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.

 ERROR CODES OPERATIONAL CHECK
The TV must be in “Shut Down” and not have been switched OFF, to perform the Error Code Operational Check. When the TV is switched OFF, the code automatically resets to “12” No Error.
  • Pressing the front panel “INPUT” and “MENU” buttons at the same time, and holding for 5 seconds, activates the Error Code Mode.
  • The “POWER LED” flashes denoting a two digit Error Code, or indicating no problem has occurred since the last Initialization.
Note: The front panel buttons must be used, NOT those on the Remote Control.
The number of flashes indicates the value of the MSD (tens digit) of the Error Code.
The flashing then pauses for approximately 1/2 second.
The LED then flashes indicating the value of the LSD (ones digit) of the Error Code.

The Error Code is repeated a total of 5 times.
EXAMPLE - When the error code is 35, the LED flashes.
RESET & INITIALIZATION
  • Many customer generated symptoms, intermittent symptoms or no symptom found can be resolved by using the various Reset and Initialization options. Before visiting the customer’s home ask the customer 1st to try the System Reset button on the control panel and if this does not resolve the issue, then they can perform an A/V Reset by pressing the Guide+ Format buttons on the front panel at the same time. Then, if necessary, perform a user level Initialization by pressing MENU-123-ENTER with the remote. The customer should be made aware when settings and/or options will be reset. For more information, see the chart below.
