Question about JVC DD-3 System
Last week my jvc dd 3 stop working.
I have it 1,5 year now.
No red standby light anymore on my tuner and no green control light on my subwoofer unit anymore.
It was playing on the background very low volume and sundenly it stopt.
I had a usb stick in it to play music from it. ( did that already alot of times)
I cant see any glassfuses or something like that on the outside of the machine.
Please help me fix it

SOURCE: subwoofer not powering up
I could either be the sub or the main unit. The main unit actually sends a signal to the sub to turn it on so if that circuit is bad in the main unit the sub is never going to come on. I've also seen bad cables (You'd be amazed at how stubborn people can be when din connectors don't cooperate).

I had the same power problem with my th-c50. In fact, this is a common problem with this model Home Theater In a Box (HTIB). The issue truly is the fuse. All you have to do is take the cover off and replace the fuse. There are approximately 8 screws total to take the cover off and you can do it with a standard phillips screwdriver. Once the cover is off, the fuse you need to change is underneath and slightly to the right of the power input (if the box in on your lap with the front facing away from you). The stock fuse is a ceramic, white fuse and if you aren't familiar with fuses, it looks like a very small cylinder. The model number is T1AH250V. These numbers mean that it is a 1 amp, 250 volt ceramic fuse, 5 x 20 mm in size. The fuse is held together by four metal posts. Bend the posts back to take the fuse out. Go to Radio Shack or your local hardware store and get a replacement fuse with the specs above. The problem that I had is that none of my local hardware stores had a ceramic fuse with these specs, only glass. I bought the glass fuse anyway (T1AL250V) and it works beautifully. Be sure to buy a "slow blow" fuse instead of a "fast acting" as they are more durable. Insert the fuse into the slot, tighten the clamps, put the cover back on and your done! It doesn't take too long. Hope this helps.

I removed the cover from the receiver and check the fuse with a meter. It check fine. Reassembeled the unit, plugged it in, powered the unit and ALL IS FINE. I don't know if the fuse had worked itself loose (don't really think so) or just lucky.

It is possible that the power supply, and or the internal amplifier has some components that have failed. The unit will have to be serviced.
Get in touch with JVC to find out if your unit is still under warranty, and to find out who is their authorised service rep for your area.
