SPSN and SPSTV— Growing Your Way!

Karen Tillery
Service Marketing, Senior Staff

SPSN, the Samsung Product Support Net­work, is happy to be a growing part of the
Samsung CSD team! Last year, SPSN
created 345 instructional How To videos
for consumers and 104 weekly Live Shows
for SPSTV. These shows provided in­depth knowledge about Samsung products
with LIVE customer feedback and support.
SPSN also produced 78 live training epi­sodes and 38 internal How To videos, all
aimed at helping you resolve support is­sues quickly and effectively.

2011 will be even busier. In March, SPSN
developed consumer videos for Smart Hub

TV, the Q10 HD Camcorder, SH100 Digital
Camera, and several smartphone videos.
Also, on March 17th, we debuted season 2
of our live show, Keep It Simple!

We look forward to providing you with the
on-line video content you need to handle
customer product problems and concerns.
Check out our library of videos at

www.samsung.com/spsn and send your

suggestions, requests, and feedback to

How to Submit Tickets to Tech Support for Review Efficiently

Jorge Tavora

Product Support Manager/Tech Support Hotline/NAHQ Triage

Tech support receives many tickets for review and some have nothing to do with Tech Support. This causes delays for
servicers who submit tickets for technical support or exchange requests.

If you have a part issue such as “parts back order or “part not in stock”, do not choose “Tech Support needed”. Instead,

choose “Parts back ordered/not available”.

On the other hand, if you have a unit that you feel cannot be repaired or you need more Technical Support, choose
“Tech Support needed” in the Reason choices.

When submitting for technical support or an exchange request, make sure to include the following:

 Symptom details as you saw them
 The parts you replaced
 Pictures (if it’s a video problem or there is physical damage)
 The repair start date
 The number of trips you made to the customer’s home
 Your telephone number

This can help Tech Support process your request faster and avoid unnecessary delays.

The UNXXC9000 Power Up Sequence

Juan Morales
Assistant Manager, Regional Technical Trainer

To help you troubleshoot the UNXXC9000, here is the power up sequence:

1. When the AC cord is plugged in, the voltage on the STBY pin goes to 5.3VDC.

2. The Micro on the Main PCB actively looks for the user to press Power.

3. When a user presses Power, the Micro sends a “High” voltage (0-1.2VDC transition) to the SMPS via the Power_On/
Off pin to activate the rest of the voltages.

4. After the 0-1.2VDC transition on the Power_On/Off pin, the following voltages are activated on CNM801 and the
“Melody” plays.

a. Vamp ≈ 18VDC
b. OD_On/Off ≈ 3.3VDC
c. D5.3V ≈ 5VDC
d. D12V ≈ 13VDC

5. Approximately two seconds later, 5VDC is applied to the
BLU_On/Off pin.

6. Once the BLU_On/Off pin is activated, the LED arrays turn
on. CNL801 supplies high voltage to the LED arrays. The
following voltages are activated on CNL801 (with respect to
chassis GND):

a. BOT1+ ≈ 170VDC
b. BOT1 - ≈ 45VDC

Page 10

Volume 5, Issue 4 Consumer Electronics Newsletter Samsung Tech Talk

The UNXXC9000 Power Up Sequence

Continued

c. TOP 1- ≈ 45VDC
d. TOP1+ ≈ 170VDC
e. TOP2+ ≈ 170VDC
f. TOP2- ≈ 45VDC
g. BOT2- ≈ 45VDC
h. BOT2+ ≈ 170VDC

8. High voltage is applied to the panel LED arrays though connectors CN401
and CN402

 Pins 1 and 12

 Approx. 170VDC (when referenced to chassis GND).
 Voltage varies when referenced to connector GND.

 Pins 6 and 7

 GND (effective).
 Approx. 45VDC when the backlight is lowest.

 GND Pins

 GND Potential is highest when signal is >90% duty cycle (almost

DC).

 GND Potential is lowest when signal is <10% duty cycle (almost

GND).

 Level is controlled by the Main PCB though the Bot_Dim and Top_Dim pins on connector CNM801.

New: the World’s Slimmest Blu-Ray Player

Jeff Brutman

Publications

Introducing Samsung’s new BD-D7500. At just .9 inches high, the BD-D7500 is the world’s slimmest Blu-ray player. But
slimness is definitely not the whole story. The BD-D7500 is a full-featured player offering full-fledged 3D playback for

your 3D discs and Samsung’ s innovative 3D Converter technology which delivers exceptional 3D conversion of movies,

pictures, and streaming video at the touch of a button.
There’s more, of course. Along with all other 2011 Samsung Blu-ray players, the BD-D7500 offers Samsung’s AllShare

application built in. AllShare makes it easy for you to share multimedia content – videos, images, music and more – be­tween DLNA-enabled devices such as PCs, cameras, tablets, and mobile phones. Once connected to your home net­work, the BD-D7500 can easily play back content located on other AllShare devices. To make it easy for you to connect
to your home network, the BD-D7500 has built-in WI-Fi and offers Samsung’s new patented One Foot Connection fea-

ture. When paired with Samsung’s wireless router (the CY-SWR1100), it provides easy, hassle-free network connection

set-up. You simply place the Blu-ray player within one foot of the router and push one button to establish a connection.

The player will then maintain this connection regardless of where it’s placed in the home.
Once you’ve connected the BD-D7500 to your home network, you can use its new Smart Hub feature to access the

Internet. On the net, you can visit Samsung Apps, the world’s first HDTV-based application store, with more than 200

apps to download in the U.S. If movies are your thing, you can use the Your Video application to preview and watch vid­eos through a personalized recommendation service. If you want other content, you can use the Smart Hub Search func­tion to find music, games, and more.

The BD-D7500 also offers built-in support for Dolby True HD and DTS-HD. Support for HD audio makes decoding high­resolution audio effortless – the uncompressed sound is always pure and crystal clear, delivering the total home enter­tainment experience that audio aficionados demand. In addition, the BD-D7500 features the new Ultra Fast Play technol­ogy which slashes boot-up time by 80 percent to just three seconds. To top things off, the BD-D7500 won the CES Best
of Innovations Award at this year’s Consumer Electronics Show.

So there you have it: 3D, 3D conversion, Wi-Fi, easy network connection, the Internet, Apps, movies, HD audio, shared
multi-media content, ultra-fast boot-up, and the Best of Innovations award. That’s the BD-D7500.
