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.

Lamp error detection
Function description
This LCD colour television has a function (lamp error detection) to be turned OFF the TV set automatically for safety criteria when the lamp or lamp circuit is abnormal. If the lamp or lamp circuit is abnormal, or some other errors happen, and the lamp error detection is executed, the following occurs:
a. The TV set is turned OFF automatically 20 seconds after it is turned ON by the user.
(The power LED on the front side of TV turns from green to red)
b. If the situation “a.” happens 5 times sequentially, it becomes impossible to turn on the power.
(The power LED turns from green to red and keeps blinking in red).
Countermeasures
a. Checking with [L Error Check Off]. Repair the problem that produces the LAMP ERROR. The TV remains with power LED blinking until K mode is forced by local keyboard, in order to disable the LAMP ERROR detection. To disable the LAMP ERROR feature is necessary enter in K mode by pressing “VOL DOWN” and “INPUT” keys at same time when the AC cord is plugged in.
b. Resetting the LAMP ERROR counter. After the lamp and lamp circuit are found out of trouble, the LAMP ERROR counter should be reset. If a LAMP ERROR is detected five consecutive times, the power cannot be turned on.
Method 1: Using the cursor (UP/DOWN) key, move to the cursor to [L Error Reset] on Line 6 of ETC Menu Fig
4. With the cursor (LEFT/RIGHT) keys reset the value to “0”.
Method 2: In the case the TV is not blocked (less than 5 consecutive errors), switch on the Set. After 30 minutes working, the LAMP ERROR counter will be reset automatically.

replicate the user settings of one TV into another. These settings include (but not restricted to): picture and audio, tuning set-up, language and country selection, PIN, child locked programs… Factory adjustments are not copied as they are different for every TV.
The Smart loader makes possible the user data to be stored in a memory device connected to the USB terminal of the TV that is used as reference and later load those data into other TVs by using their respective USB terminal.
How it works.
In reference TV:
1. Insert a memory device in the USB slot.
2. Enter in service mode, select Factory Menu and SMART LOADER option.
3. Select “Save settings to USB” and press the RIGHT cursor in the remote control.
4. Wait until “OK” is displayed, the file has been successfully created in the root directory of the memory device.
In case of error, an explanation message is shown.
In TV to be cloned:
1. Insert a memory device with a file in it obtained following the above procedure.
2. Enter in service mode, select Factory Menu and SMART LOADER option.
3. Select “Load settings from USB” and press the RIGHT button in the remote control.
4. After some seconds, “OK, reboot TV set” is displayed. In case of error, an explanation message is shown.
