Help me fix Remote controlled socket.
Okay so the word is about Remote controlled socket from Emos company.
The thing died when safety fuse in my house poped out, when I turned the fuse back on this remote controlled socket didn’t work. So it won’t turn on by remote controll and when i plug it in wall outlet and plug something in it let’s say a lamp, it wont turn on.
I am noob when it comes to fixing electronics but currently I am trying to test components to see what could of died so i can maybe replace it also I always wanted to have some basic knowledge in repairing electronics becouse it is so usefull.
I have few questions:
What is this thing with Z1 mark on it, is it Zener diode? If it is why is it diffrent than normal one? When i test it with multimeter it gives me 1700 in one direction and other direction 700, is that okay?
I guess this is Ressistor with letter R value of 564 ohms but why is the one next to him missing his value and is white (or the sticker just went off) also i tested both with multimeter and both are not showing any value I guess they are dead, interestingly they are connected in series to this yellow thingy on other side, I guess it is capacitor becouse there is small C1 next to it, you can see the shape of it in pictures down. I guess then the capacitor is dead also.
Is this capacitor? Becouse it’s so small, anways i see the solder on it looks bloated or maybe that capacitor is dead? If it is capacitor where can i find these little capacitors to buy or how do i find out it’s value (desolder it and then measure its capacitance)? Problem is I can’t test capacitors becouse I dont have the capacitance tester.
What is this? First time I see it, also tested it with multimeter both directions not giving me anything.
Here are some more pictures:
If we fix this than amazing, It looks simple becouse it is only a Remote controlled socket but PCB looks so complicated to me with so many small parts and even big ones I dont know the name…
But in order to test the components I need those questions I asked answered.
Anyways any help is appriciated, thanks.
