SOURCE: Hi, Re: JVC DR-MH30S Since yesterday the

Hi,

I am sorry to hear regarding the trouble.

What does the label show for a manufacturing date?

If your unit is at least 5 years old, then you are one of the lucky owners whose machine did not fail in the first 12 or 18 months. The problem has been so widespread that at one time JVC was repairing these out of warranty. To my knowledge they are no longer doing that. Most of the units that were shipped back to JVC had the power supplies replaced while others only had a few resistors changed, it depended on the particular revision.

In any case this would need to be professional serviced and in most cases would probably be more economical, based on the history of this model, to look into purchasing a new unit.

JVC had several issues with this model, one of which was the power supply not providing clean enough power. Other issues included firmware updates and other power related problems. Since your unit has gone this long, chances are there are components such as electrolytic capacitors that are enough out of spec that the circuits cannot function properly. You might be lucky enough to hit on one time when replugging might work, but it will get to a point where that will fail as well.

I am sorry to be a bearer of bad news, however if unplugging and replugging does not resolve the issue, you need to get the unit serviced / replaced.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Dr-mh30s. stops dubbing after a few minutes.


I seem to have sorted this problem for me simply by unplugging power.
I actually left it for nearly a week before plugging in again, but I'm sure a day would do, probably less.
Dubbed 2 playlists since, no problem.
Nice simple solution if it works.

Commonly this is cause by leaky capacitors in the secondry of the power supply SMPS ASSY.The PCB is located in the back right hand side of the unit.A visual inspection for any bulging of the capacitors will confirm this.
If you cannot change the capacitors yourself I suggest you take the unit to your local service center.

JVC DRMH20 "Loading problem"


voltages on CN5303 should be 12V and 5V. I found 5V to be2,5....3V.Check input of regulator MM1665A(should be 6V). If 6V ok,remove connector CN5303 and check if 5V ok.If so,here is my way to fix this "loading" problem.(create a new regulated 5V circuit)
Replace C5206 with 1000uF/25V,C5306 with 100uF/25V,isolate anode of D5213 from transformer,
wire one and an half turn around transformer,connect one end to ground and the other to the anode of D5213,remove MM1665A and replace with 7805 on appropriated radiator.
Input on 7805 is around 11,8V reason why you need to install it on a radiator.
