Someone asked me to fix the power jack on a vTech VM333 wireless baby monitor. Not finding a howto video and finding the search indices have been spammed with useless links to sites that have been hacked just to get my e-mail address it was necessary to use a bit of brute force. Here's what was learned...
This device case has three layers: the front, a middle, and the back. The circuit board will remain with the middle layer after opening. Beware: opening the device certainly voids the warranty and will likely result in some cosmetic damage to the exterior. When you get to the front cover, don't pull it away from the middle layer right away. More on that below.
Tools needed: two spudgers or two very thin jeweler screwdrivers and a #1 Phillips screwdriver.
- Remove the battery door
- Remove the battery.
- Remove the two small Phillips screws in the battery bay.
- Using a two small flat-blade screwdrivers, or one and a very thick thumbnail, separate the back from then middle layer slightly with one tool, then force the other tool into the locations 1, 2, 3, 4, and 5 in the illustration. This will release the back cover.
- On the circuit board are two small Phillips screws. Remove these to release that end of the front cover.
- As done previously, separate the front cover from the middle layer slightly, then force the other tool into points 6, 7, 8, 9, and 10. Note that points 8 and 9 are significantly deeper to reach than the others but they are manageable with decent lighting.
- Do not pull the front cover away from the middle layer immediately. First, separate it slightly and remove the speaker retainer clip. The speaker wires are soldered to the circuit board which remains attached to the middle layer.
- Pull the speaker away from the front cover if it is stuck. Careful when prying around the edge; the speaker has an easily damaged diaphragm on its surface.
- Remove the front cover.
Reassembly is the reverse order. Position the speaker carefully and replace the retaining clip before snapping the front cover into its final position.
