Hi Everyone:

My Samsung HLS-7178 is a little over a month old and I am noticing a very weird problem. Every now and then I get one, two or three white bars of light, a couple of inches in size, which run down the screen vertically about 1/3 of the way from the left side of the screen or sometimes down the middle. It almost looks like a reflection of light (but it is not as it appears with all lights off). The problem appears very sporadically and does not depend on what is on the screen (blacks, colors, HD, SD, etc.). The bars stay for a few seconds and then disappear. Sometimes they will not appear at all during a show and sometimes they will. Sometimes they will repeat on the same day, other times they will not appear for days. It almost looks like there is a light leakage from the edge of the screen. It kind of looks like the vertical light you would see if say you shined a flashlight into your camcorder. You can really see it if you have a scene with adark background and a view of a candle or light source. But it can be seen in other scenes as well (light and dark). Weird problem...anyone else have it or know of it? Is this an overscan issue?

I do have Eliab coming to calibrate during his Florida tour in the beginning of March. I think this may be just an adjustment problem, but I think I may need to address it before he comes(?)

Thanks in advance.

Thanks in advance.

Ask Eliab. You don't want to calibrate a set that may need repair. Have you tried to get a picture of it?

I just ordered a HL-S7178W from Broadway Photo.
Like most NY companies I knew they would try to sell me something more.
Sure enough they sent an email asking me to call to "confirm the order"
So I did, and sure enough the dude starts off slow, but soon, he asking about cables, stands, warranties. And then, it came, "how about the lamp, did you order the lamp". I said it comes with one. He said "I have never heard of that"
He referred to the lamp as an accessory, as if it were optional.
Perhaps he was ignorant, or maybe he was a scum bag. I know if my elderly mother had made that call, she would have been tricked into the lamp.

Was it one of those "Leg Lamps" from Christmas Story? I want one of those.



Was he selling an additional "backup" lamp or making you think the set comes without any lamp at all (which would be ridiculous).

When I said it came with a lamp, he said, "I have never heard of that, have you confirmed with the manufacturer that is comes with a lamp".
So there was no doubt, he was trying to trick me into buying a lamp under the premise that the unit did not come with one.

Eliab just finished calibrating my HLS7178 a few hours ago. Since then I've been watching just anything and everything HD, and playing as much Xbox 360 as possible.

It's been said before, and I will say it again: If you are on the fence about getting a calibration, it is VERY much worth the cost and I would highly recommend Eliab for the job.

Prior to the calibration, I had done all of the user level/forum recommended SM tweaks on my own ... and I thought I had done a pretty good job of improving my image (who knows, maybe I did). It does not hold a candle to what my display is doing now. Everything is mch crisper and cleaner (my focus was way off), there is a fraction of the noise in the picture that there was previously, the colors are spot-on (and not 'screaming' at me anymore), and details exist in the picture that I simply had never seen before. I'm truly amazed at what the set can do now.

Eliab himself was outstanding, providing blow-by-blow analysis of what he was doing, what the equipment he used was doing, why certain changes were being made, and stopping to point out what a specific changes were doing to the picture on numerous occassions. It was quite the education, and he was a fantastic teacher!

So, my executive summary is this: It was well worth the money, Eliab is a great guy, and is great at what he does. Highly, highly recommended!!

What specifically do they do? Is it just adjustments to the same controls you can adjust, or do they pull the screen off and physically align and adjust lens, wheels, etc?

The main thing a professional calibrator will do is use test equipment, training, and experience along with a little talent to adjust the complex variables available in the service menu (SM). We can also get into the SM, but the changes we might make are of little help.

The kinds of physical things that were done to improve CRT RPTV PQ are mostly not possible or needed on digital sets. The lens focus can be corrected without taking the screen off.

What sort of equipment?
post #1122 of 1718
Thanks for all the great info in this thread guys. I've made up my mind to go with this set for my bonus room HT after reading through it.
Cheers

Sounds good! It's a great choice.

I am also interested in this set. I can't stand watching blu-ray/hd dvd on a 720p set any more! :-)

I remember reading somewhere in this long thread something about sets with December 2006 build date having some sort of design difference from earlier built sets. Can anyone enlightent me on this? And also, does anyone know when these sets will become available for purchase? (I can wait a couple of months if necessary.)

The "difference" that you can't recall is already present in the models that end with "88", "79", and "78" so it's a non-issue. For these sets "overscan" can be turned off in the service menu already.

It appears that Samsung changed the SM for "87" models and for those sets it is now possible to turn off "overscan" and have the new setting stick.

We don't know what the new 2007 models will be like until new owners report here at AVS.

Here is a link to the discussion that you are remembering.

A different SM for "87" December built sets?
post #1126 of 1718
Thanks for the feedback. So my understanding is that there is no new firmware for this particular set, right?

I also came across this when looking back at this thread.

This was my one big question mark over whether to purchase this set, but hopefully, Samsung has now made a change to fix this on a more permanent basis.

Thanks for the remarks on overscan--I'll try to find the instructions for this and turn this off on my set as well .

So, as I understand, this set has history of issues such as 'collapsing light tunnels', service menu settings being reset when the set loses power or someone goes into service menu, dnie turning on by itself.... I'd like to buy it, but it kind of makes me nervous, considering the money that it costs.

If there has been a change in firmware for these models we don't know about it.

Here is my understanding based on reading HLS threads.

I don't know if a HL-S7178 has been reported to have a shadow caused by a "collapsing light tunnel" in this thread, but it hasn't been reported in the thread dedicated to the problem. Most of the HLS sets reported have been "87" models with a couple of "88" models showing up. That doesn't mean that it couldn't happen, but only that there are no reports at this time. Far fewer HL-S7178 models have been sold. The total reports in the shadow thread for two model years (HLR and HLS) is about 60 at this point in time. I'm sure Samsung has sold several hundred thousand sets in that two year period.

service menu settings being reset when the set loses power or someone goes into service menu

User Menu settings are, by design, reset to default values whenever the SM is entered. That's true of all HLS models. I don't recall the exact incident that you are referring to, but I expect that it was a rare occurence. I read all the Samsung 1080p DLP HLS threads and I don't recall it being a problem for HLS sets in general.

Quote:


dnie turning on by itself....

I don't recall this one either as a "problem" for HLS sets. If it was a common failure it should be showing up in the main ("87" and "88") owner's thread.

The shadow (light tunnel) problem is serious, but all indications are that Samsung is taking care of it. It's the only problem that has generated it's own thread.

Shadow Thread Summary

Samsung DLP sets seem to have more owners that report being bothered by pincushion bowing of 4x3 images than other RPTV brands. The bowing has to be greater than 1/4" for Samsung to take action.

Samsung DLP sets have had some power supply noise that can be heard when the set is in standby mode. It's an easy repair under warranty.

I skipped the HLM and HLN models because I felt like you do now. Anyone who buys any of these microchip technology sets, and doesn't live close to a good service provider may have a hard time if they need repairs. That is a situation that contributes a lot of the horror stories that you find in owner's threads regardless of the brand name.

It was my set that does this. When I lose power or just go into the service menu, its completely reset to factory settings (sm AND um). It sucks.

David from Avical witnessed it and said he hasnt seen this before. Mine is the only one that I know of.

Since I cant necessarily contact Samsung with this "problem" (since we really arent supposed to be in the service menu), I have to live with it.

Luckily, I have a UPS backup and a spreadsheet with the settings just in case. No problems so far. Ive learned to live with my memory challenged set.

Damn. I am very afraid to unplug mine now (not that I have reason to, but just because this is coming up I'm sure I'll have a power failure tonight)!!
post #1130 of 1718
I had the light engine collapse (so I was told). They replaced it with a new one and new lamp..... bonus for me.

I purchased a battery backup to protect the set. This is a great idea if you want to protect it from surges, brownouts, and power outages and would solve the settings issue in most cases.
post #1131 of 1718
Hi, guys,

Thanks for the feedback.

Regarding dnie turning on by itself, I distinctly remember in this thread that Eliab recommended that when you do critical viewing, to turn off and on dnie, and turn brightness one notch up and then down, or something like that. Is anyone actually doing that?

So it sounds that as long you have ups and you don't go into service menu, you should be ok, right? rockstrongo, what ups do you recommend?

Also, how bad is the pincushion effect on the 4:3 material. I watch a lot of old, academy ratio movies, so it's important. I currently have hlp6163, and while the pincushion is noticeable when I look at the corners, I can't honestly say that it spoils the movie watching for me. Are the hls sets worse than the hlp sets in that regard?

I recommend that you have your calibrationist check the service menu issue before doing the calibration. That way, you know whether your set has the same issue. Maybe its just my set, but it could possibly be a bad batch of these sets.

As for a UPS, they make some specifically for home theaters, but I just went with an APC brand one from the computer department at Best Buy. I only have my TV connected so it would last a couple hours (with the set turned off). I believe my ups was about $150 on sale at BB.

Thanks for posting again. Are you aware of anyone else posting about this problem? My impression is that it's the first time in five years that I've heard of it.

You could get hit by lightning too.

So far, if we trust my failing memory, it's a one of a kind report spanning the HLM, HLN, HLP, HLR and HLS models.

Can you report your "tunnel" fix in the shadow thread so I can include it in the tally that I'm maintaining. Include your model TV as well. Thanks.

I dont know of anyone else with this issue and David said he hasnt seen this. Maybe he has seen this since I last talked to him? Im not sure. Im worried that some others may just not have noticed since they dont go into the service menu or havent lost power.

Or, I might be the only one. But, I love my set and honestly wouldnt trade it. Even with its handicaps. It performs well.

Now that I'm thinking about it, Eliab unplugged the set completely when we removed the base on my set (which was after all calibration had been finished), and nothing bad happened. Yay!

Wouldn't those who never make changes in the SM have nothing to worry about?

If there were many sets with this problem it should show up at AVS. This is the SM capital of the Internet.

My former TV was a HL-P6163 (Which was replaced with a HL-S6188) and now a HL-S7178. The 7178 is no worse that the HL-P6163. The HL-S6188 was the worse of the lot. I made comment some time ago on the main thread some time ago that the "pincushion" problems are nothing compared to the early flatscreen computer monitors (14") They were adjustment nightmares.

Well, it happens not only when I go into the SM, but also lose power. Im sure the latter is more common.

David and I tested this when he was at my apartment. I had just noticed that it reset when I lost power (when I was moving components around). He actually played around with it and noticed it did the same thing with he went back into the SM.

I agree that if this was a problem for others, it would have most likely come up here. Mine seems to be the oddity.
