The premise is that I needed to have MORE than 2 screens for the in-car DVD player we take on road trips.
I used an INTEC 5.6" screen for Playstation 2 (chubby) bought off Craigslist for $15. Not having the requisite PS2 for it to clip on (I don't do games, sorry) I decided it needed a new shell.
I'd like to have had a better screen to use; this one has atrocious contrast and poor color, but hey, this one is going in front of the 2-year-old and it was CHEAP.
My DVD player is an RCA dual-screen purchased from Tiger Direct. It has served us well on road trips before, but new additions to the family require more viewable screens. I could have bought a second DVD/LCD combo, but that would mean I would have to climb back to start DVD's twice as often. And I am lazy.
Step 1: Free the LCD
Step 2: Preparing to Add an Output Jack to Your Existing Player
First, I de-soldered the camcorder jack from my dead camcorder. This jack allows composite video and L/R audio through the associated 'camcorder' cable. Since the add-on screen had composite and L/R RCA jacks, this was the natural choice. Also, desoldering braid is a beautiful thing, if you have never used it ;)
Next I plugged the camcorder cable into its own jack and used the continuity function on my multimeter to find which pins corresponded to the rings on the plug.
Lastly, I opened up the case for the DVD player and I plugged the AV jacks into the Master player to determine which contacts on the board corresponded to RCA pins.
Hopefully I have labeled all the pinouts correctly, but when in doubt...check continuity!
Step 3: Placing the Jack in the DVD Player
There was plenty of room in the back of the main DVD unit. I just drilled a hole and glued in the jack.
I used quick-set epoxy on the 'shoulders' of the jack (where the faces would solidly meet) and used hot-glue to strengthen the connector once the epoxy was set.
I think a little epoxy made it into the plug, because it is exceptionally snug now finished. It works, though.
Step 4: Making the New Case
I used a $1 pencil box from a Dollar Store.
What was nice was that it was nearly clear, so to cut out all the holes, I just held the components behind and traced with a Sharpie.
I used a Dremel to cut all the slots and openings, and a couple of files here and there to smooth out lines.
The REAL last step is to cut slots to run strips of velcro through so I can attach it to a car seat.
Hope you liked it.
