Samsung 1080p Owner's Thread --- HLSxx87W/HLSxx88W DLP Models - Page 706

I agree I would say Color Wheel or the Fan.

Research does seem to indicate that it'd either be the color wheel or the fan. Is it fair to assume that a few seconds of humming after power down points to the color wheel and 30 seconds of humming after power down points to the fan?

I bought the HLS6187W in fall of 2006. Other than 1 repair call to replace a noisy light engine which was under warranty, I have had no problems. Amazingly I have not had to replace the bulb yet, which I am estimating at 4.5 years old as the new light engine came with a new bulb. The picture is still fantastic and I think it will still compare in quality to the new sets out there. Very satisfied with this TV, just dreading the eventual light bulb replacement cost.

I have a 6188 about the same age as yours and the only thing I have had to do so far is 1) replace the lamp, and 2) have a service call to correct an odd audio problem (the tech just did a master reset and that fixed the problem). My main point though in responding is to not worry about changing the lamp, they are not real expensive if you shop around, and replacing one is an easy DYI project.

Thanks for the feedback. Just to save some time from searching through all the back posts, did you go OEM or aftermarket lamp/bulb? Are they just about equivalent?

Here is where I got mine: http://www.discount-merchant.com/

They sell new OEM parts at very good prices.

Stick with OEM IMO. Its just over 100 shipped for the bulb and "case" well worth it.

Update on my Sammy. Replaced the color wheel two days ago and the hum has disappeared.

My 5 year old HLS5687W has been working fine with only 1 lamp replacement... until now.

Last night it displayed a red screen with lines in it. When I powered it off and back on it did not come on. Nothing, nada, zilch.....

I unplugged it. pressed the power button for >30 seconds. Powered it back up. Still nothing. No menu screens, etc.

When it powers up one light/LED blinks for about ~1 minute then it stabilizes with no lights (and NO menus) then it shuts itself off.

I fixed the lamp cover "door" switch problem long ago, So it is not that.

The lamp "light" is on and light is showing through the lamp vents in the back of the TV and I can hear the cooling fan running. But no picture, no menus.... no front led pattern......

Please, any ideas as to what else I can try to isolate/identify the problem befro I call a Samsung Service center?

TIA!

After searching this thread for a while it would appear that the likely problem I am having is either the "Main Signal Board" (expensive) or the "Main Power Board" (not so expensive).

1) Has anyone replaced these boards themselves?
2) Where can one get a Service Manual for the HLS5687W? - Got one... Thanks...

I repair computers and have no fear regarding opening up the case if I have the service manual....

Any feedback/advice would be appreciated. We are pretty happy with the TV and are not interested in buying a new one if the repair can be made successfully but the nearest authorized service center is SEARS and they will not be in this area until next Tuesday.

Anyone have any experience with the quality/cost of Sears Service on Sammy DLPs?

Edit: Purchased and received Service Manual. Samsung board prices are high but not too bad..... any help on identifying which part is the problem would be greatly appreciated.

Service manual suggest "replace the DMD board".

Talked to Samsung.... they want to send a service tech out (at my cost) to identify the problem.

Talked to J&J (Samsung Parts). DMD board and DLP chip are 2 different parts and no refund policy. DMD board as much as $350 and DLP chip as much as $250.....

Might have to let a service tech handlesimply because I cannot be sure WHICH part is the culprit. But that won't help if they are going to charge me for parts that don't fix the problem anyway....

Same question, anyone have any experience with SEARS as autorized Samsung DLP service reps?


Also, I noticed the light coming out of the lamp "grill" is half white and half "purple". I never noticed that in the past. Anyone else notice this?

Thanks!

I think this is the most logical solution. It's too risky buying parts when you aren't certain they will resolve the problem.


Can't help you, there. I have no experience in that department. But, if they're authorized Samsung techs, I wouldn't be concerned. Their work should be warrantied.



Yes. The glass on the back of the lamp has a purplish tint. Then there's a "hole" that allows white light to leak out the side of the lamp. I've noticed this with all my lamps (at least 5). It would stand to reason this is normal. Those of us who have their TV's close to a white wall notice this more readily.

120inna55,

Thanks for the feedback. Talked to Golden End Home Service (service company Samsung Support suggested). Based on my problem symptoms they also belive it is the DMD board.

Cost Breakdown:

Diagnostic Fee: $100
Service Fee: $190
Parts (DMD Board): $300
-----------------------------
Total $590

Yeah thats a ^&%%&. But as you point out they warranty the repair....

I would only consider a "high end" replacement TV which would be in the ~$2000 range and we are (were!) happy with HLS5687W. My concern is that something else might break... but that is always a risk, even with a new TV.

Decisions, decisions....

Hello, I always use my big screen TV as a massive PC monitor. Just curious to know how well these Samsung DLPs will handle fast vertical scrolling with dark fonts.

Will black text separate into annoying rainbows? I browse web pages very quickly, if rainbows pop up constantly, that would bother me way too much.

Well, Golden In-Home Service techs just left.

They replaced the MAIN BOARD ASSEMBLY. So getting them saved my bacon as all indicators were that the problem was the DMD Board. So had I pursued the repair myself I would have bought the wrong part which could NOT be returned.

Total price was $490 ($300 Parts + $190 Labor). Took about 1 hour plus or minus.

Was it worth it? I think so since the replacement units I was looking at were all in the $1500-2000. To each their own.

What caused it to fail? Hard to say but we are subject to frequent power blips (quick on/off hits) during storms, etc. Everything is surge protected but electronics does not repetetive on/off cycles. Who can say...

On a bright note the Golden In-Home Service Techs get A++++ ratings for courtesy, knowledge and professionalism. They operate out of Buford, GA. and are authorized Samsung Service dealers. So if you ever need them, based on my experience, you are in good hands.

I'm glad you're up and running again.

I understand the conundrum you faced. It's hard to dump a lot of cash on an aging set, but if it still performs, it's hard to dump the set. The alternative is to buy a new set and upgrade. A true upgrade may run you about $1300 to $2000. It's hard to know where that threshold is. Only time will tell. If other parts start failing soon, you'll be kicking yourself. Ultimately, I think I'd have made the same choice you did.

What a helpful thread. So no one here has ever linked a PC to their TV? How brilliant.

Picked up an HL61A750 and it's amazing. No rainbows there. Come to mention it, no color wheel or UHP lamp either. Three high intensity LEDs, each with very accurate primary color rendition.

Are you serious? Many of the owners of this TV have moved on as its reaching 5 or so years since it has been released. The traffic on this thread is few and far between as you can see so getting an answer it going to take more leg work than it used to. From memory I don't think many owners here even hooked up their PC to this TV. Good luck with your new TV.

Sorry for coming across as a snot.

I know, just very impatient for a quick response to a simple question.

All's well, take it easy.

Well I checked my lamp life this morning. Still on the original, we bought it in spring of '07 maybe? It was a 16600 hours. So I'm off to order a new lamp today!

Other than that, knock on wood, the set has been great with no issues. Only thing it's done is for some reason it doesn't chime when we turn it off, or can be sporadic when it does. I don't think that's indicative of anything wrong however? Please correct me if I'm wrong there.

My fan #2 died so I got a new one and was ready to install. I took off the old one and then went to place the new one on the light engine, but then I realized that I forgot which way the fan should blow. Should the fan blow into or out of the light engine? Or should the guards of the fan be on the inside or outside? Thanks.

Sorry if this is really old news or something, but I noticed this the other day and just thought it might help some of those using the VGA input. Believe it or not, this TV displays 1920x1200. Don't ask me how or why, but if I'm using the VGA input and try setting the resolution to 1920x1080, it will not work properly with the TV (says no signal, or defaults back to different res), but 1920x1200 works flawlessly and fills the whole screen.

Hi all! Been a long time since I visited here. I bought my hls61 back in 2007 and it's been great, until today. Every time I turn the tv on, it lights up, shows a picture for about 30-45 seconds, and then the screen goes black and the three blinking lights start. It sounds like the color wheel and fans are working properly. I'm hoping this is just the bulb. I got 13,000+ hours on this bulb from the SM. Any suggestions, and where to buy a new bulb? Thanks!

Yes, it's your lamp. I like http://www.samsungparts.com (aka J&J International, inc.) for an OEM lamp.

Thanks! I wasn't sure since the picture was coming on for a few seconds, but I'll start there.

The ballast has trouble firing-up a lamp on its last leg.

For the last several weeks, I have searching the Web for solutions to fix my Samsung DLP. I have looked at some of these threads and applied some solutions to the symptoms below. Unfortunately, I have not resolved my issue--I am really stumped here!!!

Symptoms: sound, no picture (sometimes)

Details: When I turn on the tv, the background somewhat flashes as if the LCD's are starting up while the "LED" indicator on the bottom right hand corner of the tv blinks for about 1 minute--then the LED light turns off. Within that minute, the sound turns on. I can even change the channels with my remote. On occasion, after unplugging and turning on the tv multiple times, I can get picture--very clear picture, good as new. There are no color deficiencies.

What I have done so far and what I have observed:

1. cleaned out the dust in the back of the tv
2. all fans are working
3. replaced power supply (BP44-01001A)--same symptoms
4. inspected all boards for blown/bulging capacitors, etc--no deformities
5. tested all LCD's with a 9 volt battery--all are working
6. Called Samsung...some things are better left unsaid

Is there anything else I need to test? Should I go into the service mode and run diagnostics? Am I able when the picture is out? Is my Samsung now a big paperweight?

I am too cheap to spend money on taking it to the shop, besides, I think I can fix it myself and I love working with electronics.

Thanks in advance for your help. These threads are really good and helpful, however, I have not found a solution to my problem.

Be warned, you'll likely spend more money utilizing this methodology.

I do realize that there will be a time when I may take it in the shop, 120inna55. I just want to see if I can fix it myself. Who knows, there may be an easy remedy to fix my TV.

Are there any thoughts about what might be wrong with my TV?

14 months and 4384 hours later and my replacement lamp from advanced lamps died very suddenly. It was working fine last night, went to power it on this morning and it was very very dim followed by it powering it self off with the 3 front lights blinking. Installed the oem bulb with 15k plus hrs on it and now it works fine. Guess its time to get another one, too bad it didnt last very long.
