REPAIRING AND NOT THROWING AWAY

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.

PANASONIC - TY-TP42P10S _ TY-TP50P10S _ ADJUSTMENTS _ SETTING RANGE OF OPTICAL AXIS _ ADJUST & CONFIRM THE LIGHT LEVEL






OPTICAL AXIS RANGE SETTING

Purpose for adjustment: Make L and R sensors recognize the starting point (first) and ending point (last). Adjust lfirst, rfirst, llast and rlast.





  • Touch PDP display area corner top right. The blue wave shape of the left sensor falls down. Adjust lfirst and match the yellow line to the dent of the wave shape.






  • Touch PDP display area corner bottom left. The blue wave shape of the left sensor falls down. Adjust llast and match the yellow line to the dent of the wave shape. (*If two dents appear, pick the one close to the center of the wave)



  • Touch PDP display area corner bottom right. The blue wave shape of the right sensor falls down. Adjust rfirst and match the yellow line to the dent of the wave shape.  (*If two dents appear, pick the one close to the center of the wave).


  • Touch PDP display area corner top right. The blue wave shape of the right sensor falls down. Adjust rlast and match the yellow line to the dent of the wave shape.


  • Press "Write to ROM" to write the adjustment result.

ADJUST THE LIGHT LEVEL

Purpose for adjustment: Confirm that the enough light level to operate Touch Panel properly is secured.
  • Press "Auto set" at left and right.
  • Press "Initialize" after press "Write to ROM" to save the data.



  • Confirm that the weakest point of left and right wave shape (light level) is level 2.5 or more.



  • If dust exists on the sensor unit or reflection plate, necessary light level may not be secured. Clean the reflection plate and the floodlight lens of the sensor part.
  • If the weakest point is below 2.5, set "LED power" current to "High" by opening "Common" tab in Parameter.



  • If the weakest point is still below 2.5 although setting "LED power" current to "High", open "Sensitivity" tab in "Parameter" to adjust the sensor sensitivity.
  • If you set the wave shape to too high level more than necessary, thin things cannot be recognized. When confirming the thinnest value detection, NG will appear.
