JVC dr-mv78 power problem

A few days ago, I went to turn on this unit and it appeared to be completely dead. I tried holding the standby/on button for more than 5 seconds without any results. I unplugged the unit from the entertainment center, put it on a table, took off the cover, front panel and then connected the power cord. I can see a small red light under the dvd player. I pushed the power button and the DVD eject button several times and started to hear a soft bumping noise. I tightened screw located in the same approximate area as the DVD eject button and suddenly the clock flashed dashes several times and the vcr head moved. The clock dashes turned solid and when I hit power the "HELLO" appeared. Everything was working. I plugged it back into the entertainment center and everything worked fine. Yesterday, while I was at work, the power went out at my house. When I got home the unit was dead again. I repeated the above steps and it works again.

Is it a power problem? What should I do to fix it? Any help would be greatly appreciated.

    My problem with this JVC DR-MV78 unit also occurred after a power interruption. It will power up and displays HELLO but that's it. After about two minutes, it shuts down. Totally unusable. I will try the above.

SOURCE: VHS won't work

Had the same problem on my JVC vcr/dvd combo unit.
You need to turn off the timer function. I did this by making sure my remote was in the "VHS" mode...turn the swith from TV to the right (found on the remote in the upper left corner...an then hit the "vcr" button. Then point the remote at the VCR unit and hit the No. 4 button (timer turns off). Your unit should not have the red timer displayed and you should be able to play your tapes okay.

Hope this helps.

The processor has some garbage in it, and if you unplug the unit from the wall for 40Min., it will reset back to normal.

Tip

TomTom GPS battery discharge when off


With the TomTom GPS units, if you use it infrequently, you may often find the unit has a dead battery when you go to use it.
This is because turning the Tom Tom off normally with the power button doesn't actually turn it off fully, but instead puts it in a standby mode.
Even though the screen is off and it appears to be shut down, it's still using some power to maintain configuration settings.

If you know you won't be using it for a long period of time, you can press the reset button on the bottom of the unit (this can be done while it's off), and it should put it in shutdown mode, where the battery will not be drained so rapidly. If you do this, you can confirm it's in the shutdown mode by tapping the on button. This normally will power up the Tom Tom, but in the shutdown mode, it will not do anything. To wake it up from the shutdown mode, press and hold the power button for a few seconds, at which point it should turn on and greet you with the Tom Tom drums. It takes quite a while to boot up from this mode, which is probably why they defaulted to the suspend mode instead of a true "OFF" state.

For some of the newer units, they've omitted the reset button, so the process is a little different. Instead of pressing the reset button, do the following:
with the unit on, press and hold the power button. The shutdown screen should appear, but continue holding down the power button for another 12 seconds after the screen turns off. Timing is a bit touchy, because if you hold it too long, it'll end up just rebooting, and then you'll have to try again.
If you're successful in the shutdown, you can test it by briefly pressing the power button. It shouldn't turn back on with just a short press. If it comes on with the tap on the power button, you'll have to try again.

This whole process is a bit of a hassle, and extends the turn on time greatly, so you'll want to plan ahead when doing this, and just shut off normally if you expect you'll be using it within a couple days. However, the long boot up is preferable to having a completely dead unit when you need it, especially if you're away from a power plug...

Try a hard restart,

To reset the iPod Touch, press and hold down the Sleep/Wake button and the Home button simultaneously at the same time for at least ten seconds, then the LCD display will clear and the Apple logo appears on the black background. When Apple logo appears, reset is done.

Also be sure to leave it plugged in to charge for a few hours - you may have completely drained the battery.

Stuck on Standby


Do a hard reset. Unplug it from the socket, the DVD and leave disconnected for 4 hours. This may or may not help, but it is a necessary step to restore all internal software codes to their factory settings.


Hope this may help;

JVC DR-MV1S won't turn on.


the problem is power failure in the untit's system like faulty capacitators....which when they fail will not allow the correct amount of electricity into it's main operating "motherboard" of the dvd and or vcr....if not...try to hold down the power button next time it goes off...for a while and see if it turns off again...and see what happens.

DVD player stuck in standby mode


Bad caps in the power supply is causing this. C17 (10v,470uf), C17,c14 (10v,1000uf) and C18 (10v,470uf). Replace with same capacitance values but 25 volt rating 85 C. Just fixed mine half hour ago works great.
