20 Most Recent JVC DRMH20 DVD Recorder Questions & Answers

go to a computer shop and buy a kingston solid state hard drive-250 gig for around $65.00 aud next obtain a copy of win 7 with a registrable licence code and insert it in a cd drive turn the computer on and hold down the delete key until the bios screen appears move to boot tab select cd as first boot device , yes and hit the esc key turn off the computer then restart it the bios direct will activate the cd and load the program into the hard drive and you are up and running when finished , go back to switch off and do the bios start again and this time set the first boot back to hard drive A 250 gig sshd is equal to 500 gig disc type and will not fail as there are no moving parts

Thanks to Bogbrush (what a name!) above for the hint to check R5107 when the STRG6653 explodes, indeed it was open circuit. I replaced that with a non-SM component since that's what I had to hand, replaced the fuse (2AT), replaced the STRG6653 and replaced the mains rectifier since this looked to have suffered even though cold checks implied it was OK. Then rewarded with a fully working DR-MH200. I had already gone through the power supply replacing any capacitors which had gone high E.S.R, several had. The 27uF 35V capacitor in the primary circuit of most JVC DVD recorders is particularly prone to failure.

hi,

Try the following to reset the recorder
Remove the power from the wall out let and reconnect it after 5 minutes.
Press and hold the standby button, whlile holding the standby button press the STOP button for 3 seconds.
If this didn't solve your problem then there is some thing wrong with the main board. First of check the reset
ok

my machine just has loading displaying in a flashing mode

try switching your tv to pal instead of nstc you can do this in the remote menu .

You may want to check the digital converter boxes and make sure they have analog pass through, it should be listed on the box or the instructions. My Magnavox and Zenith which were bought about a year ago, do not have analog pass through.

Heres the english manual..

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.

I know of three people who tried doing this with discs purchased off EBay - and trashed their machines. Not recommended.

There´s good material on this topic on FixYa. Look for it under JVC DRMH20.

You can record sound on DVDs (up to 8x -R), CD data discs cannot be recorded on your machine.

gargame,

good day, if you already replaced the fuse and still keeps on blowing it again. you still have a short circuit somewhere within the power supply area or board.try to check if there are any other blown parts or slightly expanded shape part specially for capacitors near the power supply area .

2) If you do have multi tester and have some basic knowledge with component checking try to check the polyswitch protector, this is connected parralel to AC supply right after the fuse before going to voltage rectifier diode.

3) if it doesn't have a polyswitch protector check the polarity of your rectifier diode, maybe 1 of this 4bridged diode is shorted.

cheers,

A clicking noise when there's a hard drive present usually does not bode well for the end user. This noise is lovingly known as the "click of death" and it's name says it all. I'm wondering if maybe the hard drive has gone and the JVC's error handler does not allow it to progress past POST while there is a hardware error present. My apologies, I know that this isn't a solution, but hopefully this will at least help answer some of your questions as to what's going on....keep in mind that this is ultimately a guess, however, based on what I do know about electronics hardware.

First, let's see if the player tries to read the disc. Load a disc and listen. Does the player make squealing noises or is it totally quiet? Squealing noises may indicate that the player is trying to synchronize with the disc but can't due to an obstruction on the lens or in the laser path inside the pickup or a defect in the pickup. This can also be caused by an intermittent signal problem due to a faulty ribbon cable. Totally silent means that the photo sensor is not getting any usable input from the laser at all, meaning that the pickup is "blind" for lack of a better word. This can be caused by an obstruction of the beam by foreign matter on the lens or inside the pickup all the way to a marginal or failed laser diode and/or photosensor array. This can also be caused by a bad ribbon cable with one or more severed traces. You could try to clean the optics. This is the most common malfunction as far as i know in all disc players. It would involve taking the cover off and finding a way to expose the lense, and then cleaning it with a very gentle brush. some players have a cover for the lense that swings to the side during playing, this greatly reduces the chance of dust accumulating, but its still worth the try. If you actually see dust on the lense, then its just that simple. clean, close, play. Good luck

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 .

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

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

I had the same fault - only answer is to take/send to the nearest JVC repairer. (Cost me £68 which included a £45 service fee!)
