Question about Samsung DVD-VR320 DVD Recorder/VCR
I had the power go off last weekend and when it cam back on the player just wouldn't work, I checked and found power being received as the optic cable outlet behind the unit had the light on but there wasn't anything else happening.
If you could help me find the problem and a solution to the issue, it would be most appreceative.
Hi we had a power failure for several hours now my Samsung DVD/VIDEO player seems to have not power - do I chuck it (only 18 months old) and buy a new one or how do I fix it?? HELP model - VR320
Local repair shop said it's un-econimical to repair.
Admitted they had no service manual.
Said they could 'have a look' but likely repair cost would be over $300. Charged me $50 for quote. Useless Gits.
My opinion & findings.
Power supply sensative to spikes.
I Suggest a power filter in-line with unit.
Disconnected all sub-boards from main.
Hiccuping PSU (5v wobbles between 2&3V).
Replace switchmode IC & feedback IC. No change.
Eventualy identified short-cct diode as listed below.
0402-001194 Diode is a Gen-purpose 200V 2A diode. I used a 1n4007 (1A), so I expect to have to replace it in future. It's "D1S35" located very close to right rear corner of main board, part of 15V and 12V rails. Next time I'll use a 'faster', higher rated diode.
I also had no clock progression. Time could be set but would not advance. Been like that for ages - I thought it was a user clock-setting error. Identified Dead 32.768 khz crystal (XT601).
Hired manual $10 +postage
Non-faulty parts + postage $40
1 diode $1

The diode part number is SHG2D rated at 200 volts 2 amps, The printed circuit board number for this diode is D1S35, Location: back right hand corner of the printed circuit board, I used a BY299 rated at 800 volts 2 amps, Now working, Hope this helps,

I had the DVD portion of the DVD/VCR combo simply stop dead and the dvd tray would not eject. After talking to Samsung, this is what worked.

Hi, Gladrags here again.
The $1 diode blew . I've used a BYX71-600 this time. Using a $20 diode is overkill I know, but that's what was sitting around. The 'front' of the diode package faces the rear of the DVD unit (for those without a ref chart).
