Samsung TV Keeps Shutting Down

by frybecker / November 8, 2008 11:50 PM PST

I have a 4 year old Samsung TV (Model HLP5063WX). When I turn the TV on for the first time each day it shuts itself off within 30 seconds. It repeatedly shuts down anywhere from 10-12 times before it stops and we can watch the TV.

Has anybody else experience this issue and what did you do to correct?

We have not. Is this a sign that the lamp needs replaced? This has been occuring off and on for several months.

When the unit turns off, there may be a light blinking on the front panel. Depending on the frequency and combination of that flashing, you can probably diagnose the issue if you still have the manual. If you don't, tell me which lights blink, and I'll dig up the manual here and help you diagnose it.

In some cases, it could be that the bulb isn't responding like it used to, which sends a signal to the board that there may be an issue. But before I get ahead of myself, if you could just describe the panel lights in the front the unit the next time you "cold-start" your television and it doesn't start, that would be the best step in the right direction.

Also, has it gotten worse in the last couple of months? Any detailed description you can provide (1-2 attempts, then 3-4 attempts, then 5-6 attempts...) that would give me some sort of progressive range would be helpful as well.

Tall order, I know, but information is power.

This morning the first two times it shut off the "Stand By/Temp" light came on. The third time the same signal came on plus the "Lamp" light was flashing. I also did notice that the first time I turned on the TV the "Timer" light flashed briefly. I had not seen this before.

I ususally have to restart the TV 10-12 times from a cold start every day. This has been occuring for the last 8-10 months.

Okay, here's a quick guide I copied from the manual.

So we're narrowing it down to a couple of possibilities. It could be the lamp, or it could be the fan. If you can hear the fan, it's likely going to be your lamp.

Here's a Samsung_HD_Tech quick fix, and I'm throwing it out there because I've done this numerous times in my line of work, and more times than not, it works.

I'll walk you through a process that will "Re-seat your lamp". If you locate and open up the lamp housing, you'll see your lamp.

Here's an example of what you'll see:

Now, if you either unscrew the two screws where the yellow arrows are, or the one screw where the red arrow is (Depending on the model you have), you'll be able to pull the lamp out a little. Don't worry, the screws shouldn't fall in the unit, as they should be attached to the lamp housing.

You don't have to pull the lamp all the way out (if you do, that's okay), but if you pull it out a little (6 inches or so), and then <b>firmly</b> push it back into place and rescrew it in, and close up your outer panel, that may very well fix your problem.

The outside panel does need to be back in for the television to turn on. There is a blue kill switch there, but you don't want to fool with that.

A few general rules here.
1. If you do pull the lamp all the way out, do not touch the glass face.
2. Perform this procedure while the lamp is cool, and preferably not after consecutively watching Star Wars Episode 1-6. Happy
3. If the first one doesn't take, try re-seating it again. It may take a few times to reset whatever is triggering the warning.

If it doesn't work, and you need a new lamp, you're already a pro at knowing how to install it. But I do think that if your brightness levels are acceptable, that a simple reseat may very well fix your problem and give you more time on that lamp.

So a recap: Unscrew the lamp, pull it out a little, firmly push it back in, rescrew the lamp, and close it up and see what happens. It sounds crazy, but if it fixes your problem without a service tech OR a new lamp, that'd be a good thing.

Keep me posted!

Hi I have a Samsung hl72a650. Replaced lamp a year ago. Tv suddenly one day started to shut itself off and back on again. I have tried everything else I have researched online. Took lamp out and back in several times. When the tv comes on the picture is very bright and clear then suddenly the picture begins to loose color and shuts off and back on several times untill all 3 lights start blinking. I also started the tv with mute 182 power and selected options clear lamp, reset user settings and reset factory settings. I get the same result. If I leave tv off for a while ant reporter up the picture comes up again perfect for a few minutes then off again untill again all 3 lights start blinking

Same Problem as person in "In Some Cases" had
by rochkrill / September 22, 2016 9:22 AM PDT
In reply to: Indicators on DLP

Our Tv has exactly the same warning lights flashing on the front so we went down and bought a new light and replaced it but this didn't fix it. When my tv shuts down after about 30 seconds all three lights blink stand/by temp, timer, and lamp. It also will make a dinging sound that sounds like an alarm kinda when I try to turn it back on. I have done some reading and it said that possible the timer needed to be reset but when I go thru the process which says I should press mute+1+8+2 then power and a screen will pop up this does not happen. I have also tried to press menu+1+8+2+power and no screen will pop up to reset the timer. could you please help me. Thank You

Samsung DLP HLN617WX Timer Light Flashing
by AzForgetMeNot / December 21, 2008 1:17 PM PST
In reply to: In some cases....

Hi HD Tech ! I wanted to post off of this thread because I wanted my problem to be answered by you as you seem very knowledgeable about Samsung DLP televisions. Let me explain to you the problem I am having with my Samsung DLP tv Model# HLN617WX. The timer light is flashing green when I press the red off button on my remote. No other lights are flashing. The tv will not turn off with the remote or the side buttons on the tv. Nor will it turn off with my cable remote. I have looked at my manual and several combinations are listed as to what the lights mean when they are flashing or steady burn, but, not the timer light only. I replaced the lamp on it about two years ago, but, I don't know how many hours are on it. I am afraid to shut it off and try the Mute (or menu button) + 1 + 8 + 2 + power to see how many hours. I can hear the fan working and the tv makes no noises as to suggest it is the color wheel or ballast. Do you have any idea as to what this is ? Thanks for all your help.

by Samsung_HD_Tech Samsung staff / December 22, 2008 6:05 AM PST


Thanks for your kind words.

I would definitely recommend reseating the lamp, as per the directions listed above. I don't know why, but that seems to solve many of the issues.

If that doesn't work, the symptoms where the buttons AND the remote don't allow you to power it off suggest that you probably require a service technician.

Try the re-seat and let me know how that works. I'll see what other information I can dig up on those symptoms.

In reply to: Symptoms....

Samsung HD Tech: Now when I press any button on the remote I have no power, not even the timer light blinks, unless I unplug the tv, press the mute(menu)+1+8+2 buttons, then the tv will turn on in regular mode, not the service mode. Yesterday, the screen, after the tv was on a few minutes had horizontal lines that looked like hundreds of tiny colored boxes, mostly blue, and no picture. Today we turned the tv on using the above "secret" code and turned it off and back on successfully twice by only pressing the tv and on buttons on the cable remote. The second time took a few moments for it to come back on, but, it did and then my son refused to let me try it again. As of right now, the tv has been on for about 45 minutes with no problems. Help !

Samsung DLP Model HLN917WX Ballast
by AzForgetMeNot / December 23, 2008 4:23 AM PST

Samsung HD Tech: Can you tell me what the ballast does in the tv ? I understand the ballast regulates the electricity flowing into the tv and maybe that is bad and is why I can't power the tv on? If it is the ballast can you let me know the part number I need to order ? Thanks for all your help.

by Samsung_HD_Tech Samsung staff / December 23, 2008 6:32 AM PST


It could be a ballast. Does your lamp light up internally (look in the back and see if you see white light emitting from the vents)? If so, it's probably working correctly and you could probably narrow it down to the power supply or the DMD board. From there, it really takes a qualified technician to come out and figure out which one is the cause of the problem.

I wish I coul diganose it further, but we can probably narrow it down to one of those two things. To your credit, you've given some excellent descriptions; however, at this point, it's speculation at best.

If you're interested in getting parts, you can find all the available parts here at this website:

I think I figured it out !! Samsung Model HLN617WX
by AzForgetMeNot / December 23, 2008 1:43 PM PST
In reply to: Could be...

HD Tech:

I think I figured it out !! Yea !!! In May 2007 I replaced the lamp. At that time, I didn't know it was necessary to reset the lamp timer when the lamp is replaced. I also didn't know the "secret" code you enter in order to get to the service menu to reset it. Anyways, I reset the lamp timer a couple of days ago per instructions I gleaned from many websites, but, I didn't remove the lamp. I thought that would fix the issue, but, it did not. Only after you mentioned to me yesterday to remove the lamp and re-seat it, did it dawn on me, that perhaps the computer board knew, that although the lamp timer had been reset, the lamp had never been removed. I opened the back of the tv and the lamp door and verified that the lamp is working as well as both fans. It was quite dusty in there, so, with compressed air and a vacuum, I cleaned the tv. I also took out the lamp and re-seated it. The tv has now been on several hours with no problems. So, in answer to my original question, that only the timer light was blinking when the remote buttons were pushed and the tv would not turn on, perhaps, it is a safety feature built into the tv circuitry, that, when then lamp timer reaches a certain number, the tv becomes "locked" until the lamp is either changed or re-seated and the lamp timer is reset. I am interested to know what you think about my "light bulb" moment and explanation. Out there or possibly correct? Let me know. Happy

Hey, that's great news! (You mean you read through that whole thread and didn't reseat your lamp?!) Happy My bad, I had assumed you had.

I've seen DLP units with timers of 8000+ hours working. I don't think there's a point where the DLP would shut off "just because" it "thinks" the lamp should be replaced.

As well, because we don't assume that the average customer [ahem] would know the service code, we naturally don't require you to reset the lamp timer. Some of the later models will note when your lamp may be needing to be replaced, and that, I honestly have no idea what triggers that warning (however, I'm pretty sure it is independent of anything to do with the timer).

So the answer is "maybe" because I'm not 100%. Let me see if I can find out anything definite. In the meantime, enjoy your television, and keep me posted of developments.

HLP-4663W, about 4 years old.

After being moved by professional movers the set began to turn off by itself. I thought it was a ventilation problem as changing the air flow resolved the problem for a while.

I reseated the lamp several times. I installed a fan to draw room air through to the intake on the side of the set. Both fans that I can see (near the lamp and off to the right [from behind the set]) are turning when the set is on.

The lamp was replaced around October of 2008.

Sometimes it just shuts off (stand-by light comes on), other times the screens goes blank, but no lights on the power button, and other times I get a blink code on the Standby and Lamp lights. I will record that the next time I see it happen.

As a post up-thread mentioned, I'm also experiencing that I have to turn it back on several times before it will stay on for a long period.

In the mean time, any tips?

In reply to: HLP-4663W

Well, reseating is about the only thing I can suggest.

You might want to make sure the air isn't blowing into the exhaust. Wink But if it does that with or without the fans, I'm not sure what the issue could be.

I wish I had the answer, but reseating is the best fix, and usually works.

Keep me posted.

secret code to reset timer

Could you share that code? I have a HLN5065 that will not turn on. I replaced the lamp but the tv screen will have a momentary flash of light on the screen then it will turn on and off endlessly, never a picture comes on. Thnks

Collapse -
by Samsung_HD_Tech Samsung staff / January 12, 2009 10:49 AM PST

The service code should only be used by an authorized service technician. If your television isn't turning on, this code will likely be useless anyway.

You're best bet is to have a technician come out and look at your unit.
