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.

PANASONIC - TY-TP42P10S _ TY-TP50P10S -TOUCH PANEL _ TO REWRITE DATA WHEN REPLACING MOTHER BOARD.




RE-WRITE DATA 

  • Adjusted data is saved respectively in EEPROM inside the Main Board.
  • Start "LtabMonA" with Touch Panel connected.
  • Press "Parameter" after start "LtabMonA".
Parameter display appears. (The data of the Main Board currently connected is shown.)
Press "Save File" button and save as "Name". (extension.prm)
The data write on the new Board.
  1. Press "Load file" and specify the data saved as above. (extension. prm)
  2. The data which was read is displayed.
  3. After that, press "Write to ROM" and the data is written.  (Unless you push the button, the data cannot be written.
  4. Press "OK" to close "Parameter" display.
  5. After writing the data, finish "LtabmonA" once.
  6. The written data is enabled by removing and inserting the USB cable.
  7. The basic operation for replacing the Main Board finishes here. Confirm the contents to be checked after adjustment.
  8. Some components come to the end of life and may not be recovered to the shipping condition.
  9. If the check contents cannot be satisfied, adjust the items. If it still cannot be recovered after adjusting all items, changing the Sensor Boards is necessary.

Purpose for adjustment : Adjusting so that L and R sensors can receive the reflected light properly from the reflecting plate.
  • Start "LtabMonA" with Touch Panel connected.
  • After starting "LtabmonA". the sensor wave pattern appears. Add check mark for "Continuous" and "2D image".
  • Display "Parameter" and select view "Camera Scope" tab.
  • Press "L Search". It will take time to search for the optical axis.
  • When the wave shape is swollen, press "Auto set". The wave shape is more swollen and then L optical axis adjustment is complete.
