Introduction: Magnavox VBP3900 Repair/Teardown
The DVD player, ready for disassembly. Please excuse the very messy bench. :P
This DVD player, made 12 years ago, is the subject of my first 'ible. I have been having power jack troubles for some time, so I decided "why not fix it?"
Step 1: Crack Her Open!
There are four screws on the bottom, SOMEHOW not hidden by rubber feet. You will not, however, need four screwdrivers. Make sure to keep these screws!
Step 2: More Tearing Down
Lookit that! If you have a chance, plug it in and insert a CD. Cool, right? I'll link a video. Now we need to remove the board with all the cables coming out of it...
Step 3: Pull the Board Out
There it is, after pulling a whole lot of cables. Remove the lid switch too, pointed to in the picture.
Step 4: What's on the Board?
...Not a whole lot! The white arrow points to an L7808CV linear regulator, and at the very back of the board is what I believe to be a MOSFET.
Step 5: There's the Problem!
This power jack is broken in half! The second picture shows a broken solder joint.
Step 6: Replace the Jack
Shown above is the replacement jack. Check the footprint before you replace it!
Step 7: Put It Back Together
Make sure you connect all the ribbon cables correctly.
Step 8: You're Done!
Give yourself a pat on the back and enjoy your newly fixed DVD player!
