REPAIRING AND NOT THROWING AWAY

In Brief: On this site you will find pictures and technical information about Service Modes, Circuit Diagrams, Firmware Update procedure, Disassemble procedure, Universal remote control set-up codes, Troubleshooting and more....

If you go into the profession, you will obtain or have access to a variety of tech tips databases HERE IT IS Master Electronics Repair !.

These are an excellent investment where the saying: 'time-is-money' rules. However, to learn, you need to develop a general troubleshooting approach - a logical, methodical, method of narrowing down the problem. A tech tip database might suggest: 'Replace C536' for a particular symptom. This is good advice for a specific problem on one model. However, what you really want to understand is why C536 was the cause and how to pinpoint the culprit in general even if you don't have a service manual or schematic and your tech tip database doesn't have an entry for your sick TV or VCR.

While schematics are nice, you won't always have them or be able to justify the purchase for a one-of repair. Therefore, in many cases, some reverse engineering will be necessary. The time will be well spent since even if you don't see another instance of the same model in your entire lifetime, you will have learned something in the process that can be applied to other equipment problems.
As always, when you get stuck, checking out a tech-tips database may quickly identify your problem and solution.In that case, you can greatly simplify your troubleshooting or at least confirm a diagnosis before ordering parts.

Happy repairing!
Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.

FLASH PROGRAMMING
“The Flash Programming Software Kit 9965 100 17380.zip”includes the following application and driver software for firmware upgrading of IPOD, HDMI CEC and Power Box software in HTS8140:
  • Flash Programmer (Flash MCU Programming Software)
  • PL-2303 USB-to-Serial Driver.
Here it is generally describes how to install the driver, how to prepare the Flash Programmer Application, and how to upgrade the software of the target module. The service manual of the set will include the information on software upgrading and other software features for service in more details.
Installing USB-to-Serial Driver in service PC
  • Extract “PL-2303 Driver Installer” from “Flash Programming Software Kit.zip” into a destination folder in service PC. PL-2303 Driver should appear as an icon in destination folder as shown.
  • Double-click the icon to run the InstallShield Wizard and follow the on-screen instructions then to install the driver.
  • When the driver installation is completed, go to Control Panel -> System -> Hardware tab -> Device Manager-> Ports (COM & LPT). If the interface programming interfaces board is connected to service PC via USB cable, it should appear as “Prolific USB-to-Serial Comm Port (COMx)” in Device Manager.
  • Take note of the COM Port number to use it for setting the Flash Programmer Communication configuration, which will be described.
Note: the USB-to-Serial Comm Port will not show up in Device Manager if the programming interface board is not connected to service PC via USB cable.
Preparing Flash Programmer Software
  • Open zip file “Flash Programmer.zip” from “Flash Programming Software Kit.zip” and extract all the files as shown in figure 4. A folder “Flash Programmer” and 8 setup files should appear in the destination folder as shown.
Preparing the Flash Programmer
Configuring the work environment features
To use the flash programmer application to download the software upgrade to the target board, the following work environment features must be configured:
  • The setup file to be used
  • The target device name
  • The COM port and data transfer rate
Follow the procedure below to configure the work environment features:
  • Run the flash programmer”FlashProg.exe”. The Flash Programmer main window will appear. Go to Setup -> Setup File as shown.
  • Setup dialog box will then pop up. Go to “Setup File” tab, “Browse” the folder that contains the setup files as shown in figure.
  • locate setup file
  • For example, if the target board is MPEG Board for downloading the IPOD software, then the setup file should be HTS8140_IPOD_V1.0.ini.
  • Go to Device tab as shown in figure 9. Choose the MCU series and type for the target module as described in to table 3 (in next coming section). Click “Apply” to confirm selection. The MCU type will appear in “Chosen Device” box.
  • Series and Device
  • For example, if the target board is MPEG Board for downloading the IPOD software, then the target device is TMP91FW60 in series 900/L1. After clicking “Apply” button, the chosen device TMP91FW60 should appear in the Chosen Device box.
  • Go to communication tab as shown in figure.  Choose the USB-to-Serial COM Port number from the COM port drop down list.
Choose COM Port and Data Rate
For example if the target module is MPEG board for downloading IPOD software, then the data rate should be 19200 bps
Note: The COM port number for USB-to-Serial COM Port will not appear in the drop down list in the Communication tab of the Setup dialog box if the programming interface board is not connected to service PC via USB cable.
Select the Data Rate as described in table.
Procedure to upgrade the firmware via Programming Interface Board
