Seiki SE50UY04 3840x2160 50" TV ($1300)

Are you Red or Green? Green, it's in the control panel for custom resolutions.
As for Red, I've ALWAYS had a hell of a time making it work. You need a pixel patch to the AMD drivers that unlocks over 300Mhz and use CRU. Dealing with this pissed me off so much I pretty much never will use AMD again because it can't get it's shit together with 4k and hamstringing their drivers constantly.

You're right! This is the best one for 4k for sure, it makes 30hz feel like 50hz, nice!

I changed to that firmware, and somehow now 120hz is gone even tho it's still set in CRU.
With this firmware, it forces 1080p to be under the 300MHz clock just like everything above 1080p. Weird, why can't I get 120hz to work with this firmware?? Max is 103Hz, which is 298.87MHz. :\

How can I go over 300MHz?????? Any resolution
I thought this firmware (ATSC_THTF_SY14343_ST2975C_CMI_V500dk1_P01_20140707) unlocks the clock???

Sadly I did write the firmware does unlock the clocks, I was wrong..
It was that I just switched over to a Nvidia Card and they are not locked.
I spoke to ToastyX and he updated his patch on my request

his old patch fixed a DVI limit and another HDMI limitation,
he updated it to unlock the 297Mhz Locked Pixel CLock..

Good news tho, ToastyX created a file for AMD that unlocks this clock, and I did it and it works..

Solid work there, m8.

We need to get all this info on one post.
 
i suggest waiting for 4:4:4 support to be confirmed before jumping on this quasar 4:2:2 or 4:2:0 is useless for monitor usage

We may have a new 4K TV/monitor contender.. Quasar 42" w/ HDMI 2.0 doing 60hz. Just ordered one.. time to unload my Seiki 39.

For as much talk I hear about this display, I've yet to see ANY user provide concise info other than they have been able to take up to 80hz @ 1440p and 1080p. Also it does not have display port. So if you got AMD your sol.

No words if it's 4:4:4 or even what kind of scaling it does.

as i am digging the net in search of a reliable board replacement, i finally found high resolution pictures of the Skyworth 39E780U internals.
...
what are the chances that Frankenstein build using the panel/t-con and led driver of the Seiki succeeds?
Click to expand...

I'm wondering about that. My reasons are different - the European version(s) of the Seiki have an even worse input board than the US version (SD-only DVB-T tuner, SCART socket, laggy, no replacement firmware) and I'm wondering if it's possible to board swap with another version.

One thing I note is the LVDS wiring is different from the US input board and the Skyworth boards (I haven't found a picture of the EU version). Most of the loom looks different. So it would need new cables. You might end up having to replace quite a bit. One thing to note: it may be the power supply is different because the Skyworth is 220V and the US Seiki is 110V, so it may be that replacing this isn't necessary - the main question is if the pinouts are the same. My instinct is that it ought to work, given there's no flash or anything in the TCON that might need reprogramming. But there could be unexpected glitches.

What was your source of parts - Taobao or somewhere else?
 
Further digging indicates that the European versions probably use the MSD309 mainboard chip from MStar Semiconductor (now Mediatek). This is an HD-only chip which would explain why it downscales everything except UHD to 1920x1080. There seem to be at least MSD309B and MSD309P versions out there - I don't know the difference.

Skyworth have service manuals with schematics of other models using this chip, for instance this TV (with an extra ISDB-T decoder for Brazil):
http://www.iskyworth.com/UpLoadFiles/20140208/2014020811454644.PDF

The next question is... if this chip doesn't do UHD how does it manage to passthrough UHD inputs, and how does it manage to do OSD on top of the UHD content?

On the subject of Frankenstein mods, for those who want it for a monitor how about swapping out boards with one of the UHD models on sale? For instance:
http://www.ebay.com/itm/GENUINE-ASUS-PB287Q-Main-Board-715G6681-M02-000-005I-/181660638693
http://www.ebay.co.uk/itm/New-In-A-Box-Samsung-LU28D590DS-ZA-Main-Board-BN9112453K-BN94-07403Q-/
Questions are: is the panel signalling format the same, is it just a dumb panel or something cleverer than that, what are the pinouts of the mainboard, and how is the backlight controlled?

changing boards with other UHD monitors does not work: IPS and TN signal and voltages do not match the VA panel from chimei-innolux that is used on the Seiki. For a franken build to suceed it would most likely need a board designed to work with the same panel, like the one from the skyworth

TB1NpRcHXXXXXc8XVXXXXXXXXXX_!!0-item_pic.jpg
 
comparing TVs:
power board are not equal
main boards are not equal
led driver boards are equal
tcon boards are equal

skyworth is capable of 41Hz+ operation at 4k, plus it has a card reader and does 3d out of the box.

pin wise video connector are rotated 90 degrees between main boards, and power plugs are not compatible 1:1, so when changing main board one should likely change power boards as well.

all i need is someone with more knowledge to study the pictures and tell me to pull the trigger on the skyworth spare parts for my franken build
 
I just picked up a se39uy04-1 any tips on things I should change in the setup? I checked the firmware and it came with version 277 from Sept 3/2014. Any tips on settings would be much appreciated.
 
Grats on your new TV MrWrong.

i spend a few dollars on a basic hardware color calibrator, a spyder eXpress. it basically transformed my so-so TV on a $3000 pro monitor, at least for sRGB, which is basically all the games i play and all the net i surf.. a good place to star a manual calibration is

Warning: this post is picture heavy...

Geok1ng, this is my guess at how things are laid out:

skyworth-annot1.png


The left hand side in both cases are quite sketchy - while it's possible to recognise power and USB, it's harder for random low-speed/low-power signals like buttons and so on. In theory it's possible to count pins off the pictures, but I couldn't quite make anything match up.

To recap, the other boards from the Skyworth we need to worry about are timing controller (TCon):

...time passes...

Ah, the 50" looks similar:
7n7f.png


This suggests there's a second (scaler?) board that plugs into the top of the main board, and from there there's a flat cable going into the TCon. I can't seem to find any pictures of this for 39" or 50". Perhaps the twisted pair cables I found a picture for above suggest than the 39" doesn't use this board?

Edit: found a better picture
42C818AC16D408C7B2552E891210D391.png

That source (linked earlier in this thread) says the processor board is a Mediatek MT5326ACDJ CPU plus a Novatek 72314. I've yet to look these up, but that seems some quite serious scaler action which isn't present on other models.

this is the most amazing progress this thread has made over the last months.
i do not have acess to an open skyworth TV, but Seiki is showing its innards on the tech repair and i will dissect every connector and pins on the left side, with VERY high resolution pictures.

About the mysterious board that appears above the main board on the 50" skyworth photo, i have noticed it before and been unable to locate the spare part number on taobao or alibaba.

at any moment there will surface pictures of the innards of the new seiki 40" DP monitor, which may be using the same panel. sure it will be months before such boards appear on ebay/taobao, but unlike myself, most readers of this thread have working TVs and can wait.

It appears the Novatek NT72314 is a MEMC (motion estimation/motion compensation) chip. So maybe we don't need that secondary board. Though there appear to be two chips on there (both with 2x DDR RAMs). It rather depends if the LVDS signals in and out of the board are the same format so that it can easily be removed. The existence of a cable going from mainboard direct to TCon suggests it might be feasible.
 
Paydirt. That's the service manual for the 50E780U. It's all in Chinese, of course, but just look at PDF page 54 for instance. This also tells me that the ID for the mainboard is 8K93. That should be enough to extract pinouts of the connectors.

I found an alleged source of the schematic (the magic Google phrase is '创维8K93原理图') however Weixiuzhan seems to operate a credit system so I can't download it.

I also found a schematic of a TCL board using the MT5326ACDJ for comparison.

ETA: I'll list more documents here rather than yet more postings in this thread
8K93 motherboard maintenance manual (and here), also I found a copy in Word/rar (can't remember where). Looks like better images of connectors.
MT5326-based schematics (rar) - the website says these are 8K93 but I'm not sure they are.

I also just noticed that the pins on the Seiki board are helpfully labelled on the back ;-)

So we have on the Skyworth:
CN5 (2 pins): right audio
CN6 (2 pins): left audio
JN23 (4 pins): audio channels C and D
JA7/JA8/JA9/JA10: USB
CN100: LVDS
CN1: 24V/12V/5Vsb
CN4: wifi

However I can't find a picture of the Skyworth board in high enough resolution to read the connector labels off it.
I notice there are two versions - the 5800-A8K930-0P50 which has the SD reader and the 5800-A8K930-0P40 which is missing some sockets on the left side and has an extra USB in place of the SD reader. I think the missing sockets might be audio C and D. The 0P40 is used in the Skyworth 58E560S TV so might be worth looking that up for any info.

Has anyone figured out how to get sharpness function to work past 30hz?

I can set mine to 35hz but then sharpness reverts back to 50 and text is blurry. Using the 0000 menu to adjust it has zero affect.

Also, is there a way yet to get past the artificial 300MHZ pixel clock limit?
 
i am uncovering the mysteries of the Skyworth 50".
The 50E780U uses another panel ( DUH!) and tcon.

TB1YpQgGpXXXXbmXFXXXXXXXXXX_!!0-item_pic.jpg


This tcon links the 4 ribbons cables of the 50" display, remembering the 2B OC attempts with koreans 27" 1440p monitors, one could presume that the 50" overclocks while the 39" do not.

So i went back to maarten review to triple check that his TV was indeed a 39", and it was.

double-checking the specs of the 39" panel i see no reason to doubt that it can overclock just like the 50", but i fear there is a typo on those specs, as it states " 4-ch LVDS", but this panel on uses 2 ribbon cables...so something is solved differently.

What i fear most is that the overclocking reports on the Skyworth 39e780u are limited, besides maarten, i found this one , without mention to overclock.

maarten's skyworth is reportedly broken, anyone care to contact filip vandoorne on reduser?
 
Samsung's 6xxx series and even HU7000 series are not capable of displaying 4k@60hz properly, as they use color compression to reach this fake refresh rate. Hence there is a thread here about TVs capable of 4:4:4. I am not aware of a single TV in the 39-42" range capable of 4k@60Hz 4:4:4. The smallest start at 49" like the LG 8500.

And the old seiki is in a class of its own when it comes to 1080p 120Hz VA gaming, because its factory menu allow for color by color tweaking. As a 4k 30Hz display, it only works well for videos, but as a 1080P 120Hz display, it shines for gaming, reading and working. At 1080p the Seiki is head and shoulders above the competition on its price range. 120Hz+ VA contrast + perfect color after calibration + perfect sRGB coverage.

So I played a game (in a warm room), NBA 2k15, 1080p at 120Hz, for quite a few hours straight.. The next day I turn on the screen and the picture is all messed up on the Seiki logo, then it reboots itself, and it's messed up again, it reboots again - and then it's fine. So I boot up the same game, at 120hz again, looks fine then suddenly the screen gets all messed up (a little less than the seiki logo), I freak out in my head for 3 seconds, and the screen goes back to normal... Sicne then I went back to 60hz - realizing it's the same picture and 120 won't even matter, just turn the sharpness to 0 when it switches to the 1080 60hz profile.

Don't think I wanna mess with 120hz again, maybe I'm a baby, but just sharing an experience. Running a new 970 GTX card, fyi.

Also, just to note on 50" firmware:

- ATSC_THTF_SY14343_ST2975C_CMI_V500dk1_P01_20140707
This firmware seems to be the "best" in the way 30hz 4k feels and allows 120hz 1080p. However it does not have the fix for auto timer countdown.. I can't seem to turn it off.

The firmware I used before this one ^, I *believe* it was called "SE50UY04_20130528" - does fix the countdown timer where it can be turned off, aannd it also worked better with knowing when the computer is off or on to turn itself off or not. I THINK this was the one? (Can someone confirm? I can't try for a bit- no usb stick.) Worst case I got this one confused with another firmware I tried, but I believe it's this one.

Keep updating us on the behavior of your Seiki.
I am sorry to inform you that is just the behavior of my TV when it started the random reset thing.:(
My replacement board arrived yesterday and the tech repair dude just informed that changing main boards did not solved the issue, actually made it worst.:mad:

Just to be on the safe side with your TV, try a 24AWG HDMI cable. Even if it is not the cable, such a cable is future-proof for HDMI 2.0 refresh rates.
 
Hey guys, i think i just bricked my TV, i installed the september 277 firmware linked here on the 50 inch 4k TV, and now it seems to just be stuck on a black screen. Is there anyway to unbrick it and reinstall the July 260 firmware on it. (i can't seem to access the menu)

Plug it in while holding the menu button (on the side of the tv), will auto-update from USB.
Thank God. I was freaking out when I did that too.

When your screen goes crazy and freezes in 4 parts, I never got a 4-split I only got the same noise looking thing, but other than that I got no problems like yours.. Man, doesn't look good at all.
I haven't used 120hz since, in fact deleted the setting, and been perfect since. I would try different firmware??

it is not my TV, but the behavior is the same. this problem is firmware agnostic. and just the noisy self-reset thing is enough to avoid using the TV as main desktop, but as i said, the interval between self-resets keeps shrinking until it self-resets every 2 minutes.

if this is wide spread behavior for the Seiki, i am even more inclined to try the skyworth franken build.
 
anyone been able to get chromecast to display higher than 640x480@60 on the 39 or 50?

Figured it out... Doesn't like houkouonchi's custom firmware.

"HELP" My Seiki Digital Se50uy04 50 Inch 4k the screen goes black it loses drops signal for a few seconds and the picture comes back while watching Blu-Ray movies running at 1080P it happens only once when watching at 1080P during movie..But if i use the Seiki U-Vision cable to upscale the Blu-Ray disc to 3840x2160 the screen blacks out it drops loses the signal 3 to 4 times during movie play back and the black screen seems to last 10 seconds or so before the picture comes back while using the Seiki U-Vision cable..I have used regular thick old school HDMI and new type RedMere cables for 1080P i have 8 different cables to try all with same results i have a sony Blu-Ray and a LG Blu-Ray player that i have used.I do not use this TV as a computer monitor..Thanks for any and all Help:confused:
 
You are going the right way putting your suspects on the cable, as this is typical cable behavior. continue your experiments changing HDMI ports.

I acquired a pair of 6ft 24AWG HDMI cables, so i know that any issue i found using them is not cable related.
 
Hey guys!
I've received my Seiki SE-39UY04 ---> EC <---, the european version of that thing :D

The mainboard is different and so is the PSU: the main is a Cultraview CV309H-C-13 .. I tried to search for informations about it, but it seems I can't even find it for sale anywhere.
I tried on taobao, alibaba, ebay, whatever.... nothing, it's a f*in ghost!


Anyway, since I've read the whole 94 pages thread and I like what's goin' on here, I'd like to share the photos of my TV's boards.
Upgrading this (350 euros here!) inexpensive TV to handle DP or dual-HDMI would be awesome.... I wonder why the scene is SO silent............


We practically know everything about it ;)

Btw, here are the photos: https://plus.google.com/photos/103288440559570023412/albums/6144620298207755425

If anyone needs any other photo and/or informations, just ask ;)
 
Just a heads up, don't delete any of the firmware files you have. Seiki has taken down all references to, and pre-existing .zip files from their site. So what we've got now is all we've got. Google drive, Skydrive, all that stuff.
