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.

SONY KDL32BX355 _ NUEVO_ TROUBLESHOOTING_ STANDBY LED BLINKING CODES

SONY KDL32BX355 _ NUEVO_ TROUBLESHOOTING_ STANDBY LED BLINKING CODES


UPDATING SOFTWARE
The Self Diagnosis function is designed to provide information regarding the problem with the TV, however, there are several issues that may be resolved by updating the TV software to the latest version. Always check for any issues that are software related. Most symptoms that are correctable by software updates involve communications issues with other devices or minor glitches in the operation of a specific function. Below is a list of some of the symptoms that may be corrected with a software update:
Fluctuations in picture brightness
Intermittent picture freezing or noise
Problems with certain inputs (especially HDMI)
Intermittent or distorted audio
Erratic remote control operation
TV turns on and off by itself
Loss of color
Internet connectivity
Certain features not working correctly (photo or video file viewing).

SELF DIAGNOSIS FUNCTION
The CPU on the Main Board monitors critical voltages and circuit operations. If an error is detected the Self Diagnosis function in the TV will force the TV to shut down by the CPU. The monitored circuit in which the fault occurred will automatically cause the CPU to blink the Standby LED in groups of repeating sequences. The number of times the Standby LED blinks indicates the possible cause of the problem.
Not all of the available protect codes are used in every model.
For example, models that don’t have the local dimming feature do not use the 4X blink error as this circuit is found in models that are back-lit with fluorescent lamps. The information in this section provides guidance in locating the possible component causing the shutdown.

VIEWING SELF CHECK DIAGNOSIS HISTORY
When an error is detected, the Self Check screen records the error that occurred. This is helpful in confirming past occurrences of an error, and for determining if an error is intermittent when the customer is not sure what is causing the television to shut down. If the screen displays a “0”, no error has occurred.
You must got into Service Mode to access the Self Check menu.
TV must be in Standby mode. (Power On).   Press the following buttons on the Remote Commander within a second of each other:
  • {<-- / --> / MUTING / [ + ] / MUTING / VOLUME [+] }  Remote control number to this set is [RM-YD081].
  • To access the Self diagnosis history page, press until Self diagnosis history is highlighted, and then press
    Review the information to determine the most likely source of the error.
    To exit the Self Check, press MENU .
STANDBY LED BLINKING CODES.

2X Blink - Main Power Error
A loss of REG12V from the power supply triggers this protect event. The usual cause is a failure of the main switching supply. In some instances, excessive loading on the secondary supply lines can cause the switching regulator to stop, or fail again, if a replacement board is installed.
3X Blink- DC Regulator/Audio Error
The REG 5V and D3.3V source originating on the Main Board is monitored for low-voltage conditions by the CPU. A failure causing a 3X shutdown requires replacing the Main Board.
NOT USED IN THIS MODEL SERIES
4X Blink – Balancer Error
The 4X error code is only used on models incorporating local dimming LED backlighting. If a failure occurs on the LD board or one of the LED’s fails in the panel the TV will shut down and display this diagnostic code. Models using conventional non-local dimming LED backlighting do not utilize this error code.
5X Blink - TCON Error/Panel Error
The 5X blink protection mode indicates a communications error with the timing control circuits (TCON Board) has occurred. If the TCON Board is available for replacement, replace it, if not, replace the LCD Panel Assembly. In rare cases a loose or defective LVDS cable could also be the cause.
6X Blink - Backlight Converter System Failure
If the inverter circuits fails to generate high voltage or one or more of the backlight lamps fails to light, the television will shut down and display this diagnostics error. Observing for the presence of backlighting is crucial in determining which component is likely at fault.
If the backlights turn on before the 6X shutdown occurs, it is safe to assume that the inverter circuits are functioning and one of the lamps failed to ignite. Replacing the LCD Panel assembly is necessary. If the backlights never turn on before the 6X shutdown, the Inverter MT Board has failed. If this board is available for replacement, replace it, if not, replace the LCD Panel Assembly.
7X Blink - Temperature Failure
A digital thermometer IC located on the Main Board provides a temperature reading of the chassis and LCD panel. If the temperature exceeds a pre-determined point the TV will shut down. If this problem occurs immediately at turn-on, the temperature sensing IC has failed and replacing the main board is required. If this occurs after the TV has been running for a while, check for ventilation issues that could cause the TV to run hotter than normal.
