55" Samsung LED TV (UN55D6300SF) cracking open: Box
The edge-lit Samsung UN55D6300SFHP 55" LED TV gives you a big screen, Internet connectivity, apps, and an integrated Web browser.
I wanted to see how Samsung packed all this tech inside a TV that's just over 1" thick. So, I got out my Phillips screw driver and popped off the back cover. Follow along as I crack open the Samsung UN55D6300SF.
As this photo shows, the TV's box was too large to fit within our studio's normal shooting area.

for the pics and info. I treated myself to a 46" 8000 for christmas and the picture quality is stunning. The 3d effects are also stunning, particularly yhr film of Cologne Cathedarl from above - the spires come out of the screen and you feel you can touch them. The Samsung really is a fantastic TV.
I am just curious what you do with everything you tear down? Are they used in the office or returned, etc? I also would like to see more of this TV torn down, but am thankful to see it go this far. It's an excellent peice of entertainment.
why is the power supply board so big, what was the ratings on that board? does it do 120-240V 50\60hz? any idea on the part name for the board? iam looking at replacing the power supply n my samsung un46d8000 which has 120V 60hz into 240v 50hz compatible version.
It's not hard to remove the LED edge lighting unit & pull apart the diffuser & silver back panel. The reassembly is straight forward, you will need quite a bit of care to assemble it tidily, but it will still work fine. Personally, I would use the smallest unit as they are all the similar inside (from each manufacturer). I'm fortunate as we have hundreds at work, we cannibalise one to fix several as many parts often cost more than a complete new unit.
Great TV - haven't learned to use it all. Remote sensor is bottom right in the black glass near the red power light - look closely for density difference in glass. Mine is 3d - not wanted but came with it anyway so might as well. USB can be plugged in to record TV shows as required - lots of inputs etc - LED gives beautiful colours and contrasts Would recommend - was lucky to get a good price of eBay - manufacturer refurbished...
While I too would like to see a bit more of this deconstruction, I can appreciate Bill's reluctance to demolition it, rather than demonstrate it. If there's that much interest, then anti-up. How about 20$ each & then I guess he would/should-N'T have any real reason not to "git er dun"! jim jmk-nbsc
A friend (Alan R. M.) bought a smaller model he uses as a monitor, but when he changes channels on his big TV the monitor changes too. He cvan't find where to 'mask' the sensor to avoid this behavior. Disappointed you didn't indicate where the sensor is...
Why couldn't you do something as simple as a google search on the chip numbers and report what these chips are desinged to do, rather than just reporting the markings on the chips?
I have written about using LED's to upgrade older screens on my blog at bobdavis321.blogspot.com under LCD monitor repair. The results were not that great, you need a diffuser to get even lighting from LED's.
Gregg Reber was disappointed that you never pictured the EDGE LIGHTING area of the TV where the LEDs are used. Like the florescent tubes were used, now are LED.
Thanks for this tear down. I was also disappointed that you stopped where you did. I enjoy "cracks" that go so far that you mention that you are relieved that the item still works after it was put back together.
I also among others was curious to see the LED screen. But overall I appreciate your efforts and time.
Having just bought a Samsung 32D6000 this satisfied my curiosity. OK you could disassemble the LED lighting - but that is not that complex is it? The speakers are interesting being flat - so maybe one day. But I don't think it is necessary to pull all components apart in these articles. Maybe a separate article about LED lighting technologies - comparing the different types? Also maybe a separate article on the new speaker types used in flat panels? Thanks again.
hmmm this is a great help to me i recently accepted a job to repair a samsung lcd tv ...and helps me opening it and repair it.... a shorted diode in the power supply
I just spent 10 minutes looking at pictures of you removing a cover and a couple boards to show the primary driver chips? Nothing about the LED lighting, the speaker assemblies or anything deeper than the 2nd-3rd layer? Disappointed not only in the "tear-down", but the technology that makes a screen so large I can see the actual pixels. I know, that's not your department.
Ok, that was a trivial and disapointing cracking open. That's like cracking open the latest hot car by showing us the inside of the glove box and trunk. We want to see what's under the hood! Show us the LED light source and LCD sandwich module in operation while it is dissasembled.
I have a Toshiba (DLP), an old Viewsonic LCD & 2 Vizion LCD (refurbished) HD TVs, myself. I have pass the info along to my friend with the multiple Samsungs.
OSRAM Micro SIDELED I purchased a few dozen of these for a model lighting project, damn small 0.8mm, but bright. http://catalog.osram-os.com/catalogue/catalogue.do?act=showBookmark&favOid=000000000002602900090023
Thanks for the offer to bankroll out dissection of an LED TV. It's just one example of why TechRepublic has the best members. Luckily, I should have enough money to purchase either a small unit or one that's been refurbished.
From my observations, the most likely location for the remote IR sensor is the lower-right corner (when facing the screen) next to the front control panel. There's a small PCB (shown in pic 16 - http://www.techrepublic.com/photos/cracking-open-the-55-samsung-led-tv-un55d6300sf/6241051?seq=16) mounted just below the right speaker. As it's the only PCB that I saw mounted to the TV's bezel, it likely has the IR receiver.
Well if it that simple then you do it. Bill here is doing what the majority of us wouldn't dare or have the $$ to do. If you can do it better then do it and post your link.
Did you perform and Internet search on the chips that don't have detailed descriptions? If you do, you'll find that the search returns no, or very limited results. Yes. I "Google" every single chip I shoot a photo of. Unfortunately, not every manufacturer posts detailed information on their chips. And even those that do, may not list chips that are made specifically for a single company. If I only list a chips markings, it's because I spent 10 minutes searching for a description and came up empty.
My goal is to disassembled devices in a way that allows them to be reassembled in working order. Dissecting the LCD/LED display assembly would likely destroy the unit.
if i where close to u ill give u all my junk lcd screen that i replace so u can look at it first hand.....basically the light source of un lcd screen is a flourocent sandwich in between the led and the back reflective plate ...which produce the white or may i say blue light
I stopped where I did to avoid damaging the LCD display assembly. As others have pointed out below, "LED" TVs, like the UN55D6300SF, use LCD displays and LED light sources. In edge-lit models the LEDs are mounted along the edges behind the display but inside the assembly. Removing the metal backing from the LCD/LED display assembly involves a high probability of damaging the unit. My goal is always to disassembled these devices in a manner that allows them to be reassembled in working order. However, there seems to be an interest in seeing the LED light sources on and LCD/LED TV. What would you say if I purchased a slightly cheaper LED television and dissembled the display assembly on that one?
That was a bit of a waste of time, can you show us what makes this tv different from others, basically all flat-screen's look like that if you just remove the shell.
My Phillips 40" is right in the same area as the power light, center bottom. I easily determined this because my Sony HTS center speaker, as small as it is, just blocks the IR sensor.
I'm from Samsung and have noted your tampering with our product so I have to inform you that this has been noted and the Warranty Terminated. ;) Now what this about actually buying the unit and not pulling apart a loaner from the maker's Country Agent? Of course if you where in AU as the end user pulling it apart to see what???s inside it would be OK as that is covered by AU Law and allows you to do things like this. :D Col
Was really disappointed when I first learned that the LEDs were only serving as backlighting. I'd like to know the variation of the pixel intensity due to the LEDs being so much closer to some pixels than to others.
