Samsung dvd sh-855 i have the same problem wiht freezes when recording on timer mode.Recording in timermode with TV on is OK. But only connected whit HDMI cable, Component is OK in all modes!!!
My recorder is a XXE model = scandinavian.
Do anyone have a solution Please

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.

Hallo everybody,

this guy "mysus" is a genius! I have had above problem on a Samsung HR-725 (160 Gb Version of the HR-720) now for approx. 1 year. I´ve called the Samsung Hotline and tried other dealers - nothing worked. Today I came accross this help and tried it out immediately - and it works perfectly. However, you do need to know a little about PCBs and electronics.
I used a variety of different -R DVDs and they all seem to work now. Many thanks once again for this fantastic link.

bad micro probably. could be power supply,might be better to replace http://www.shopjimmy.com/

Hi, Check the settings in the TV menu. Set the sharpness abit higher. Also if you have already you need a set top box (PVR) to view digital signal and to record it as well. Good luck.

Process Standard Offset

Press the 'pscan' button on the front of the recorder 3 times and the picture will come back. This is a little sod as you only need to catch the pscan button once - if your TV doesn't support a progressive scan your picture has gone....

Hi.


Here the firmware upgrade.
