When replacing a T-Con board, please be
aware of the fragile nature of the gold pads
on the ribbon cabling coming from the
panel. In the image below, you can see
clearly that the pads have been pushed
away from the Mylar ribbon. If the pads
are damaged as shown below, the entire
panel needs to be replaced. Worse, until
the panel is replaced, the TV is unusable.
It is a good practice to take a quick visual
of the pads before re-inserting the cable
into the new T-Con board. Also, take your
time and make sure you have good lighting
so you can align the slot of the connector
properly while inserting the cabling. The
ribbon cable should be inserted straight
into the connector. Avoid applying downward pressure or attempting to insert the
cable at an angle into the connector.
This is true for all LVDS ribbon cables.
Similar damage can create symptoms
from an intermittent image to complete
picture loss. In some cases, it could
cause the TV to appear DEAD.

LVDS Handling Techniques
Adam Vogel
Product Support
When working on today’s flat panel TV’s, it’s easy to point to such assemblies as the main board, SMPS, or even the
panel as the primary causes of defects. Generally I would agree, but with the growing delicacy of the LVDS cables, we
need to begin showing them a bit more attention. Below, I’ll give you a few examples of how paying closer attention to
the LVDS cable can prevent needless second calls, thereby saving you money!
CASE 1 – Traditional LCD
Notice the LVDS cable pictured left has two distinct ends. One
end, which connects to the main board, is very delicate and can
easily be damaged. The other end, which connects to the TCon
board, has a bit more rigidity but it too can be easily damaged.
Problem – Due to the length and delicacy of the LVDS cable, it can sometimes be difficult to insert the cable after a
main board assembly has been replaced.
Tip – Remove both ends of the LVDS cable from their respective boards, and then gently insert the delicate end first
(main board side). Once the delicate end is inserted and the tab secured, insert the second end into the TCon board.
CASE 2 – UN55C9000
The LVDS cable pictured left is a directional cable, which means
it will only function one way. To prevent the cables from being
inserted incorrectly, we have clearly labeled each end.
Problem – The UN55C9000, because of its unique design, offers some equally unique challenges when it comes to service. As you can see in the picture to the left, the LVDS cable is rather short, which limits its flexibility and makes inserting it into the FRC/TCon board and the docking board one of those challenges.
Tip – Although it is possible to get the LVDS cable inserted without removing either of the boards, it is much easier to
insert it before you screw the docking board into its mounting position.
Following these simple steps when reassembling a set can prevent additional damage to the LVDS cables, prevent additional visits to the customer’s home, and essentially create the perfect service scenario.

Inside Intelli-Studio

Product Support
Samsung cameras and camcorders have been sold since 2009 with proprietary built-in software called Intelli-Studio (IStudio). This software, which can run automatically when you connect your camera or camcorder to a Windows PC using a USB cable, has made it easy for customers to download and edit their pictures and videos. Unfortunately, IntelliStudio software has also caused many troubleshooting and service issues. This article discusses the basics of I-Studio
to help you prevent future No Defect Issues.
First, it is important to note that this software is only compatible with Windows PCs and is not compatible with Macs. In
most case, users can still connect their device to a Mac and drag and drop the files to their hard drive, but if they want to
edit any files, they will need to use 3rd party software.
Using Intelli-Studio on a Windows PC
Before you connect a camera or camcorder to a Windows PC, make sure that Intelli-Studio is enabled on your camera or
camcorder. To enable the software, select Menu-> Settings -> PC Software -> ON. If the software is not enabled, it will
not start automatically.
After you connect the camera or camcorder to a compatible Windows based PC, you must make sure that the device is
on. If the camera or camcorder is off, the software will not run. Some cameras or camcorders will prompt you to select
Computer or Printer after you connect it to a computer with the USB cable. If this message appears, you must select
Computer to continue.
After the connection is established, I-Studio will Auto run and ask if you want to transfer files from the device to the PC.
If you select Yes, you will see the transfer screen below. You must wait until the transfer process is complete.

The most confusing part about I-Studio is the double screen format. The Top window (labeled 1 below) is the computer’s hard drive and the bottom window (labeled 2 below) is the Camera’s built in and external memory.
The most common complaint that we are receiving is that customers see nothing in window 2 and are unable to transfer
pictures or video. See the illustration below.
This can occur if the camera is:

Not plugged in properly

Not powered on or

Has PC software disabled.
To troubleshoot, ask the customer to 1.) Check the USB connections from the PC and the camera or camcorder, 2.)
Make sure the camera or camcorder is on, and 3.) Make sure they have enabled PC Software. To enable PC Software,
the customer needs to select Menu -> Settings -> PC Software -> ON.

Some cameras have Internal and External Memory. If the customer complaint is that they do not have any pictures, it is
possible that they are looking at the wrong drive in the lower left section. In this case, have the customer check all the
drives listed under Connected Device before troubleshooting further.
Lastly, if the customer wants to edit pictures or videos on their PC, they must either install the I-Studio software onto their
PC or connect their device each time they want to see and edit images. If the customer does not install I-Studio on their
PC, they will not be able to use it when the camera is disconnected.
To install the software, follow these steps:
1. Connect your device to the PC and turn it on, and then wait as Intelli-Studio auto-runs and loads.
2. In the upper left corner of the Intelli-Studio screen, click Tools → Install Intelli-studio on PC.
You can also install Intelli-Studio by following these steps:
1. Connect your device to the PC and turn it on.
2. Double click My Computer.
3. Right click the “IntelliStudio Drive” and click Explore.
4. Double click the “Setup F” icon
5. Follow the on screen prompts to install I-Studio to your desired location.
a. Click to accept the terms of I-Studio.
b. Select the location you wish to install to.
c.
Click on Install and wait for the installation to finish.

Plasma TV Repair Made Simple, Part 3

Trainer—RTSC
In the first two articles, we emphasized the importance of taking the “Vital Signs” (Vs, Vsc, Va, Ve) before or during every
repair. You can take these voltage readings in less than 5 minutes and in most cases, the readings will lead you directly
to the failure. Even if a unit is shutting down after only 3 seconds, there is still plenty of time to take the readings.
Now let’s look at other key repair observations.

Figure 2
Figure 1
The supply first delivers the important 5V Standby Voltage (normally 5.3V on pin 2, STBY, in the Figure 1 examples) to
the Main Board Assembly which in turn provides the PS_ ON, “Power Supply On command” to the supply. Stand-by voltage is also provided to the Logic Board. The SMPS may also supply other un-switched voltages, and, depending on the
model, 33V to the tuner so the tuner remains active during stand-by and 12V to the Logic Board (older models).
Switched voltages also include Vs (approximately 210V), Va (approximately 55V), and, in Figure 1 – the 9 and 12 pin
configurations - connectors to the Main Board: 5.3V, 15V, 18V, and 6.3V.
Testing and Turning On the Supply
You can check the Standby Voltage by first observing the Red LED Power indicator on the front of the panel. Red LED
illumination normally indicates operating 5V standby to the Main and Logic Boards.
The Main Board then turns on the SMPS by providing a “Low” (3.3V to 0 V) voltage signal, PS-ON, to the SMPS and
additionally to the Logic Board connectors. The Logic Board then provides VS_ ON (pin 6 CN802 in Fig 2), a “High” activation signal (0V to 3.3V ) to the SMPS to turn on Vs which starts the operation of the Panel Drive Boards.
You can test the Power Supply turn on operation without the Main Board operation by simply removing the Supply connector off of the Main Board side and shorting out (with a bare wire) PS-ON to circuit ground. (Pin 1 to pin 5 of Figure 1,
in both connector examples.)

Example 1
The TV’s Red LED Standby Indicator is off and the TV will not turn on.
Troubleshooting:
1. Measuring 5V Standby (pin 2, Figure 1) confirms the standby voltage is missing (0V).
2. Removing CN801 to the Main Board and CN802 to the Logic Board (since Main and Logic get 5V standby) confirms
neither assembly is loading down the missing 5V supply.
Repair:
Replace the defective Power Supply.
Example 2
The TV’s Red LED Standby Indicator is on, but the TV won’t power on.
Troubleshooting:
1. Measuring 5V Standby (pin 2, in Figure 1) to the Main Board confirms the LED Indicator is accurate and that the
Standby voltage is good.
2. Measuring PS-ON shows that PS-ON stays at 3.3V and does not go to 0V “low”.
3. Removing the connector at the Main Board and inserting a short from PS-ON to the circuit ground (pin 1 to pin 5 of
the Figure 1 connector examples) confirms proper Power Supply On.
Repair:
Replace the defective Main Board.
Example 3
The TV’s Red LED Standby Indicator is on, but the TV won’t power on. The panel shuts off after 3 seconds.
Troubleshooting:
1. Measuring Power Supply Va (Address Voltage) indicates that the voltage is OK (approximately 55V), however, Vs
remains at 0 Volts during the 3 seconds of the activation attempt.
2. Removing AC power and testing Vs indicates a short to ground.
3. Removing SMPS Vs supply connectors, one at a time, to the X Board and Y Board indicates Vs is shorted at the X
Board.
4. Connecting the AC and powering on the TV while keeping the Vs feed connector to the X Board disconnected restored the Vs voltage reading on the Power Supply during the 3 seconds of activation.
Repair:
Replace defective X Drive Board.
