My sister in-law dvd player get broke and he ask me to look into his player and whether it is possible or not, to fix the player.
here is the picture of her dvd player
brand: panasonic
model: DVD-S35
first thing we need to do is to remove the cover of the player.
once its remove, observe for any possible cosmetic damage or physical damage to the board.
usually, electrical appliances consist two or more electrical boards which are analog board and digital board.
Analog board is for power supply (to supply power to the main board to do it actual function) and usually consist of power conversion and step-down of power through power converter (diode rectifier usually) and transformer.
most common problem with appliances not working (no power) comes from this analog board. Especially fuses, capacitor, thermal resistor or diode rectifier.
Working analog board (supply board) usualy working to convert power to another form of power required by digital board. Commonly, the transformed power will be feed to digital board to do it function once voltage and current is tranformed to the desired one in analog board.
digital board usually difficult to get damage unless we abuse the appliances or use in the wrong way.
Now, lets focus on this dvd-s35 player. from my observation on analog circuit, it is obvious that some capacitor show some sign of damage.
There are four of capacitors show leaking on its body. take note of the value (voltage rate and capacitance value).
other measurement not showing any sign of problem to the board. continuity test to the fuse, life connection route, neutral connection route show good result, meaning that no problem with the part.
So, those damaged capacitor are removed from the board and the healthy one are soldered to it.
Then, board are installed back to the dvd player and test.
testing show that the player regain its life and working again.
So, conclusion!!, do not throw away your old electrical appliance before checking it..it might be just simple problem. or maybe just some damage to the part which are cheap to replace instead of buying new appliances.
Thank you and good trying
