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.

Self-Diagnosis Function
This device includes a self-diagnosis function.
In case of abnormalities, the POWER/STANDBY indicator automatically blinks. It is possible to predict the abnormality location by the number of blinks. The Instruction Manual describes blinking of the POWER/STANDBY indicator.
If the symptom is not reproduced sometimes in case of a malfunction, there is recording of whether a malfunction was generated or not. Operate the remote command to confirm the matter on the screen and to predict the location of the abnormality.
Diagnosis Items and Prediction of Malfunction Location
When a malfunction occurs the POWER/STANDBY indicator only blinks for one of the following diagnosis items. In case of two or more malfunctions, the item which first occurred blinks. If the malfunctions occurred simultaneously, the item with the lower blink count blinks first.  The screen display displays the results regarding all the diagnosis items listed below.  The display "0" means that no malfunctions occurred.
To Release of POWER/STANDBY indicator blinking
The POWER/STANDBY indicator blinking display is released by removing the plug from the power or leaving for 2 minutes.
Self-diagnosis screen displays
In cases of malfunctions where it is not possible to determine the symptom such as when the power goes off occasionally or when the screen disappears occasionally, there is a screen display on whether the malfunction occurred or not in the past (and whether the detection circuit operated or not) in order to allow confirmation.
Screen Display Method
Quickly press the remote command button in the following order from the standby state.
DISPLAY > CHANNEL (5) > VOLUME (--) > POWER
# Numeral "1" means a fault was detected one time.
# Numeral "0" means that no fault was detected.
The results display is not automatically cleared. In case of repairs and after repairs, check the self-diagnosis screen and be sure to return the results display to "0".
If the results display is not returned to "0" it will not be possible to judge a new malfunction after completing repairs.
Method of Ending the Self-Diagnosis Screen
When ending the self-diagnosis screen completely, turn the power switch OFF on the remote commander or the main unit.
Self-Diagnosis function operation
2) Temp >>  When the temperature sensor (for Ambient) on the S1 board detects high temperature or the temperature sensor (for Lamp) on the S2 board detects high temperature or the temperature sensor (for Panel) on the C board detects high temperature, the DE-micro (IC5) turns off the lamp.
3) Lamp cover >> The rib at the back of the lamp cover closes the SW on the T1 board. The lamp closes the SW on the T2 board.  It is monitored by DE-micro (pin63 of IC5) and turned off the lamp when it is opened.
4) Fan >> Fan rotation is detected by ‘‘FAN-PROT” and the DE-micro (pin92 of IC5) turns off the lamp when it is ‘‘high”.
5) Lamp Driver >> When the ‘‘LAMP-PROT” (pin83 of IC5) is high, the lamp is not turned on.  If the ‘‘LAMP-HV-DET” (pin94 of IC5) is low at the same time, it classified as no high voltage of the lamp driver.
6) Low B error >> When no ‘‘D5V (SW_5V)” is detected, pin 129 of TV-micro (IC7002) is low and it turns off the main power. (for example, blowout of thermal fuse).
7) Audio >> When DC voltage is detected at the speaker output, ‘‘SP-PROT” (pin102 of IC5) is low and it turns off the main power.
8) D-OVP >> Be not in use.
9) Panel error >> When there is no track from the temperature sensor on the S1, S2 and C board or IIC line connector (CN2303: ASU board, CN7956: DSU board, CN6901: C board) is not seated securely. It is monitored by DE-micro.
10) ATSC-OVP >> Be not in use.
(LAMP) - Lamp >> When the ‘‘LAMP-PROT” (pin83 of IC5) is high, the lamp is not turned on. If the ‘‘LAMP-HV-DET” (pin94 of IC5) is high at the same time, it classified as no lamp or a dead lamp.
