Question about JVC TH-C50 System
Not that it matters I guess, but we have a JVC Th-C50 and it... just won't turn on now ... Not sure what's up, worked fine last night -- red light was on standby, no big, came home from work and it wont turn on. we've tried plugging it into different plugs, we've tried separating the subwoofer and plugging that in ... also nothing. The whole unit seems just dead... and not sure what else to do. We're looking into getting another system probably tomorrow - but my husband wants to try and fix this one... any tips on what it could be? I read one comment on amazon about this unit -- a guy said he had the same problem with it. We think the subwoofer is fine -- but the main unit dvd/receiver doesn't seem to be getting any power. Anyways.... any help/tips you can give is much appreciated.... thank you!
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.

You can order the fuse from JVC part # QMFZ059-1R0-E $8 after shipping.

I have a TH-C30. I had the same problem where the unit just stopped working - no standby light and no recognition of power at all. After checking this forum and another, I opened the unit, found the ceramic fuse where the power comes in and went to Radio Shack. They have a T1AL250V fuse pack that is a 1 amp, 250 volt, 5 X 20 mm SLOW BLOW glass fuse which is a better fuse for this common problem. Their RS number is 270-1063 and a pack of 4 costs about $3. Put new fuse in and the problem was solved.
The repair took minutes - 3 screws on the back and two screws on each side. Lift the cover from the back (it is slip-hinged on the front) and replace the ceramic fuse. It slips out with a little help and the new one snaps in place.

One thing you can try, that will probably fix this bug for good: Install a "slow-blow" fuse instead of the standard one. The "slow-blow" fuses are made with a little piece of fabric, (of some sort, probably asbestos), stuck into the center of a coil of wire that makes up the fuse. the purpose being; the fabric prevents the fuse from overheating 'instantly', instead, it takes it a couple of seconds to blow at the time of an "over-draw" or "in-rush" of current. therefore the fuse won't be as susceptable to blowing out from a mere voltage spike. Just be sure to get a slow-blow fuse that's of the same, (or within 10 - 20%), value of the original fast-blow fuse, (e.g. fast-blow fuse = 10A @ 250VAC, then slow-blow fuse should = 10A - 12A @ 250VAC). I hope this helps!

I have the TH-C50 and my unit would not start. I did what others advised (above) and installed the new fuse and now it's working perfectly.

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.

You could pull the cover off and check the fuse (Make sure it is unplugged first). If it has no indicators on it is likely in the input side of the power supply (Fuse, transformer).

No sound. The system cord and/or speaker cord is not connected. Check the connection.
The audio cord is not connected to AUDIO IN (VCR)
and/or DIGITAL IN (DBS) correctly.
Connect the cord correctly. (A pg. 13)
An incorrect source has been selected. Select the correct source. (Apg. 17)
The decode mode is not set correctly. Select the proper decode mode. (A pg. 35)
Do you think the powered subwoofer itself might have a power problem? Check its cord.
