I got my wife a Cyberhome CH-LDV 700B portable 7" DVD player for Christmas. It has a component-out feature that requires a cable it didn't come with. The cable it needs would be an 1/8" 4-lead mini plug on one end, and the three RCA plugs (Red, Blue, and Green) on the other. I can make my own cable if anyone can give me the wiring pin-outs. Anyone want to take a shot at it? Use these lead descriptions when replying:
1/8" mini-plug from the tip down: tip,second ring, third ring,base
Red component: Center, rim
Blue component: Center, rim
Green component: Center, rim
I've got a similar cable (1/8" 4-lead to three RCA) but with Yellow (video), Red and White (Audio) outputs. I've tried all possible YRW to RBG configurations with it, and a few will give me a green or red tinted image on the TV. But none give me true color from the DVD player.
I CAN buy the cable premade right from Cyberhome, but their online store is closed until January. Any help greatly appreciated.

Well, I thought I'd get clever and try to figure out the outputs of that portable DVD player for myself. I have another DVD player with conventional component output. With a BUGS DVD fixed on the root menu in it I used a multimeter to read the voltage of each jack red, green, and blue. There were slight differences, with a positive voltage between the center and the rim of each RCA jack. Then I put that same DVD into the portable player, and used my A/V cable to bring out the contacts of it's component-out jack.
Unfortunately, none of the voltages on the end of that cable matched the voltages I'd gotten from the other DVD player. In fact they were negative, and quite different values. I had assumed the same DVD showing the same menu page would have identical voltage levels at each component no matter which player it was playing on. But either that assumption is not true, or the leads from that little DVD player are quite unusually mapped to it's particular component breakout cable.
So I'm still looking for a clue.
Oh, and Merry Christmas, all!
