I plug in my Samsung DVD V70 Combo player and there is no power up at all? Should I replace the power lead or the small fuse next to where the lead plugs into the circuit board?

You need to Ohm out the fuse, not likely to be the power cord problem, it may have blown fuse or failed switching power supply circuits, or the power supply is detecting shorted circuits so it stays in the shutdown mode. Any sign of bad caps with domed tops?

    So far I cannot locate free service manual for this DVD, you will need it to troubleshoot it down to component level.

Had power outage and now VCR/DVD does not turn back on. lights all work but it doesn't seem to pick up the channel?


Dis-connect the plug from the wall receptical and other leads attached to to the unit. Next press and hold power for too minutes in an attempt to reset the microprocessor, now hook everything back up and power on, if this fails it probably would be cheaper to replace the combo than have it repaired.

My DVD/VHS combo remote control no longer activates the unit. I have replaced the batteries (2 times). What should I do next?


Hi,

Good day. You might need to purchase another remote control so that you can access your dvd / vhs combo. I'm afraid that the remote is already broken due to normal use. You can also try to have a technician to check it for you but i suggest you bring it to a samsung authorized service center. Hope this give you a bit of help. Have a great day.

1.6A250V fuse blows on V3500 power circuit board


Hi,
Your DVD combo use a Switch Mode Power supply.
If you want to give it a bash here is a good guide that explains how they work and how to trouble shoot. http://www.repairfaq.org/sam/smpsfaq.htm
but ...
in 95% of the cases it is a shorted switchmode power transistor and other semiconductors, open fusable resistors, other bad parts. Note: actual cause of failure may be power surge/brownout/lightning strikes, random failure, or primary side electrolytic capacitor(s) with greatly reduced capacity or entirely open - test them before powering up the repaired unit.

I have a DVD VHS combo Model V70 recorder player that simply will not play DVDs, have made it region free in the hopes that it would solve the problem, but still refuses to play DVD dics, any ideaS BEFORE...


You shouldn't set it to region free, instead set it to NTSC if it's and american/canadian DVD, and set it to PAL if it's foreign. If your not sure which it is you'll find it in the bottom left corner of the dvd box.

Replacement mechanisms are shipped with a solder bridge that shorts out the laser to prevent problems with static electricity during shipping and installation. Did you remove that bridge? It should be on the optics assembly itself.
