Samsung 1080p Owner's Thread --- HLSxx87W/HLSxx88W DLP Models - Page 427

proceed as follows at your own risk:

write down current picture values (contrast, brightness, etc) as you will lose them upon entering the service menu.
with tv off, to enter service menu press, Mute-1-8-2-Power on remote.
find and navigate to gamma section with arrow and enter buttons.
write down oem gamma values in case you want to change back at a later time.
change both gamma modes to 0 with arrow and enter buttons.
power tv off.
wait for lamp fan to power off.
power tv on.
change your picture values back to what you had previously.

that's it, you should notice a big difference in shadow detail now.

FYI: i'm using the settings below and i'm very satisfied with the PQ.

Gamma: 0
Digital NR - On
DNIe - Off
Mode - Movie
Contrast - 40
Brightness - 48
Sharpness - 0
Color - 40
Tint - G50/R50
Color Tone - Warm2

Is the "Gamma" the SP Actuator settings? Under that menu, there is "Actu Gain (patt 1) - 67" and "Actu Gain (Patt 2) - 67". I think I saw that somewhere, but I don't want to change it until I verify it. I should just bring both of these down to 0?

Also, just thought I'd ask.. when I went into the service mode, the TV kind of emitted a strange "buzzing" noise. Is this normal? I think it was because of the fan or color wheel spinning down... and then turning the TV back on, so it had to spin back up again. But again, is that normal? =)

Thanks!

As for the buzzing noise... that question still stands. Is it normal?

Gamma affects the gamma used for every mode except Movie mode (i.e. Standard, Custom, Dynamic).

Cinema Gamma only affects the gamma used for Movide mode.

Both should be set to 0, if you want 0 gamma for all modes. My set used 4 and 5, respectively, by default.

What you described previously (ActuGain) affects the SmoothPicture (SP) settings. SP is Samsung's term for wobbulation. Adjusting the SP settings will adjust the degree of wobbulation. These typically do not need any type of adjustment.

I'm not sure about the buzzing noise? As long as you allow the set to completely power up (~30s, full lamp brightness) and completely power down (fan off state), you are not hurting it any way.

SSE - Silk Screen Effect. This is something that can be seen on DLP TV's. Lets say you see a picture of the sky on your TV. On the white clouds, instead of them being solid white, it will look "Grainy" or "sparkly". Im not sure the technical reason for this, I think its something about the pixels moving. Google silk screen effect to find out more.

SDE - Screen Door Effect. This is something that can be seen on LCD TV's, so I dont think you need to worry about it. I could be wrong though. Hope I was of some help.

I thought the SDE was only present on LCD's?

Anyone have any ideas what could be causing this? I have e-mailed the station's engineers to see if it was something on their end, but no response yet.

Some general observations...

I haven't done any direct comparisons yet, but my "black crush" issue seems to be mostly resolved. I'm using "areyou4real's" settings at the moment (thanks!). I might tweak things a bit, but for now I'm pretty happy with them.

I have tried this on more than one new samsung and the same thing has happened.

It also can't be SDE because you have a 1080p wobulated DLP which makes it extremely hard to see any trace of the gaps (black lines) between mirrors.

See above.

Based on what you described it has to be coming from the station. But, I'm still not sure why you thought you were seeing SDE - a rectangular grid of black lines separating all the pixels on the screen.

What it turned out to be was an analog to digital converter which they use only to put 4:3 analog material onto the digital channel. The A/D converter was dropping the most important bits, causing the "special effect" I saw. He has since rebooted the converter & all is back to normal.

Amazing picture with no discernable difference from movie to movie (for the most part)(Chronicles of Riddick, King Kong, Italian Job, MI III).

Regular DVD's look amazing as well. I tested Pirates of the Caribbean 2 from console drive with component and then HD-DVD player with VGA, and there was a noticeable difference for sure.

I have seen posts similar to mine, but I had to say something.

I too think that the 360 w/ HD-DVD is awesome... assuming you're also running it over VGA to get the 1080p upconvert. I've tried it with component just for grins. I can't get it to look as good versus VGA. However, I'm curious if you or anyone else has any comments on settings you've adjusted on your xx87 for the VGA input. I notice that most typical settings are not available... but in the main "Settings" area I see there's some PC settings... anyone ever adjusted these? I've found that enabling Game mode makes a bad picture.

It happens about 1/2 the time I turn it on, and lasts anywhere from 30 mins to an hour or so, or until I turn off the TV. I have verified that I can hear the noise just when the TV is on, so it's not coming from anything else.

Just to describe the problem one more time, when I turn the TV on - after about a minute or two I start to hear a high pitched whining sound. It's not very loud, but it's loud enough to be annoying. It's almost like a ringing sound in the ears. If I turn the TV off, the sound stops. - Unfortunately it doesn't happen all the time, just about 1/2 the time.

So - I called Samsung last week, and the tech which was extremely nice and willing to help said that it sounds like one of the more common issues which people experience; a faulty power supply. That is the exact same thing that you guys told me on this forum a few weeks ago. He went ahead and forwarded all my information to my local repair center which called me last week.

The guy came out today just to take a look at the problem. Unfortunately, I couldn't be home, but someone else was there for me. - They turned the TV on, and didn't hear anything. He tried for about 5-10 more minutes before calling me to tell me that the TV didn't find an issue. - So he gave me two choices

1: He could take the TV to the office and open it up and run it there. He would have it for a week or so
2: Do nothing and wait until something fails.

I was unhappy with both of those choices. I asked if I could schedule another appointment for a time which I would be available in person, and he said that it probably wouldn't be possible. I understand that they don't want to keep coming out, but I know that there is some kind of a problem - and that chances are he'd hear it if the spent just a little more time trying.

So what should I do? Does this problem still sound like a power supply issue? He said that a high pitch sound could be the power supply or the color wheel - Any ideas?

I am thinking of just calling Samsung back and seeing if there is anything they can do...

EDIT: I have the Samsung HL-S5087W - It's about 5 weeks old, I first heard the sound a few days after getting it.

Thanks!

I was also considering the 360 HD-DVD player, but if it will upconvert up to 1080p, I may go for it (plus a VGA cable) rather than also buying a new DVD player. Of course, I have my doubts if it would look as good as the Oppo... I've been very pleased with it, even going up to 1080i.

Please note: admittedly, I have no basis for comparison b/w the 360 and upconverting DVD players.

If anyone would like to send me an upconverting DVD player so that I may run some tests and get some perspective, please feel free.

I only hear the high pitched sound when I first turn the TV on for the first 30 mins to an hour or so.

I really don't want them to take it for a week to "test" it, especially since I know they are fragile and can be damaged during transport, especially without the original box which it was safely secured into.
