Panasonic DVD-RV31 DVD Player - Answered Questions & Fixed issues

There is a solution but it takes a little care because the wrong thing touched will give you a shock. Just stay away from the unit near where the power lead enters the unit. OK. remove the top of the unit, place a disk in the unit press play and gently give the DVD a gentle push in a clockwise direction. This disk should then get up to speed and start playing. It also unlocks the error. No guarantees with this one some work, some don't. I hope yours does. BMW

Try Cleaning the lens.

The TV may have an adjustment or not to either center the picture up/down or adjust the overall height of the image--some have it and some do not.

Hi smcenaney,
If you have necessary tools and test instruments, know safety precaution in basic troubleshooting try the steps below to solve your problem.
Assuming that the disc is good.
1.Clean the lens. - Sometimes because of dust the lens can't read any disc. Try clean the lens by soft cotton buds. Be careful while doing this.
2.Replace the ribbon - Check the ribbon connected to the lens from the main board for scratch, damage. Once it has an open line then of course the lens can't read the disc. Also try to erase the contact by pencil eraser. If you've done the steps above and the symptoms still there then the next step requires you a little knowledge in soldering technique and reading the ohmmeter.
3.Check the motor - Check the motor that spin the disc with an ohmmeter. You can test it using the ohmmeter (x1) even it is connected on the lens assembly.Good motor - reading should be fairly high and it will spin. Bad motor- reading will drop to low resistance and will not spin.
Hint : 50% of my repaired unit the above parts are commonly caused of the problem.
If you confirmed that you have a defective motor then replace it with a new one. Before replacing the new motor you have to check the clearance of the disc holder with the old one. The clearance should be the same as the old because if not the lens will not read the disc if it is too far or too close.

You may also replaced the entire lens assembly if the above solution didn't cure the problem.
Hope I helped you.
Have a nice day!

What is the last thing you did before this problem started?

No, there isn't a reset button in it. The player is stuck because either the button for the fast forward is stuck or the processor itself is defective.
The button is relatively easy to fix: open the case, take off the front to access and remove the button board and then fix it - it's a dome switch so just take the dome off, clean the contacts and put it all back together (some soldering will be necessary).
If it's the processor then the player is dead - unfixable.

Hi , Just simple ,
option 1:
Please open case and clean the lense
or
option 2:
use good lense cleaner cd with liquid.
just drop liquid on to cd cleaner ( excatly on brush)
then you run.
it will solve your problems.

i don't know

It is due to the reading LED inside it, you just check whether it is working or not.

Yes you can. It is called the aspect ratio. You will find it on the menu of your DVD Player. Goto the menu without a disk in the player.
You can also change the aspect ratio on some TV's to match that of the player. See your TV menu or user manual.

1) Dirty or poor pick-up.
2) Sled motor sticking (bad sled motor or contaminated lubricant on the sled rails).
3) Faulty spindle motor. (especially if spindle motor is spinning with top off and no disc inserted).

DVD-RV31 also tends to suffer from dry joints to the surface mount IC's and that could cause all sorts of erratic operation.

try cleaning the scanner eye with the cleaner disk

You can use a laser lens cleaner to clean your lens.

Bye a new one

First try resetting the player. Unplug for 1/2 hour-1hr., press and hold power button for 3 seconds, wait 1/2 hour, plug back in and it should work. Otherwise you can pry open the door with a paper clip. Slowly pull door as far back as it will go, then press eject button and see if everything aligns itself back on track.

have you used a cleaning disk to remove dirt from the scanner eye?

You will need to get a can of the compressed air or use an air compressor if you have one. Then remove the housing cover if you can and use the compressed air to blow out any dust and debris inside the unit. Also blow air into the inside of the dvd tray. This has been the common fix for the HO2 error on your DVD player. You could also use a DVD lens cleaning kit.

If it only happens with one disc, try using a Disc Doctor/Skip Doctor on it. These instruments will repair scratches and depending on the disc, repair pinholes in the disc. Usually it's just polishing the surface of the disc. Some instruments totally resurface the disc by stripping off a thin layer of the disc to remove scratches and other damage. (Used game/music stores will do this).
