REPAIRING AND NOT THROWING AWAY

Richtige Fernseher haben Röhren!

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.

LED BLINKING ERROR CODE SERVICE MODE AND ADJUSTMENTS 

SELF DIAGNOSTICS
When safety shutdown occurs, LED display reports the cause by using the Lighting patterns as indicated below. Since there are various failure items in WAX model. Light blinking is used so that shutdown causes can be judged from the number of blinking times. The items corresponding to the number of blinking times are indicated as follows

How to enter Service Mode
Service adjustments to this model can be performed using the supplied Remote Commander RM-GA008
1. Turn on the power to the TV set and enter into the stand-by mode.
2. Press the following sequence of buttons on the Remote Commander.
(STBY) - (ON SCREEN DISPLAY) -  (CH 5) - (VOLUME +)  - (POWER)
3. The menu will then appear on the screen.
4. Move to the relevant command using the up or down arrow buttons on the remote commander.
5. Press the right arrow button to enter into the required menu item.
6. Press the ‘Menu’ button on the remote commander to quit the service mode when all adjustments have been completed.
Note:
– After carrying out the service adjustments, to prevent the customer accessing the ‘Service Menu’ switch the TV set OFF and then ON.
Aging
1. Aging setting
i. Set no signal and monitor as aging mode.
2. Aging condition
i. Aging condition before white balance adjustment is as follows;
Supply Voltage : Rating
Time : 20 minutes or over
(AGING_TIMER registor setting)
Ambient temp : 22 - 28°C
Brightness : Brightness is set by aging mode
Input : Set no signal except digital and analog RF (video/component/PC)
3. LED lighting pattern during aging
In case that AGING_TIMER > 0
Green (0.5s) >
off (0.5s) > Green (0.5s) >  off (0.5s)
Notes: Green (Power LED is ON/OFF)
In case that AGING_TIMER = 0
Green (3.0s) >
off (3.0s) > Green (3.0s) > off (3.0s)
Notes: Green (Power LED is ON/OFF)
Note:
If set has been put on surface down, brightness surface irregularity is caused by static electricity. If so be, turn set over or keep it upright more than 30 seconds. As surface irregularity is vanished away, then check the set.
