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.

SAMSUNG PS42D5SX - PLASMA TV - FAULTS - WIRING DIAGRAM - CONNECTOR VOLTAGES

PS42D5SX - SAMSUNG PLASMA TV - FAULTS - WIRING DIAGRAM - CONNECTOR VOLTAGES

Samsung PS42D5SX/XEC - PS42D5SX/XSG - PS42D5SX/XTL Plasma Display TV - Common Faults - Wiring Diagram _ Connector pin Voltages.

THE TV IS HOT

Since a PDP TV displays a picture on the screen by discharging plasma, operating for a long time may introduce heat onto the panel. The internal heat of the panel is sent to the vent on the upper part of the product, and users must take care not to touch the hot air from the vent. The heat from the PDP TV does not indicate a defect or problem.

NOISE FROM THE TV

A PDP TV may produce sound at a certain level when operating the fan to cool its internal temperature. In addition, since the high-speed switching circuit and the high current may produce noise depending on the screen brightness change, a PDP TV produces more noise than a conventional CRT TV.

AFTER IMAGE REMAINS ON SCREEN

Due to the nature of PDP TVs, partial after-images may appear if a still picture is displayed for a certain period of time after connecting a video game console or a computer. This is caused by brightness deterioration due to the storage effect of the panel, and to prevent this from happening, we recommend you reduce 'brightness' and 'contrast'.

RED OR BLACK SPOTS APPEARS ON THE SCREEN

A PDP TV uses a PDP panel consisting of 123million (SD Grade) ~ 315million (HD Grade) pixels. Although a PDP panel is a product that requires high technologies to integrate a few million pixels, a bright or dark pixel may exist on the panel, this does not affect the performance of the product.

BOUNDARY APPEARS ON THE SCREEN

Displaying a still picture on the screen may permanently damage the PDP panel.
A boundary may appear due to the difference in the transparency of the panel when watching the picture in the 4:3 aspect ratios for a long time and the picture in the left, right and center screens is a still image.
A boundary may appear when watching a still picture from a DVD player or a video game console on the screen for a long time.

UNUSUAL LINES APPEARS

Keep the antenna away from the power cord or connectors if possible.

The SMPS relay repeatedly turns on and off by the protection function due to a defect on a board connected to the SMPS.

> Disconnect all cables from the SMPS, operate the SMPS alone and check if the SMPS works properly and if each voltage output is correct.
> If the symptom continues even when SMPS is operated alone, replace the SMPS.
> If the symptom is not observed when operating the SMPS alone, find any defective ASSYs by connecting the cables one by one.

[When separating and connecting the cables such as CN809 of the Main SMPS, CN1, CN2, CN3, CN4 and CN5 of DC-DC SMPS, CN of the X Drive Board, and CN of the Y Drive Board, a spark may be generated by the electric charge of the high capacity capacitor. Therefore, wait some time after separating the power cord from the unit.]

The SMPS relay or the LEDs on the front panel do not work when connecting the power cord if the cables are improperly connected or the Video Board or SMPS is out of order. In this case, check the following

* Check the internal cable connection status inside the unit.
* Check the fuses of each part.
* Check the output voltage of SMPS.
* Replace the Video Board
