There is also a great youtube video on replacing the red LED. It isn't as complicated as one would think:

TV was great for 3 years and then one fine day - boom.

So I opened the back and started tinkering around. As soon as I turn on the TV, there is a clicking sound every few seconds .... and it seems to be coming from the main Digital video Board (part # BP97-01193H as printed on the board). The LED lights in the front start blinking and then the red led light stays on. This goes on for about a min and then no power at all. Unplug the power and plug it in ..... and the process repeats itself.

Checked the fuse on the power supply board and it is fine. "Visually" all the capacitors seem fine. A quick trip on youtube tells me that it may be a capacitor problem. What am I missing ? Could it be a capacitor problem bu the capacitor has not "popped". Hoping the folks here can help me. Love this TV and plan to extend its life. Any help greatly appreciated.

The capacitors won't necessairly "pop". Look for any whose top appear domed instead of flat.

Tv is nearly 4 yrs old and I have been having a issue on startup lately. I can hear the fans turn on but it takes an extremely long time to come on or it doesn't come on at all(screen just goes dark). If I unplug it and plug it back in, it will power up almost immediately as it always has. Any ideas? I took the back off and cleaned the dust of everything. Didn't correct issue.

thanks
Jeff

Can anyone point me to the Samsung LED DLP service manual, or, even better, directly answer my question? I have a 6187S with sound but no picture, and I've checked and confirmed w/a 9v battery that all the LEDs are good, so I'm looking for a manual to take the diagnostics to the next level. Thanks in advance.

I am having the white dots issue, so I know it’s the DLP Chip, tried calling Samsung and they will not replace for free. So, I started checking craigslist for DLP TV because I found out that there are many DLP TV with the same chip. Lucky enough after about a month of looking I found the same model I have HLT5087s for $200 negotiated down to $125 with the Red LED problem, and he said he just changed the DLP chip a few months ago and didn't have the time to replace the LED.

Now I have 2 of the same TV with different problems, I am very comfortable taking these apart, done it many of times, Halo issue, replaced Screens twice.
I am trying to find out what is the easiest and fastest way to get one TV to work.
My questions are:
Should I just take the Red LED out of my TV and replace the bad one?
Or should I replace the DLP chip?
Or is there an easier fix?
post #13957 of 14847
FYI
I ended up replacing the Red LED, it was pretty easy, but did take my time cleaning it.
Wow, the dust really built up and the cooling fins of the Red LED. I do think that it did overheated and burnt out.
post #13958 of 14847
great idea to get a spare TV for parts, Dave. Wish I could...
post #13959 of 14847
B*** B** came out to diagnose the white dot issue on my DLP just before the 4-year extended warranty expired, they are bringing a new DLP chip in a week-and-a-half. My question was, since this set was ISF-calibrated some time ago in the service menu, will the new DLP chip reset all the settings to default or is this stored on the DMD, motherboard, or something else that they are not changing? I tried searching for this but I couldn't find it in this thread.
Thanks,
Jeremy

I think that your setting will be ok, but I'm not fully sure. Even if it does reset its better then looking at all of those white dots

My 5087 turns on but no picture at all, and no error lights.

Is the light engine toast?

The past month or so as well, I noticed a black spec on the screen, and from more research it looks like this is a common problem, could the two issues be related?
post #13962 of 14847
I have a Samsung HLT5089S, after i watch for while the audio drops out, i used the Samsung online customer service but they were not any help they asked me it the TV had power and was on and if the Mute Button was on.
Which was totally useless. I was asked to open a Ticket, but I never got a response.

So far the way i am able to get the sound working again was to power off the unit and power it back on. This happens when i use Either of the Antenna inputs (OTA as well as Cable).

When i looked at samsungs website i saw that there was a firmware update listed. I downloaded the files placed them on a USB Flash drive and ran the .exe on the flash drive. Before i did any updating i wanted to do some additional research and i saw multiple incidences where the unit was bricked. So i decided to write a post asking..
(Note: Version TXT from the download says 1019)

1)is 1019 the current version
2)if anyone has had this error/problem
3)How to determine the current Firmware prior to running the update
4)if the Firmware update still bricks the unit

Anyway can anyone answer these question(s) and if they know of a solution?

Thanks

Edit1: I posted on this on Samsungs Facebook page and was emailed 1019 was the Latest version and was sent a nonworking link on how to check the current version. LOL

Edit2:Well Samsung got back to me, and told me that the procedure so i tried it.... I had version 1011, Now I have 1019.
I had to figure out the washedout black and the Tint control was related to the picture mode being in standard instead of movie mode,
but alas... After i figured out the video, a few hours later i heard a POP and the audio went out again so the audio problem still exists.

I did notice the Blue light on the bottom of the TV Does not Light anymore, (the Blue light came back on the Next day) I was able to figure out that the problem is with either the internal audio amplifier or the speakers themselves because when i plugged phono plugs to audio out on the TV to my stereo audio input i heard sound !!!

I am thinking its the power supply that feeds the audio amplifier because its kind of strange that the speakers both go out at the same time, but that is just a educated guess.

At least I can watch and Hear TV even though i have to use my stereo. I still want/need to fix the internal speaker/amplifier issue because i dont need too hear CNN in surround sound (and i rather not use the extra electricity to run the stereo).

Hopefully Samsung can help me with a Part that I can swap.

FYI.. IN the future... I will Stick with Sony.

harveygfl - you can source a service manual for your TV online for @ $20. Then it's a matter of troubleshooting and replacing internal boards. Unless you're a technician, you may not identify the correct board on the first try. I know we all want our TV's in perfect working order - if everything else is fine with your unit, why not buy an inexpensive set of computer speakers and use the audio out from the TV to drive them. The internal speakers on your model are only 10 watts each, for a total of 20 watts, so you wouldn't need much to equal them, and your electricity use would be far less than using your surround system. This would be cheaper and easier than trying to replace a board. If it was your light engine going on you, I would say go in and replace it...

Seeing what looks like purple splotches on the screen when no there is no input and the screen is blank. I don't notice any other issue with PQ when there is an input signal.

I have the HL-T6187S. Anyone experiencing this issue or know what this could be?
post #13965 of 14847
Search this thread for "blue halo". If that is what you are experiencing, this post has an excellent guide to fixing it yourself.
post #13966 of 14847

If the purple splotches show up when there's no input signal or a completely black screen, then it's probably not "blue halo". The classic "blue halo" requires a bright area on the screen to cause the blue reflections.

Not sure, but it appears when the "check signal cable" on screen message comes up (in the blue colored box) that there is no input. I see the blue/purple splotches under and around that aqua message box. When there is a blank screen from an input (like a blank jpg), then it looks fine.

Since this isn't causing PQ issues, is this a problem or just an annoyance? My set is at the end of the 5 year warranty contract, so wondering if I call for service if they'll even know what I'm talking about.
post #13968 of 14847
What you describe sounds like the blue halo. Try the test image that is part of the link I gave you above. My TV has it but the only time I see it is with the test image. For me, it is a non-issue. If you see it while watching TV then it may be worth fixing. Samsung has a replacement part that can be easily swapped out. It does not affect picture quality as it is simply a reflection that occurs only during specific scenes - typically when the top half of the screen is very bright while the bottom half of the screen is dark.
post #13969 of 14847
Blue halo is a problem with reflections in the optical system of the set. It will occur under the right circumstances no matter where the signal originates.

If your set shows the problem with the "check signal cable" message or with my halotest.jpg file, then it can happen during normal viewing, even if you don't notice it.

I first became aware of the problem, with my set, when I was watching a letterboxed widescreen movie (approx 2.4:1). Blue and purple blotches were showing up in the black bar at the bottom and stayed there if I paused the movie when they appeared. They didn't appear when I viewed the same scene while playing the movie on my computer using its monitor.

Look at the "heroes" image from an old post by me, if you want to see an example of the problem in normal video.
post #13970 of 14847
Thanks for the help guys. I'll look into fixing. I love this set, so even though I could replace it, I'd be happy to keep for another 5 years.
post #13971 of 14847
I had the same problem that a lot of other people are having with the picture being blue/green. I ordered a replacement from samsungparts.com and replaced it. I noticed that the new(?) part I received had traces of paste on it but I went ahead and installed it. I'm still not getting any red.

I can think of 2 options: 1) The new(?) LED I got is actually from a refurbished model and is bad; or 2) the light engine is bad. Before I call and raise heck, is there any way to troubleshoot the light engine itself?

i read a post on this site that you can test the led with a 9 volt battery and it should show red.i am not sure where it is located in the posts but i know a service technition used this method.

For the last week or so, this happens when we turn on our tv HLT XX87. We then turn it off and back on in appx 1-2 minutes and then it works again until the next day. Any idea's on this problem?

I've followed this forum a long time and I'll have to say, this is the first time I've seen that one. Sorry I can't help.

Lucky me I guess. I have been following this thread for a long time myself mostly as a lurker but like you I have not seen this issue. Hopefully someone has. Starting on Thursday morning (12/15) it started something new. The TV will not turn off by remote or the on/off switch on the TV?? WTF is going on?

Anyone know?

Well I got it to shut off by killing the power to the surge protector that it is plugged into. I waited a few minutes and turned on the surge protector and tried the remote again and it worked if it didn't I was just going to start killing the surge protector to turn off the TV instead of leaving the TV on 24 hours a day. All I can say is I hope it holds in there a while longer 4 1/2 years is not long enough for the freaking appx $2500 it cost in my opinion. Hell even our last RP lasted a while over 10 years.

I agree. I had my previous TV for 8 years before I replaced it with my HLT6189. The old one is still in use and will probably will still be working long after my HLT has died.

I re-arranged the room where the my HLT5687 is located. I moved it over to a temporary desk and then decided to clean the inside. I unscrewed the dozen or so screws in the back of the TV and tried to separate the front panel but couldn't get it off. I abandoned the project for the time being, put back the screws and moved the TV to the new stand's location.

Since plugging it back in the TV will shut off when i'm pressing buttons other than Power on the remote. Not only that but it will respond to other device's remotes. For instance i'm using my h/k receiver's remote and certain actions will turn off the TV.

First bug since i've own this gem of a display, so can't really complain. I'll search around and troubleshoot during the week.

It's so small I can barely measure it.


post #13979 of 14847
Can someone help me please, i bought a used samsung hlt 6189s and i am experiencing a slightly blurry/fuzzy picture quality, even the menu on the tv looks a bit blurry, is something dirty or dusty that i need to clean or is it something else that i gotta replace? if someone can help me out thatd be great. thanks!!!

i use to have a 61a750 and havent had this issue before.
post #13980 of 14847
NvMySi,

Your new set may need to have the focus adjusted. I posted previously in this tread on how to adjust the focus. Read on from that post for a few more details.

You could also clean out any dust in the optical path, while you're in there, in case that's the problem.
