Just what's inside a Sammy 'S' 1080 DLP?

post #1 of 146

Thread Starter 
It's been two years since I did my first "What's Inside" thread;

http://www.avsforum.com/avs-vb/showthread.php?t=403136

So I figured it was about time to cover the 1080p 'xx87' & 'xx88' models. These excerts are from the SM of the HLS-5087W, but should also cover the xx88 models. The major differences being the addition of the QAM tuner & 1394 ports in the xx88 over the xx87.
This should also cover much of the xx79 LED models other than the light source (lamp & ballast vs LED) and the lack of the color wheel.

I was surprised with all the additional control settings accessible from the menu. Settings that are well beyond this thread and should be beyond just about all who want to venture through them. This brings me to the usual warning;

1. If you don't know what you are doing, DON'T DO IT!
2. Write down ALL setting numbers first on each screen as they might be different that what is shown in the SM.
(Best is to take screen shots of each screen.)

Here is a convenient reference list for excerpts from the Owners thread;
http://www.avsforum.com/avs-vb/showt...97#post7975797

Attached are two of the 'features' tables. Notice the reference to the DLP chip as a "xHD5"! Also notice the 10 bit processing mentioned. One of the differences between the '87' & the '88' was the 10 bit processing, or so I was told.
Note the nickname of the CPU processor; "Albatross" and the addition of a USB port for S/W upgrades and JPEG & mp3 files.

In the "Analysis" (not shown), the major differences between the 'R' and the 'S' series are; brightness; 600 vs 800 cd/m2, the DMD chip; xHD5 vs XHD4, the addition of "Wiselink" USB port and the elimination of the 2-tuner split screen PIP.;

Please understand between the Forums' size limits of the attachments and the PDF files themselves, I have to split up many of the .pdf pages to fit within the 800x600 size limit and still be readable. If you are expecting a full page hi-rez image, forget it. You can always actually buy the SM, but most of what's important, I feel I have included here.

Now, for the meat & potatoes, the Service Menu. Please be warned. There are far too many adjustments that WILL get you in trouble if you mess with them without writing the orginal setting down first. In many cases that still might not be enough since the possibility the set could loose lock and you won't be able to recover!;

Tilt adjustment.
There is a safety interlock switch on the base around the DMD fan that will remove power from the unit when the back is removed.
That has to be temporary defeated.;

I do remember a lengthly discussion regarding the unpopular DNIe and a way to turn it off in the SM. I also remember the early finding would only turn it off while the set was left on. If you power it down and back up it would revert to the 'on' state. Later posts reported it could be permanently turned off. I came across this post, but I don't know if this is the corrected procedure or not;

The 2nd attachment describes the adjustment headings later on in the thread;

These features and descriptions do appear to confirm the 10-bit processing for the xx87. S5H2201, SDP51, SDP52 chips, which the comparison chart shows as 10-bit input, 10-bit output.

I believe BOTH sets have it, but it could be de-rated (if that is possible) in the 87.

It's called marketing.

Great thread!
Looking at these 'Block-Diagrams', you can see that HDMI SPDIF 5.1 is downmixed to 2-channel audio.

Here is the flow of the HDMI Audio:
HDMI Cable -> MST3369 HDMI Receiver -> SPDIF Audio -> Albatross (S5H2201) -> PCM1754 (Digital to Analog Audio Converter) -> STV8256 (Digital Audio Processor) -> SPDIF Output

The PCM1754 chip takes the I2S Digital Audio and converts it to 2-Channel Analog Audio. The chip does not seem to support Dolby Digital Decoding, which means the Albatross decodes the signal and downmixes it to 2-Channel Digital Audio and then sends it to this chip. As you can see the ALbatross lists' AC-3 Decoding' as one of its features.

The parts seem very capable of handling HDMI 5.1 Pass through, the STV8256 supports multiple SPDIF inputs and has the pass-through capability.

ADDITIONAL OBSERVATIONS

All the options of the x88 seem to line up with this sheet. Including PiP, Firewire, Gemstar, CableCard, Subwoofer out.

Interestingly though, the x87 series diagram shows that the Cable/OTA input on the tv flows into the T313 Tuner, then outputs to the optional 'Cimax' interface which works with the cablecard. Without the 'Cimax' interface option enabled, the T313 Tuner should/will send the Transport Stream (TS) directly to the Albatross+ chip.
The 'Cimax' chip does NOT do QAM Demodulation, all it does is interface with the cablecard to decrypt the Transport Stream that is being fed to it by the T313 Tuner. This tells me that the T313 is not only a Tuner, but a Demodulator.

This means that the T313 that is featured in the xx87 and xx88 models supports QAM already. So why does the xx87 model not feature QAM Support? It must be disabled in software, which is a real shame.

EDIT: To back up my thoughts on QAM being software disabled in the xx87 models, if you look under 'Product Features', the HDTV Tuner utilizes the BroadCom QAMLink. QAMLink...

Good observation. I have updated many of the above adjustment posts with descriptiuons of each chip.

Any other comments or corrections are welcome.

I cannot find any information about the MST3369 chip, but this chip appears to be the one that enables all the 1080p inputs via HDMI, Component, and VGA. I guess they beat Silicon Image to market, but I dont know who even makes this chip? MST? Would have thought we would have heard a lot more about this chip as it seems to be an excellent all-in-one solution for DTV's.

Also, I went through the board image and tried to point out the pieces that the x87 is lacking.
I was left with 2 empty BGA locations, one of them is for the SAA7119 BGA for the Second Tuner, and I am assuming one is for the firewire PHY.

The CiMax Interface they refer to in the block diagram must be built into the cablecard because there does not appear to be a location on the board for it.

Does the tilt adjustment adjust for pincushion? I have pretty bad pincushion on my HL-S6767W and would love to fix it without a service call.

No, not as far as I know. There shouldn't be a need for pincushion.

Is this on 4x3 material? If it is, that is a common problem with many Microdisplays. The side 'bow' inward towards the center when watching a 4x3 image.
