Re: No power to my cdj 200. I've checked the fuse
Hi and welcome to FixYa,
Based on your posts, a couple of possibilities:
it is a display problem. To confirm play/use the unit. If everything else works, then display problem is confirmed. This could be a backlight failure or supply to the display failure. If it is dim, then insufficient supply and could simply be a dropping resistor, voltage regulator or capacitor leak;
if other functions will not work, then it would be a power supply issue. Offhand, it could be voltage regulator and/or any of the multiple B+s outputted by the PSU.
in some other instances, this could be a faulty/leaky capacitor or a cold solder issue.
Either way, repairs call for voltage checks and opening the unit. This requires familiarity with electronic components & circuitry, use of a DVM and a soldering iron. Access to a Service Manual or at the very least a schematic diagram would be to your added advantage. Should you be uncomfortable with a DIY (do-it-yourself), then perhaps your best bet would be an authorized service center or a qualified professional.

You are dicussing about the microswitch that fitted on your CD payers' control printed circuit board; I understands. If so, it can be replaced. Microswitches are of many types with different sizes and pin confugurations. You just desolder it out from the circuit board, and go for a same type, both in size and confuguration. Keep a keen look at its height, whcih cannot be exceeded of the present switch fitted in your CD player. Insist on exact size, and go with that sample you have resoldered it out.
Microswitches are available easly, on all electronic sparepart shops, and are cheap in price also. OK
If the player have been dropped once, it could be a broken circuit board as the transformer sits in between two boards and the mounts for it will bend easily. Or the voltage selector switch on the back are in the wrong position.
no you cannot do that , the device works on 120v( 117v around me) , but it cannot be changed like that , you would need a trans former that breaks down the voltage to 120v
changing the fuse will not change the circuitry in the device
Hi there! The switches probably need changing on the circuit board inside the unit as they corode after time. Mine had the same problem lucky for me my brother is god with circuit boards and replaced all switches and now they work fab. Or you can bye special electric switch cleaner and clen te switches on the circuit board. Hope this helps.
