly different PN than the one listed on your post.
I looked at the old board and could see no obvious external indication of failure.
When I originnally called Samsung, their position was that it was out of warranty. They provided the address for the nearest technician.

samsung Hp-s5053 plasma

Mine doesn't power up at all. It was working one day and not the next? Based on my research it appears to be the power source board.? Please let me know what you think? Greatly appreciated.

Thank you

You hit it right on.

My computer after about 20 months just did the same thing and i am wondering what you did with the problem. Did samsung stand behind there product or did you just hire a technician to come out and fix it?

Here's the Samsung Settlement link.

Many never asked Samsung about this. Some are blissfully unaware they should ask.

In other works, always call these in and ask.

My best advice is to remove from service till it's fixed.

Thanks for the link. I think that pretty messed up on Samsungs part. The TV's in the settlement are for manufacture dates 2008 and earlier. But it seems the same problem is happening in later models as well (like my 2011 model). The problem seems to appear shortly after the 1 year warranty expires. Bad business.

I wish I could agree.

The CAPACITOR PLAGUE was caused by other than Samsung. I will try to help you figure out why this happened.

Since this thread is more than 1249 days old, links may die. Sorry if I seem short on the BAD CAPS discussion but it's been cooked, re-hashed, re-fried so many times it's a little old.

Start a new post with full details, model number and a transaction number if there is something new to discuss.

Same Problem

I have the same problem as well. 43" Plasma...had it for 18 months...shut off and will not turn back on...clicks after I unplug and plug back in. But after the clicking stops, the TV still does not turn on. Sorry to hear it was a $2000 investment for you. Mine was $550 but I am very upset with Samsung and the way they handled my call. If this is a problem (as I've seen all over the internet) you would think they would help. There is a class action suit against them for certain model numbers (mine is not included) for the same problem I am having.

Along with mine, my brother had one that lasted 18 months (what a coincidence). His was a problem with the picture. Samsung was unwilling to assist him too.

Apparently their quality is bad, and their customer loyalty is even worse. I have a Sony TV in my living room that works great. My brother has an LG that works great. I will NEVER buy a Samsung again.

Sorry to hear your troubles. I just wanted to let you know that it has happened to many and the only thing we can do is not buy Samsung products

Samsung hd s5053 plasma has no power whatsoever

I fixed mine

All i did was disconnect the logic board from the power cable waited 30 seconds or so then reconnected the cables and ribbon cables back and pluged it in and its back working again. Hope this helps someone ftom forking out 120$ for sn unnecessary logic board save your money and try what i did its worth a shot

How ?

How do you get to the logic board, open up the back? Mine is three years old when it happened a year ago Samsung agreed to extended the warranty once and fix it, then it happened this year. They wont stand behind itSad I'll never buy another Samsung but if I can fix it I will.

Power Cable

In my case, I have had spurious times when my TV would not turn on.. When I played with the power cable, it would finally turn on.

In the end I changed out my power cord and it worked. My OLD OEM power cord must have had a bad connection or wire inside. It now works with a standard computer power cord.

Hope this helps.
