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.

SONY KV- 32HQ100B - KV-36HQ100B - TRINITRON - SELF DIAGNOSTICS - ERROR CODES - LED BLINKING CODES


ERROR CODES & SELF DIAGNOSTIC FUNCTION
 Error diagnostics are used to diagnose if parts of the chassis are faulty. Some errors can be safety critical. In this case the TV set is put into standby.


An error is communicated by:
  • Flashing the LED red at the front of the TV
  • Via the error monitor service menu
  • Via the Customer Service Menu (CSM)
  • Via an external error reader connected to the service connector.
LED ERRORS
  • The most important errors are signaled via this method.
  • This is also the only way that safety critical errors can be communicated since the TV will be in standby.
  • The LED sequence below is an example of Error Code 3. An error is determined by the number of short red flashes of the LED in between a longer solid green LED indication.
LED ERROR CODES [To Magnify the images, Click on it]
  • LED code 1 has the highest priority.
  • Errors found corresponding to LED error codes 2-4 will put the TV into standby under all conditions.
  • However, an error corresponding to LED error code 5 (Unstable AKB) will only put the TV into standby in service mode – the LED will flash in production mode without the TV going into standby.
ERROR MONITOR MENU
The error monitor is displayed by:
  • Entering TT command TT99, or
  • Executing the following key sequence when the TV set is in standby:
The error monitor displays the following information:
  • The last 5 errors that are stored in flash
  • The current error
  • The operating time of the TV set. 
                        Error detection can also be enabled or disabled from this menu.
The following error messages are displayed in the error monitor. The error code is displayed in the external error reader.

ERROR READER DISPLAY

  • If no menu can be shown, the Error Reader can display the current error. The error reader display is connected to the service connector to read actual error codes. The part number for the error reader display is S-188-900-10. Once an error has been detected it will then be displayed on the two digit error reader. The errors displayed refer to the above table.

Due to the limited count of digits the Error Reader displays the message sequentially. The following example shows the definition of this sequence:
  • Start new error sequence [ .]
  • Display of 1st error part 1 [ 4 .]
  • Display of 1st error part 2 [ 0 1 .] Error Code = 401h
  • Display of 2nd error part 1 [ 6 .]
  • Display of 2nd error part 2 [ 0 1 .] Error Code = 601h
