Where can i find a power supply board for a sony DVP-NC85H multi- disc player

AVI maybe ok. Is there anything error with your converting? I ofen use kigo video converter free to convert video. It's a free ware but works well for me.

Look on the bottom of the unit. There is a hole with the letters ex and op. Shine a light in the hole and you will see a white plastic object with a slot for a slot screwdriver. You can turn this either way but be careful. If you feel resistance and the object does not turn, turn the other direction and the unit will open. Op is open. Ex is exchange.

Another less elegant way is to open the unit's case, take off top cover and get your discs being held inside the unit that way. Be careful.

Of course you could take the unit in for service but may not be worth the cost.

No way but to open the cover the mechanism and remove from the drive of the mechanism.
If the power is present, then check the loading motor drive mechanism , checkthe drive IC for fault.
If not check the power from the SMPS and rectify.
If not the board can be faulty.

Unplug it and plug it wait a few min. plug it back in.
Make sure that it is all plugged in correctly and that the right channel is on :)

Put dvd player in standby mode and press 3,6,9 buttons on dvd remote to turn off progressive scan off. Let me know exact model number of your dvd player if above solution does not work.

laser is bad. usually not economical to fix. laser is around 90% of what you paid for unit. new 5 disc sonys are 129

You should refer to your Product's Operation Manual for help on this. Also, you may goto www.sony.com for more info.

I am getting this error too and I believe it means that somehow the tray that the discs ride on is jammed. I think if you unscrew the three screws on the back and the two on the sides you can pop the top off and see the tray. I bet there is a disc somewhere that didn't fall back into its right spot and it will give you that error... I just opened mine up and sure enough there was a DVD that was in the way... I removed that disc and the error went away. I hope that helps you out as well.

If it works like my sony RDR-GX315 just press the pause button on the player itself and hold for 5 seconds.

not a problem as long you have HDMI jacks on both machine
