ELECTRONIC WORLD EXPERIENCE

LEARNING LOOK FOR ANY AUDIO AND TELEVISION
Back Again in my experience of electronic learning
Once I was able to assemble an audio and a little later I managed to learn to repair the damage that often occurs on the audio device:
1. Total dead> his usual damage to the adapter block (if it continues it means breaking fuse is faulty transformer / short-circuit, and if transformer good check on the diode and its up to the adapter output elco out 12 DCV,
  when the output voltage is normal but it still means damage to the die block amplifier transistors / ic there is a short-circuit.
2. Ringing sound> Usually the damage on the block amplifier, if amplifier using transistors that there is usually a second transistor is defective, if the switch transistors do not forget to also check diodes and transistors his others.
3. Small voices (treble voice did not come out)> Mechanical damage to the Head of his usual dirty / hungry, if replacing the head do not forget to press the same rubber wheels replaced her.

DVD & VCD

     Then I learned to improve the audio from my starting to learn to improve VCD / DVD Player
Before I learned to fix VCD / DVD Player I have learned its workings and its block diagram in order to predict damage to VCD / DVD.
How a VCD / DVD> Removing Sound And Picture the beginning of the process works cassette disc VCD / DVD is read by An Optical Components / Head on VCD / DVD and then in the process by impek sa
aligned below the picture diagram

 > BLOCK ADAPTER / POWER SUPPLY
    Voltage: - Output 5 VDC
                 - Output 8 VDC
> BLOCK MECHANICAL
     - Dinamo cd disc drive
     - Dinamo optical drive / head
     - Dinamo close the drive door open da cd
     - Rubber dynamo
     - Optical / Head
> BLOCK IMPEK
     - Input voltage to 5VDC and 8VDC impek
     - Voltage Dynamo cd and Optical Disc Drive
     - Voltage Dynamo Activator Open / Close
     - Output to Optical / Head
     - Input Vidio and Audio
     - Output to Control Panel and Display

DAMAGE SYMPTOMS DVD / VCD
1. Dead> Damage to the block Adaptor / Power Supply, Voltage Output must Exit 5 and 8 DCV DCV If    not exit normally broken FET Transistor / Diode
2. Picture and Sound End-End> Damage In Optical / head is weak, the optical beam to Memabaca It Less Maximum disc cd
3. Can not Open / Close DVD / VCD> Damage to Rubber Mover Dynamo Open / Close Mechanics suda stretchy, rubber good if it could be too weak Dinamo.
4 Can not Read Disc Cd> Damage Usually In its Optical Cable Optical Cable And if Good means Damage Optical / head


Until the first day I continued here again to learn the story of my experience in the electronic world. If there are deficiencies Please regrettable. Do not Forget To Build Morale maencari comments Particularly in Science Electronic Technology, THANK YOU
