Samsung dvd sh893m

The built in dvd drive of the Hr-720 is very useful to be able to copy videos from the hdd to dvds. After a few months, my dvd rw refused to format rw disks and gave system error messages.

Managed to fix the problem by doing the following:

Remove the top pvr cover. Then the dvd drive cover is very easy to remove, only 5 screws and it is off.

Cleaned lens with cotton bud + cd cleaner fluid

Sprayed lens assembly traversing rod with wd40

Adjusted dvd potentiometer (circled in red) - turned +540 degrees clockwise = 1.5 turns

The significant tweak here is the pot adjustment. The idea is to reduce the diode resistance to get more current through the dvd laser = more power. I noticed a difference straight away with the first tweaks of 180 deg at a time, the dvd would load more quickly and several formatted successfully. The pot should be set to between 4k-6k ohms, but there is no obvious way of measuring this.

So Im hoping this should be ok now. It is worth trying as the dvd drive in its previous state was useless electronic junk anyway, although the hdd has always been fine.

Hold Play/Pause down for 10 seconds

you need to connect your wire to VCR out put and connect the other side to DVD input don't forget yellow to yellow, red to red and white to white if you have 3 prongs wire.

This message is usually indicative of a HDD failure. Open the access door and make sure the HDD is properly connected. In rare cases the HDD is fine and the interface controller has failed.

This problem is down to failure of the laser and an only be solved by replacing it. Samsung are aware of this fault but will only offer a free replacement if the unit is still covered by it's warranty.
They do offer a replacement service but charge £94 for it.

laser is getting weak

I had exactly the same problem -- error message of "This disc can be neither played nor recorded. Please check the disk [EC:0207]" after the machine had been working fine for a year. I downloaded the latest firmware from the Samsung website, burned it to a CD-R disk (took three tries until the DVD Recorder recognized the disk -- worked when I used Rocio CD Creater software), then loaded the firmware updates to the DVD Recorder. On the Samsung website you can retrive the firmware update instructions as well. I had to perform the firmware upgrade several times until it successfully updated both the system firmware as well as the disk firmware. After successfully updating both, the Recorder now recognizes the DVD-R disks and I was able to resume recording. I have however, noted some choppiness with the playback of the newly recorded disks. Other than that, the firmware upgrade successfully resolved the problem.
