JVC DRMH20 "Loading problem"

Unit flashes 'loading' continually on power up. I have been led to believe that this is a power supply problem that can be fixed by changing a couple of caps on the power supply board and adding a resistor to prevent the problem re-occuring. Can anybody supply me with details of the modifications required?

    I have the exact same fault with my machine. I rang JVC Customer Services and an adviser knew of the problem straight away and advised me to send a copy of my reciept to JVC HQ and they would provide a label send send back for a free mod.

    After 2 weeks, I got a letter Friday 16 Nov 2007, basicaly telling me it WAS NOT a common fault on this player and as the player is over 2 years old, take it to a repairer and pay!!

    Great customer service I thought, thanks JVC. I have 3 other JVC products, but it goes without saying, I will NEVER buy another JVC product again on principal.

    I had the same "loading" problem after 3 years from a DRMH20 that cost me £399.

    I contacted JVC by email with a copy of my reciept (warranty expired 1 year ago) and they asked for a letter as they couldnt open attachments?!?!?!.

    I sent a letter and the reply was that they were concerned (not as concerned as me clearly) and said they would not pay for any repairs due to the age of the unit. I explained to them that this appears to be a worldwide problem but they still wont help out.

    This is the first and last JVC product i will ever buy.

    Loading Problem

    Zojuist deze recorder weer
    aan de praat gekregen na de bekende loading problem.

    Ik heb originele elco's
    gehaald tegen 49 euro vergoeding bij Techno Groningen B.V.

    Van der Hoopstraat 6

    9716 JM Groningen

    [email protected]

    Dat komt omdat ik die elco's
    niet echt kon vinden , het zijn aparte dunne lange elco’s met temp code 105 graden. Die gewone 105 graden types kunnen er niet in.

    De hele rij secundaire grote
    elco's vervangen, de primaire 22 uf vervangen door 47 uf en secundair nog eens
    470 uf .

    Vevangen dus:

    c5318 470 uf 16 v

    c5203 680 uf 16v

    c5204 1200 uf 16 v

    c5205 1500 uf 10v

    c5206 1200 uf 16 v

    c5208 1000 uf 10 v

    c5209 1500 uf 10 v

    c 5309 470 uf

    c 5340 en c5307

    Uiteindelijk was in ieder
    geval echt zichtbaar defect de c5318 en de c 5340. c5340 voeding van de dvd recorder. Er stond op
    die plug die naar de recorder gaat een 600 mv sinus puls op die voeding, en dat
    was de boosdoener kennelijk want nu komt ie na starten weer uit de loading lus.

    Groet, Rob Hilhorst,

    hey gurilla, I have the same problem and can see two damaged capacitors on the power board, c5318 and c5319 did you manage to fix yours and how if so, cheers

  • casandre Sep 21, 2008

    yes i have the same problem with my DR-MH20S, we used it approx. 5 times...the display just flashes "Loading" and nothing else happens... though there is no dvd in the unit... no buttons seems to react at all, pluging and unplugging power does not help neither...! any fix to that...? seems that i bought the wrong model...My previous DVD player was a JVC too... it did exactly the same tric after a couple of months.... can't reccomand these models....

  • casandre Oct 14, 2008

    Display flashing "loading" is apparently a common issue with jvc drmh20 models... the worst of it is that the local jvc denmark does not even react to my request! i am impressed by the vey bad service level of jvc.

  • Clivespana Jan 05, 2009

    The display flashes "Loading" continually, the on/off button does not switch off the unit "loading" shows continually until power plug is removed.

    This happened 6 months previously and a new power regulator was fitted. Our power recently went down and ever since the unit will not load.

    If I mark as #1 the beginning and #2 the end, as I wire it clockwise, which number must be connected to ground? (I assume it's not the same either #1 or #2)


    P.S. Of course, got the same problem and found both condensers "burnt".

  • alex-monk May 13, 2009

    I had the same problem with the DRMH-30. I contacted JVC and, even though it was out of warranty, they delivered a replacement to my home, free of charge. So I don't agree with the poor service from JVC UK. Needless to say the replacement lasted only several months before experiencing the same 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.

This is a well-documented fault. In the USA power lobbiests got JVC to recall the units and fix the problem. The fault is a small component that was wrongly specified - when it reaches a set 'maximum' temperature is fails and causes a protection shut down. Over time it fails to allow start up. It is worth finding your nearest JVC approved repairer (if it is out of warranty) and have the recorder repaired.
Here's the official help as in the good old USA -
A limited number of units of certain models of DVD recorders (Models-DR-MV1S, DR-M10S, DR-MH30S, DRMX1S, SR-MV30U) have experienced the symptoms described. While manually resetting the unit, as set forth in the question, restores normal operation, the symptoms may reappear. JVC has identified the cause of these symptoms and will make the necessary adjustments to affected units to eliminate the likelihood that the symptoms reappear. Adjustments will be made free of charge at JVC Factory Service Centers. Click the Factory Service Center link at top left of this page to obtain your nearest location. Please call 1-800-252-5722 and select option 4-3 if you have any questions regarding this process.
Presumably the UK JVC Centres will also carry out these free of charge ! NO SUCH LUCK! We are 'Rip-off' Britain - as always.
Here - for your further understanding - what happens in the UK:
Repairs to JVC products are carried out through the JVC dealer network. All JVC dealers are aware of the technical support that is available from the JVC Service and Engineering Division if required. Unfortunately JVC UK are unable to quote the repair rates for JVC independent service dealers. We recommend that you call these dealers in order that they can communicate their repair charges to you.

The JVC Service Centre in the DE postcode area is: Trade Services, Holbrook Rd, Belper. Tel: 01773 822073

Repair Dealer : Relliance, Babbington Lane, Derby. Tel: 01332 363488

Good luck - once it's fixed, keep the receipt and guarantee, just in case.

The display flashes 'LOADING' when finalising after 20 seconds.

How old is your unit ?

After Loading message what are you getting ? any error message .

Try this unplug the unit for 20 minutes and plug the unit after that time this will remove the error .

Jvc dvd vhs burner dr-mv1s and dr-m10 loading continues to flash

if you have a jvc dvd vhs burner dr-mv1s or the dr-m10 with the loading that continues to flash with no control of the unit at all there is the first step to take witch is a master or hard reset. done by holding the stop and power buttons at the same time for 10 or more seconds till it powers of then on again.

if this does not work or has no reaction to the unit at all them repairs will have to be made.

i have scowered the internet for fixes for this issue and have found a few interesting things but nothing concrete at all. but lead me in the correct area of the issue. although jvc was fixing these for free at one time they are no longer servicing them under their "free fix"

the problem with the unit is the power supply and although i found that easily on the web. i could not find what the exact problem was untill i did my own diagnostic testing and found that capasitor c5207 on the power supply board was bad and buldging/leaking. it is a 1500uf 6.5v @85 degrees witch i used a 105degree due to the temp and relating the issue with a bad design flaw. so use the higher temp rating one to insure long lasting use.

don't forget to preform the master/hard reset previously mentioned above and you will be back up and running in no time.

good luck......

Loading keep flashing when powered on

Turn the unit off for about 10 minutes and then turn it back on. Then just wait for 'Loading' to go out - it can take 15 minutes or more. Be careful as the power supply on mine blew up after 2 years and I had to fit a new one £95.

Loading problem

kinda heath robinson affair this one.
If you buy a usb to IDE adapter, they come with a 5v & 12v power supply.You need to open the unit and connect this to the dvd drive's power.
You'll know it's working if you hear hard drive activity.
The recorder will power down, then just power on and away you go !!
alternativly (not tested) get a ide power cable splitter, but the current might be too much

Continuous flashing loading

Same problem here. Nothing seems to work... Pressing any key makes no difference. Disconnected the power - nothing.

Loading fault

check power cables to dvd and hd. voltages should be 12v,gnd,gnd,5V with and without load. if voltages drops with load then fault is probably with caps. I changed one cap when voltage dropped in dvd powercable(5V). cost only 0,50€ to fix powerboard. there is a high risk for electrical shock so if youre not familiar with electrical devices and dont know how to perform these checking operations and so on... then PLEASE take your unit for professional
