I have destroyed two of these machines to remove my precious CD's. I did discover this today:
1. There is a fuse but it is soldered onto its circuit board.
2. There is no easy way, like using a paperclip on the old computer cd-rom drives, to release the cd/dvd tray. However, when I destroyed my second player, I noted there is a rather large piece of metallic tape on the bottom of the player to the right side of the front of the drive on the metal bottom cover plate of the machine. It is covering a slot about an inch long. If you carefully remove the tape and use, say a phillips head screwdriver, starting at the right side of the slot as you face the front of the player, you can slide a plastic bar that will free-up the tray slightly allowing one to pull the tray out and save the cd or dvd. I would do this with the player upright but hanging over the edge of a table so that the freed cd doesn't bang around against something in the process.
For what it is worth, I hope this helps.
Yamaha should be ashamed of producing a product at this price point with an issue like this. At the very least there should be a fail-safe way of removing a cd/dvd from the drive regardless of the issue with the electronics or drive mechanism.

1. It's more likely the problem is a broken power cord or dirty power switch. If you've been in the habit of yanking the cord to unplug the unit instead of pulling directly on the plug, or somebody tripped over the cord, the power cord is probably broken right at the plug.
2. Changing a blown fuse without finding and repairing the fault that blew the fuse will only give you another blown fuse. It's not like the old farmhouse with too many things plugged in on the same fuse... A blown fuse in audio equipment is usually the result of a shorted speaker driver transistor. The transistors come in pairs; if one is bad the other has been overloaded and should be replaced also. That's a job for an electronic technician.
Hi welcome to fixya do you mean the dvd player won't turn on ?.if no power at all you will need to unscrew to open the cover.now if you want a DIY... you must have the necessary tools like phillip screw driver and digital tester. then you must check first the fuse at the power supply unit if blown. the power supply, this is where the power cord connected if the fuse is totally burned before you replaced the fuse you will need to check shorted diode and transistor which cause of the fuse to blown. and then just replaced the fuse with then same rating capacity that is label in the board. thanks hope this can be helped, feel free to ask further solution just let me know if this is what you asking for, i'm glad to help you to diagnosed and fix the problem.
Take the top off the unit and check the AC fuse for an open condition, The fuse is near where the power cord enters the unit. If the fuse is blown then there is a problem in the primary side of the power supply.
You have a power supply problem, if the cord is detachable from the player make sure it is snug tight, next pull the cover off and follow the cord to the power supply board to see if the fuse is blown, the other thing I come across is a bad capacitor near power transistor but this will require some technical know how. One final thought, check your unit on another wall receptacle.
If the unit is competely dead, then you may of blown a fuse or the power supply has failed in the unit. If you take off the top of the unit while unpluged check the fuses near where the power cord attaches to the inside of the unit this is the power supply area, If you have indicators lit or the display is coming on then the unit may have a bad power supply or the System control board has failed. It which case its cheaper to just purchase a new unit.
The outlet that the unit plugs
into... Is it 'hot'? Plug in a known working Table
Lamp. If you have power, the problem is the unit.
Where the cord goes into the unit, locate the Power
Supply. Carefully check for any cracked, blackened,
or broken components. My educated guess is that
a small fuse blew, as did the Metal Oxide Varristor,
which is either a large blue or red disc shaped component
near the power transformer. If the fuse is blown black
inside the glass, this indicates a short, and would require
an Ohm Meter to locate it. If the fuse is blown so that
the element inside just melted open inside the glass,
this indicates an overloaded condition, and would require
that the fuse be replaced with a rating 1/4 amp greater
than the original fuse. Why? because most fuses are
under rated to insure that they will need service to keep
people like me from starving! Trust me on this one.
Check to make sure that your power supply printed circuit board is getting power from the wall socket and if so, check for any blown components, most likely a capacitor on the power supply circuit board. I hope this helps. Good luck.
1. Check that the AC outlet is working.
2. Check that the AC power cord is ok with no damage.
3. Unplug the unit, remove the cover and check for a blown fuse.
If blown, replace with a value that is the EXACT value as the original.
4. If the fuse blows again or the unit is still dead, you most likely have a problem in the power supply section.
In that case, you'll need to take it to be serviced.
Please let me know if I can be of further assistance to you.
hey did you check the fuse in the relay box on the yellow wire?
if you cant get it fixed then sell it to me real cheap my board went out on mine and kenwood dont sell boards and the repair center cant fix mine.
