REPAIRING AND NOT THROWING AWAY

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.

Setting the Initial data
This adjustment is controlled by the CPU (IC8000) through the IIC Bus Data Line in the chassis, and those adjustment data are memorized the memory IC (IC7 00). Therefore, Main board or the memory IC (IC7 00)
is replaced, these data will be disappeared. Readjust should be made. Initial data is provided in the CPU ROM, when the memory IC (IC7 00) is replaced with new one. CPU ROM data is loaded into the memory.
Initial data is provided to operating the monitor basically. For operating the monitor quality performance, further adjustment is required following chassis electrical adjustment.
Receive good quality signal.
2. Enter the Service Mode.
3. Confirm data value to be the same as the Service Adjustment Data Table. If it is different, change to correct data
4. Exit the Service Mode.
White and Black Balance Adjustment

3. Set R,G,B value to “FF” by pressing NUMERIC buttons.
To adjust Red : Press 1 (data value up) and 4 (data value down).
To adjust Green : Press 2 (data value up) and 5 (data value down).
To adjust Blue : Press 3 (data value up) and 6 (data value down)
4. Decide one item in three items to a fixed value (For example, let R be fixed value), select item of other 2 colors (Example, G or B), and adjust to produce a normal black and white picture in highlight areas.
(Note: At this time, Adjust the other 2 colors data less than fixed data.)
5. Exit the Service Mode.
