DLP Lamp Guide - LCD and DLP Repair Tips - Fix Your DLP - FixYourDLP.com

Hi everyone,

Here is a link to the video showing the intermittent noise problem I am experiencing with my Samsung HLS-7178 DLP.

http://video.google.com/videoplay?docid=1420583595645736954&hl=en

Descrition of problem:
The noise from the video is consistent (in duration and sound), and it happens every 6 or 7 times the set is powered up.  If it is one of those times it makes the noise at start-up, it also makes a quick “cough” at shut-down (one quick burst of the noise in the video). 

Aside from this noise, the set works/functions perfectly as far as I can tell (even during the times it makes the noise on startup, everything seems fine once the noise stops).  It appears to me that the brightness level/output may be lower when the noise happens, but I cannot be 100% sure of that.  Best Buy had sent out a very poorly trained technician at one point who thought the noise may have been the color wheel, but he disconnected the color wheel and was still able to recreate the sound.  The only way to reliably recreate the sound is to go into the Service Menu and adjust the DB Gain setting - if I do that and jog the value up/down, eventually I hear this same noise.

I think an important thing to note is that there’s no middle-ground on this noise; it either completely makes the exact same noise on start-up, or it starts up/shuts down whisper-quiet.  There’s never just “a little bit” of the noise.

This behavior started after a tech had come to fix an “image flickering” issue in November 2007; at that time, she replaced the ballast and the Dynamic Black Assembly.  The flickering went away, but this intermittent noise began. I contacted Best Buy and got a replacement lamp sent out to me to see if that was the issue, but the noise still happens with the new lamp.

My gut says this is an issue with the Dynamic Black assembly, but I want to be sure it’s that if I get someone to come out and replace it again (I really want to avoid a whole LE replacement, as the set is calibrated).

Any thoughts?

I’ve got a Samsung HLP5063W in service since January 2005 with 10,600 hours on the original lamp (smaller square lamp). About a month ago it started shutting down about 1-2 times a week. It came right back up when turned back on. This week, it’s shutting off every 20-40 minutes. It comes back up instantly when re-powered. All through-out this, the picture has been crystal clear, so I wonder if it is really the lamp that needs to be replaced.

Any thoughts would be appreciated, thanks, Bill.

Si Ud. Tiene un cierto grado tecnico o habilidad manual y es muy cuidadoso entonces reemplazar su lampara es una buena idea.

De lo contrario Lo mejor es comprar el portalamparas nuevo, ya que si se aventura a cambiar la lampara unicamente , puede entrar en un trabajo dificil y causar un daño al portalamparas o a la misma lampara.

Yesterday, I noticed that my HLP6163 started flickering a lot with colors totally off. I tried switching video inputs and I kept getting the same thing. So I turned it off, let it sit for about a half hour, and then turned it back on. I got sound but no video as the tv cycled through 3 times automatically of turning it off and on, and on each attempt I could hear the fan (or at least that’s what I think it is) struggle to turn on properly, until finally I got the dreaded 3 blinking lights. I turned it off again, only this time by pulling out the power cord as well. This morning, I plugged it back in, turned it on, and the tv cycled 3 times just like yesterday, but the faint fan noise was now a loud, distinct humm that pitched up and down. I have no idea what’s wrong. I suspect it to be the lamp, but I just got a new one put in on 8/17/07 (BP9600826A from samsungparts.com) and I’ve never heard of this loud humming noise before. From reading the posts, maybe I need to get a new fan or colorwheel as well?

Some people have been asking about the 90 warranty from the manufacturer when you buy from Discount-Merchant.com. Warranties and guarantees are to help you the consumer decide on what product is the best, and safest choice. If you’re going to drop a few hundred bucks, that product better have a warranty. Retailers know this, so they’ll do anything to make the sale, even warranty for up to 1 year or longer. I’ve talked with Ali from Discount-Merchant.com and he tells me that it’s highly unlikely that Philips lamps will go out within the first year, even the first two years. The failure rate is 3 in 10,000. That means that the lamp you get brand new should work.

And to speak to the point of longevity–well, your mileage may vary. Just like incandescent light bulbs you use for a lamp in your house, or even halogen lamps for the headlights of a truck, DLP and LCD lamps are consumable parts. The more you use them, the chances it will have to fail increases. Anyone who offers a free 1 year warranty is just trying to sell you the product, and most likely, they’re selling generic because it’s cheaper to replace. They also know that so many other things can go wrong with a television and they’ll most likely turn the customer down 11 months down the line, so once they have your money, there’s nothing you can really do. The reason we trust DM is that they’re customer service is excellent. They do stand by their product, and if there are any problems, you can give them a call and they are more than willing to help you troubleshoot. They’d rather help you fix your TV than sell you a lamp (and if fixing your TV involves selling you a lamp they’ll do that too

To end, here’s a quote from one of my favorite movies… Can anyone guess which movie this is?

Tommy: Chicken wings! Let’s think about this for a sec, Ted, why would somebody put a guarantee on a box? Hmmm, very interesting.
Ted Nelson: Go on, I’m listening.
Tommy: Here’s the way I see it, Ted. guy puts a fancy guarantee on a box ’cause he wants you to feel all warm and toasty inside.
Ted Nelson: Yeah, makes a man feel good.
Tommy: ‘Course it does. Why shouldn’t it? Ya figure you put that little box under your pillow at night, the Guarantee Fairy might come by and leave a quarter, am I right, Ted?
Ted Nelson: What’s your point?
Tommy: The point is, how do you know the fairy isn’t a crazy glue sniffer? “Building model airplanes” says the little fairy, well, we’re not buying it. He sneaks into your house once, that’s all it takes. The next thing you know, there’s money missing off the dresser and your daughter’s knocked up, I seen it a hundred times.
Ted Nelson: But why do they put a guarantee on the box?
Tommy: Because they know all they sold ya was a guaranteed piece of ****. That’s all it is, isn’t it? Hey, if you want me to take a dump in a box and mark it guaranteed, I will. I got spare time. But for now, for your customer’s sake, for your daughter’s sake, ya might wanna think about buying a quality product from me.

My samsung HLS5688w has a slight flickering on screen and I have replaced the lamp, thinking that was the problem but it only worked for a couple of months and it started again. So now I’m wondering if its the color wheel. Any feedback is appreciated

I have a 20 month old Samsung HLR5668W that makes an intermittent grinding noise that goes away when I turn off/on the set after a few minutes.

A couple of  weeks ago, except for the left vertical 20% of the screen, the rest became very dark. For the next few days, I turned off/on every time it happened and the picture came back to normal. Then eventually the problem became permanent.  Thinking it was the lamp, I replaced it, but the problem still exists.

Does it sound like the color wheel is bad? The fan perhaps? Something much worse (crossing my fingers)? Please let me know. Thanx in advance.

Tom

Anywhere fron 30 minutes to a few hours later. It just turns off without warning. I called a local repair guy and he said to replace the bulb. Does this sound right? I have the HSL 6187. Any thoughts would be appreciated.

I have a Samsung DLP 43″ HD rear projection TV.  The model number is HLN4365WX/XAC.  The bulb in the TV is failing an needs to be replaced.  The product number on it is 100 W Philips BP960024C.  I am confused with what bulb to use as a replacement.  Can you advise what bulb to use and if I can use the new samller bulb with the adapter??
