Problem is caused by unstable 12v supply to HDD.

To fix you need to replace the 1000uF 25V capacitor in the power board. The failing capacitor has a expanded casing and there was two of these in my daughters unit.

Worked OK once I replaced the 2200uF and the 1000uF capicitors.

    Yes, this is a common problem, caused by cheap capacitors in the power supply board (back left-hand corner of the case, next to the DVD player). Replacement power supply boards are available for anyone who is not up to the soldering. These cost ~$US50, compared to a 2 or 3 dollars total to buy the two capacitors (which must be the low ESR type, which are readily available from electronics parts places). The only tricky part to replacing the power supply board is levering the board off a 16-pin plug. Just level it a little at a time and line up the new one properly and gently but firmly push it on (it's not difficult). I replaced seven capacitors in this region of the board (C121, 123, 124, 125, 133, 134 and 135) for $8, just to reduce the chance of having to revisit repairs in the near future.

Hi Graham,
I found I had to replace all three of the 1000uF caps and the 2200uF cap. As a general rule, I just replace them all in SMPS's and it works.
Testing the old caps reveals most of them are way out of toleranve and/or have high ESR's.

My LG RH397D will not play a disk. It gives a navigation error.

Does not play disc

  1. No disc. - Load a disc into the tray.

  2. Disc has been loaded upside down. Place the disc with the label side up.

  3. Disc region code does not match region code of the player.

  4. Disc type is not the correct type to play.

  5. Disc is damaged or dirty. Clean the disc or try another.

  6. Moisture may be condensed inside the unit. Remove the disc and the leave the power on for one or two hours.

    See the diagram attached.and if the problem persist. Lube the plastic parts with small grease or vaseline very carefully

Can't play USB MP4 on LG RH397D

The LG RH397D only supports MP3/WMA/JPEG/DivX image and audio files from a USB drive. There is no firmware update that changes the supported file types. You will need to convert the MP4 to a supported format. The manual for the RH397D is available from LG: /

I wish that I had better news for you.

My LG RH397D HDD wont recognise dvds any more

The only thing you can do is try a DVD cleaning kit and follow instructions, if that fails the laser pickup assembly will need to be replaced, but this would be to expensive and far cheaper to replace the player.

I have an lg RH397D dvd recorder - the lcd just says Hello over and over and will not turn on.

You need to replace faulty cheap capacitors on the power supply board (one or two will be bulging on the top, with or without a brown exudate; see picture). This costs only a couple of dollars, or you can replace the power supply board for about $50.

Hi i have an lg rh397d and the hello lcd just keeps playing but unit wont turm on?

There is a bad capacitor in the power supply that controls the 12V going to the HDD and DVD player. When you turn it on, the 12v drops to 7 volts and the unit turns it self back off. You just get the "hello" message briefly. You need to replace the part (1000uf, 25v), it's probably showing signs of bursting at the top or bulging.I noticed this in a 397d that came to me from a relative. I've just replaced this part in it and it's come good again.See bad caps at for why this happens.

Cannot playback dvd-r on lg rh397d after recording from hdd. message is 'cannot playback due to navigation error' please help

When you burn a DVD, it is ONLY playable in the RH397D.
Buggy menus - and no way to flash the firmware.
Terribly designed remote.
HDD never seems to spin down, no matter how long it sits.
Doesn't play XVid.

I was a bit disappointed with this product. It does do, what is listed on the box, and one can't be too disappointed with that.
