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.

  • Press & Hold the {P +} button on the TV set, and switch the TV On, by its Mains Power Switch.
  • The 'L+' button on the TV set allows to discover other potentially defective interfaces.  If there is no other defective interfaces, the software tries to start the TV set.
  • The error messages for the DSP, SAT & PIP modules are only indicated if these modules are actually fitted and the least one IIC bus address on the defective module has been identified.  These error messages refer only interference only in the IIC bus, that is, to those moldules or integrated circuits which do not return an Acknowledge bit via IIC bus, for example, to indicate that there is no operating voltage present on the module, that there is a break in the circuit path, or that the IIC interface is defective.

SAT Module Programming 
  • Press and Hold the "i" button on the remote control and switch the TV On, with the Main Switch.  Consequently, on replacement of the EEPROM on the SAT module for example, the stored station table is read out from EPROM IC87030.
CANCELLING THE PARENTAL LOCK
  • To cancel personal code number, press the buttons { < > Dn Up} in sequence.
EPROM Version Number
  • Press button "i" to call up the "DIALOGCENTER" menu.  The version number is shown by pressing "AUX" button.  The index '07' of the part number (19798-311-07) indicates the EPROM version.
SWITCHING ON WITH TEST PATTERN OR TV MODE
  • Call up the Menu "Switch On with test pattern or TV" with "i" button via"DIALOGCENTER" => 'SERVICE'.  On selection of 'Test Pattern' an integrated test pattern will appear on the screen when switching the TV on again.  The 'TXT' button is used to switch the TV back to Program Mode (if no other button is pressed during a period of ca.20s the test pattern reappears).
