REPAIRING AND NOT THROWING AWAY

Richtige Fernseher haben Röhren!

Richtige Fernseher haben Röhren!

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.

SYSTEM INFORMATION

SW UPGRADE
Upgrade TV: update item
Bin Name: Software bin name.

Upgrading the software
MSD3463 has two kinds of chips: MSD3463GSA and MSD3463GU. Please make sure that you get
the correct upgrading file for a certain chipset (refer to the chart below).   Introducing 4 upgrading methods one by one: User menu Upgrading, Power on Upgrading, Factory Setting Upgrading, ISP Upgrading. The former three are most commonly-used.

Preparation
This step only applies to power integrated board.
Prepare mini power board(CN.UPGRADE01) for upgrading.

Connect the mini board with main board as below:

Make sure connect the 12V to 12V and GND to GND, or it will cause hardware damage.
 The main board should be connected to mains to work if we do not use the CN.UPGRADE01 board. The power module of main board have more than thousands of volts at working. It is easily leads personal injury or damage to equipment if  mistakenly touch the main board or some objects fallen into the main board during the upgrading procedure. So  use the CN.UPGRADE01 board to reduce the risk of upgrading.

Please keep the electricity ON in the upgrade process.
Operation Procedure
Copy the Upgrading File (SW) to a USB disk and then insert it to the USB port. Search for the SETUP and select Software Update by Left or Right  remote control key on User OSD Menu. The pictures below are the upgrading procedure for your reference:

Upgrade Prompt
When upgrading, the TV set will light panel according to the panel parameter, and display the progress bar. If the panel parameter of board matches the panel, you will see the following image:

100% indicates the upgrade finished, and TV will auto reboot after user menu upgrading finished.
 Upgrade Flashing Status
You can judge the upgrade progress by flashing of the remote control LED light:
Upgrading:
Red 1000ms Green 1000ms alternates, the TV set will turn to Upgrade succeed or Upgrade Failed status after the upgrading process.
Main program upgrade succeed:
Red 250ms Green 250ms alternates, flashing before power off.
Main program upgrade Failed:
Red 1750ms Green 250ms alternates, flashing before power off.
Notes: In the upgrade process, as timer software is used to control flashing, situations such as LED light stuck when creating partition of flash, is normal phenomenon.
Power On Upgrading
Copy the SW to a USB disk, link it to the USB port, Re-power on, if the LED blinks continually, it means the upgrading is on process, while the LED light off means the upgrading has been completed.

Factory Setting Upgrading
Press <MENU>+1147 to enter the factory setting, search for the “Upgrade” item by the remote control, just like the picture below, then you can follow the steps in the screen.
