Hello,
You can get complete power supply as one part from Sony. You can't repair it on component level because components are not available.

Hello
Its poser SMPS bard inside is not working properly. This board supplie low tension voltages to the other circuit boards of the device. It is a Switch Mode Power Supply [SMPS]. Normally repairing is not effective to this board. Replace the board as card basis is good. you can bought it from most of the elelctronic spare part shops at your town. There is a number printed on the printed circuit board and it is its identification. Note that number, and buy the same type. OK.

Has anyone ever solved the 'locked' tray problem on a Sony DVP NC85H?


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.

My kid broke the blue optical lens in Sony DVP-FX930 Portable DVD Player. Can i replace the optical lens part from any other dvd drives or is it unique to sony. Please advice.


Portable DVD players are made up of the dvd mechnism, control motherboard and LCD panel. You can buy a defective Sony unit on ebay for parts and replace the dvd mechanism assembly.

Most defective portable dvd players are defective on the control motherboard, just read the defects disclosed on ebay items to decide which one to buy to fix yours.

Disc is stuck on playhead, won't come out on carousel.


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.

Unfortunately if the door is latched but with power then the loading motor section is struck or failed. If there is no power at all the power supply unit has failed. you will need to check on the SMPS unit . Check my tips column for SMPS maintenance.

Cannot Close Sony DVP-NC665P 5 disk tray


There is a possiblity that he may have shifted the unit while discs were in it causing the discs to slip off the tray and into the unit. You have to open the unit to check if there are loose discs.
