REPAIRING AND NOT THROWING AWAY

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 Flashing
LED flashing specification at the time of the error
Display method
Make the OPC LED flash using the [MENU] key on the remote control since the display for service persons is identified by the number of flashings (once to 5 times). Even if the [MENU] key is pressed again, it does not return to the display for customers (only the power LED flashes).
After recovering from an error, if the same error cannot be generated again, refer to MONITOR ERR CAUSE on the adjustment process screen. shing method
Synchronize the phases of the power LED and OPC LED.
If the LEDs have different number of flashings, adjust the flashing cycle to that where the LED flashes more times
Cleaning the LCD
Ensure you unplug the power cord before cleaning the LCD. The cabinet as well as the operation panel is made of plastic. Avoid using benzene or thinner, as these can damage the finish on the cabinet.
Do not use volatile agents such as insecticides on the LCD. Do not attach rubber or plastic items on the LCD for long periods of time.
The effects of some of the agents in the plastic may cause damage to the quality or finish of the LCD.
Wipe off dirt gently with a soft flannel cloth.
When the dirt is hard to remove, soak a cloth in a neutral detergent diluted with water, wring the cloth well and then wipe the LCD.
Strong cleaning detergents may discolour, warp or damage the coating on the LCD.
Ensure you test on a small, inconspicuous area on the LCD before using.
