Audiovox 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?"
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!
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...
Pull the Board Out
There it is, after pulling a whole lot of cables. Remove the lid switch too, pointed to in the picture.
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.
There's the Problem!
This power jack is broken in half! The second picture shows a broken solder joint.
Replace the Jack
Shown above is the replacement jack. Check the footprint before you replace it!
Put It Back Together
Make sure you connect all the ribbon cables correctly.
You're Done!
Give yourself a pat on the back and enjoy your newly fixed DVD player!
