Shortly after putting the new bulb in, perhaps just coincidence, I noticed that in the lower center of the screen, there is a vertical "beam" or fuzzy streak of light that can be seen at times. It almost appears like a "leak" of light coming through. Usually, it is most noticeable during things l channel changes, where you have a moment of mostly dark screen. But one can see it if you know it is there while watching programming.

See attached pictures. In the first one, the photo also shows what looks like a dim mirror image of the information bar at the tops of the screen. I don't know what that mirror image is about, as you do not see that phenomenon with the human eye. The eye only sees the "beam of light" as in the second closer-in photo.

Any ideas as to what is going on with the TV?


I hate you meet people under these circumstances, but .. I would hazard to guess that your light tunnel collapsed. The light tunnel is a set of mirror that is glued to a framed tunnel. This is a well known issue. Most likely the higher heat output from the new lamp was enough to finally cause the issue, but it was going to happen sooner or later. See this link to get your set fixed: http://www.samsung.com/us/dlptvsettlement/

Thanks for the link but I am not having a shadowed-area-on-the-edge effect indicative of a tunnel collapse.


What I am getting a subtle but very much there light streak. It starts in the lower center of the screen maybe 5 or 6 inches or so from the bottom, with a crisp/defined beginning, and fades out left to right maybe 6 inches or so wide, and it projects and fades out upward for a good half the screen. Kind of a comet effect, if you will, as you can see in the pics. It is most noticable when the overall screen image is dark or black, as these DLP sets are quite bright overall and for most normal to bright programming, you would not notice it.

Funny thing is that sometimes when there is a totally black screen being commanded from a device (switching modes or something like that) the screen is truly all black. At other times for a black or mostly black screen, the streak is there.

I would look to see if there is light from inside the room going through the screen, striking the mirror and then being seen on the screen. (An environment problem)

It's not that. This is in a dark room.

Actually a dark room will make it easier to see a reflection off of the the internal mirror.

I say dirt, a lot of dirt. In the first picture it almost looks like dust on the lens is dispersing light onto the plastic on the inside of the set, and what you are seeing is the actual inside of the tv. In the second picture, I suspect that may be dust on the main mirror you are seeing. If you see it as a second image, that makes sense as well because what is 'on' the mirror is a smaller version of the final screen picture. This may be showing up now because the new lamp is so much brighter than the old one.

I would remove the frame/screen assembly (many screws from back into frame, a few at the bottom hidden under some panel) and remove it carefully. Check main lens and mirror for dust. The backs of the screen tend to stay fairly clean. Avoid ammonia products. Clean soft cotton with a bit of distilled water is the safest way to go.

Having a bad feeling that my bulb is getting ready to go. Its already lasted longer than the first one did. The 1st was replaced under the warranty I bought with the TV but on my own this time.

Is there really any reason to buy the housing, or should I just get the bulb only? I think the difference is only $10 or $20 so dont want to be short sighted but dont need to throw it away either.

Also when do you need to replace the ballast? If you turn my set off and back on without waiting 30 seconds or so, you can hear what I think is the ballast making a pretty loud buzzing noise. Not sure if thats bad or normal.


Thanks!

I have no idea about the ballast; first time that I have even seen it mentioned. I will be following this thread closely to read any comments about it.

As for the lamp & housing: I changed the lamp in my HLS6188 for the first time after over 3 years of use a couple months ago (it was still working fine BTW). I decided to go with the housing. I figured the extra $10 was cheap insurance with my clumsy fingers. Well worth it for me, made the swap-out real easy.

Don't have a bad feeling. If it's starting to dim and your picture quality is degraded, install a new lamp. Life's too short to skimp on picture quality in the name of saving a few bucks trying to squeeze lumens out of an old lamp.

This is simply a matter of personal choice. It is unlikely the housing is hurt by age, so if you're willing to take the time to carefully replace the bulb, go for it. Personally, I'm willing to pay the small difference for a complete package, thereby avoiding accidentally touching the glass, etc.

You only need to worry about replacing the ballast it you actually have problems with it, i.e. flickering lamp, shortened lamp lifespan, failure to fire up lamp,etc. I would venture to say most users will never need to replace their ballast. In the past, I had some flickering, and a quick search indicated it could be a failing lamp. However, if the flickering returns after replacing the lamp, the popular knowledge is that the ballast is the culprit. I purchased a new ballast from samsungparts.com over a year ago but the flickering never reoccurred so it sits in the closet with my spare lamps. If you do decide to replace your ballast, here's a nice how-to: http://www.fixyourdlp.com/lampguides...33A_guide.html

Yes it's bad, and yes it's normal (or rather expected). You should not be power cycling the set without waiting for the lamp to cool adequately. The buzzing will occur otherwise. This behavior is hard on the lamp and the ballast.

Thanks for all the advice. I don't make a habit of turning the TV off and on, but it does happen on occasion. The wrorst is when I was attempting to troubleshoot the overscan problem before I gave up.

I do think my picture is degraded. It's been probably 3 yrs give or take. The first one only made it 2 yrs, but I think my wife left the TV on all night sometimes when I was working out of town then. Can a dim bulb affect picture clarity?

I will order one Monday. Let me know if you have any great sites to get it from, otherwise will just go to Amazon and look at vendor ratings.

Ever heard of the overscan issue getting worse? It may be in my head but it sure seems like it. I have a calibration disc I can use to measure it.

Power cycles affect lamp life more than cumulative hours.

No. However, broadcast television is starting to take advantage of screen real estate. The inability to permanently override the overscan is, in my opinion, the greatest downfall of this model.

Theres an HL-T6756 (model one year newer then the hls this thread is about) isf pro calibrated and comes with an extra lamp, currently for $56 on ebay with one day left.

I work at home so my HLS6187 is on for about 15 hours a day. A few minutes ago I decided to access the service menu for the first time ever just to check my bulb usage. I have read that making any changes in service menu can lead to problems so all I did was a little scrolling and came upon "Bulb Life 19,240h". At that point I did not click on anything, just powered off and then back on. What I am wondering is, is the 19,000h the actual hours of usage (or maybe just the projected lifespan)? Should I have drilled down further to get the actual bulb usage information? Thanks.

No. Specifically, the heading is "Lamp Life". It is the cumulative amount of hours your lamp has been burning. Keep in mind the SM does not know when you replace your lamp, so if you want this number to remain accurate, you need to clear the lamp hours when you replace the lamp. "Lamp Clear" is the option immediately above the "Lamp Life" setting in the SM.

Here's a screen shot:

Has anyone ever seen the overscan issue get worse over time?

I used to lose an inch top and bottom and 1 1/4" on the sides. I could set my Oppo player to underscan and just barely see the black border around the outside. Now with the Spears and Munsil disk in using the screen I still am missing 10-15 pixles on all sides even with underscan on.

Having some issues now with my four year old HL-S6188W. The TV will turn on fine but then after a few seconds, it will shut off with the dreaded 3 LED lights blinking. I wouldn't think this is a lamp issue since it does turn on and I can see the picture.

I did search this thread and tried taping the blue safety switch down and re-seating the lamp.

Anyone have any other suggestions or what the issue can be?

The lamp could still be the culprit. While it may still have some life in it, it may not be enough for the ballast to keep it "lit".

I think you are correct. When the picture is about to go off, I can see the picture getting noticeably darker and even a little flicker. And then it shuts off. I went ahead and ordered a new lamp. Talking with Samsung tech support, they are very confident it is the lamp.

It's the bulb for sure. My second bulb did exactly the same thing. New bulb=new TV

That is good to hear.

This is still my first lamp, and I bought this TV new when it first came out. I know I shouldn't be cheap on getting a new lamp, but I had to see how long this thing could last.

Stop being cheap!

You got way more life out of the bulb than anyone could expect. Don't they have an estimated span of less than half what you got? Regardless, just pay the money and get a new bulb. If yours is dying, then you'll be blown away all over again just how good this set can look! Do it now. Put the old one away for an emergency. Don't wait for it to die first. If you wait for it to die, then that will be the time the company has none in stock and it gets lost in the mail two weeks later when they can ship one.

I have the 6187 and I just ordered my first replacement bulb for the set that I bought sometime in 07. My settings on the set are the same that were recomended to me by a poster on this thread. Years later are those settings still good? Are there any "improved" settings users have found? I like this set but I found it can be a little dark for my tastes. Any advice for settings that would give me an acurate picture yet a little brighter?

Haha. Yeah I already ordered the lamp Sunday. The crappy part is I paid for expedited shipping thinking it was coming from New Jersey. Then in the UPS tracking, it was shipped from Cerritos, CA which is 100 miles from where I live. So it is was delivered today which is a good thing but I lost ~$20 on "faster" shipping.

I probably don't realize how much PQ I have lost over the last couple of years but I will find out tonight.

I thought I was going to see a ton more hours on mine when I checked... I have had it since December 2006, and have about 10,200 hrs. Is it worth replacing the bulb yet?

I got a new lamp and housing from Samsung Parts just before Thanksgiving. The difference was night and day!

Just today I got one green and one red LED blinking together and then it shuts off. It'll relight, but then after a few minutes they blink again and it shuts off.

It's not the three LED's meaning the lamp has reached the end of its run, just the green and red.

Anybody know what that means? Overheating? Ballast trouble? A lamp error?

I have a HLS5688. My last lamp started to darken at 2000 hrs. The one before it did last very long either. Neither lamp died, but just started to darken to the point it was noticeable to me. I am wondering f it is time to change the ballast. I also noticed that the lamp fan is getting a little noisy. Maybe it is weak and not cooling the lamp as well as it should. Any comments?

Update. I just replaced the lamp. It looks much better but I noticed that I am starting to lose some detail in darker areas of the picture and in light to dark transitions It reminds me a bit like "gray face" that the earlier DLPs used to get. Any ideas?

Thanks

Hey guys. I'm new to the forum but I've always used AVS forum as a guide when purchasing any new electronics, especially my HL-S5087W 4 years ago. I'm hoping that the experts on this forum will be able to help me out with my problem.

So my TV is 4 years old but I have probably only used it for <500 hours. Just recently I went to replace a cable box and noticed there was no picture on the TV. It was a blue screen, but I could hear the audio from the cable box. I tried switching boxes and cables to see if that was the problem, but no fix. I even switched to my other inputs to see if they were working, Nope! Both HDMI inputs, composite video, and component video inputs all display a blue screen, but the audio works. I am able to display the menu on the screen, but no video source picture is displayed!

Anyone know what is wrong with my TV? I'm assuming one of the boards/fuses has malfunctioned.

Hey what did you guys use to calibrate your set? I'm looking for a recommendation on a calibration disc or even some video settings I should use? Thanks!

My 6188 was ISF calibrated over three years ago. However, I currently have both DVE, and Disney's WOW, Calibration Blu-ray Disks. If you have never calibrated your TV then you will likely be in for a real treat after proper calibration.

If you do not want to spend the money for an ISF Calibration, then I would highly recommend Disney's WOW Disk for first time calibrators and even for just about everyone else. DVE is still a kind of a pain to use although it does have many test patterns; probably too many for most non-professional users.
