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!

REPAIR / SERVICING TV SAMSUNG UE22F5410

Technical description and composition of the SAMSUNG UE22F5410 TV, panel type and applicable modules. The composition of the modules.

Panel: M215HW03
Power Supply (PSU): Adapter

General repair guidelines for TV LCD LED
If the SAMSUNG UE22F5410 does not turn on, no control lights on the front panel are lit or blinking, therefore, there is a very high probability of a malfunction of the Adapter power module. In some cases, only the processor power regulator may be faulty. In the absence of swollen filter capacitors of the secondary rectifiers, the diagnostics of the power supply should be started by checking the fuse and, if it is broken, it is first necessary to check all the power semiconductor elements of the primary circuit - diodes and transistors for the possibility of an avalanche or thermal breakdown.
For complex repairs of adapter power supplies, it is sometimes advisable to replace it with a new one.
If, when you turn on the TV, the image appears and immediately disappears, or is absent initially when you turn on, but the sound is there and other functions work, there is a high probability of a malfunction of the Led driver (power converter for the backlight LEDs of the M215HW03 panel).
Often in the absence of backlighting, disassembling the panel is required. It is necessary to check the serviceability of the transitions of the LEDs, as well as the reliability of the contact connections in the rulers and connectors.
To detect a break in the LED lines without disassembling the panel, a current source is required. It is impossible to open transitions connected in series with a simple multimeter; voltage of several tens of volts is necessary.
Repair or diagnostics of the BN41-01957C motherboard should begin by checking the stabilizers and power converters needed to power the chips and matrix. If necessary, update the software (software).
If there is no reception of television channels, but the TV is working properly from external devices, first of all it is necessary to check the voltage of the tuner DNTS403EL105A, exchange data with the processor and update the software.
Attention to the owners! Attempts at self-repair of the SAMSUNG UE22F5410 TV are not recommended by the manufacturer and can lead to serious negative consequences!
