Ohm’s Law a reminder that basic electronic circuits follow Ohm’s Law to some extent.               Ohm’s Law       V=I/R     Ohm’s Law fails when significant temperature changes occur or when certain “non-ohmic” materials are used POWER Power is simply the energy required to do something. If you are moving a large number of electrons and moving them through something that is resistant to that movement, power is used. Power is voltage times current. Power is also voltage squared divided by resistance. In electronics, we use the flow of electrons to drive a variety of processes. P = I x V Power = Watts/time P = V 2 /R Resistors A resistor is a component that resists the f...

Panasonic Plasma TVs have built-in fault diagnosing circuit.  If any fault occurs with any circuit board inside, the loaded firmware will detect it and will give you its indication in the form or standby light blinks. From the number of blinks at one time, experienced service technicians can detect the faulty section [circuit board], without opening the TV.  This will help technicians to detect and repair faulty section fast. Here are some hints about the number of blinks to Pansonic Plasma TVs. PANSONIC PLASMA TV:  MODEL NO: X24 _ C2 _ U2 _ S2 _ G20 _  G25 _ VT20 & VT25 Switch ON the set by its main power ON/OFF switch at its front panel [not with remote control], and count the number of blinks occur before the set shuts down. 2 Blinks:   15V SOS D_BOARD / P-BOARD. 3 Blinks:   3.3V SOS D BOARD. 4 Blinks:   POWER SOS P-BOARD. 5 Blinks    5V SOS D-BOARD. 6 Blinks    DRIVER SOS 1 SC BOARD OR D-SC FPC...

The repair of electronic equipment usually begins with its external inspection and diagnosis of the malfunction. In this case, you should inspect all the internal components of the SAMSUNG UE32F5300AK TV. Many visible changes in the state of the elements make it possible to determine the future direction of the troubleshooting. If the UE32F5300AK TV does not turn on, does not make any sounds when it is turned on, and also no indicators light up or blink on the front panel, there is a high probability of a malfunction in the  BN44-00605A  power  module  , which is made on the same board with the backlight LED power converter ( LED driver).   The 220V AC voltage is rectified by a diode bridge and filtered by electrolytic capacitors, on which a constant voltage of about 300v is formed as a result. The flyback converter, controlled by the S3310 PWM controller, provides the necessary rectified voltages in the secondary circuits of the puls...
