Anyone care to help me with a mystery screen? - Page 2

Here's the pics you requested as well...

Can you post a better pic of what the white and black wires are? Are they just RCA inputs?

Peoples · 01-15-2005, 08:52 PM

i'd get them out of a car your friend was selling

Not sure, i'd just try soldering to the pins, and making your own connectors. Cur the plastic around the pins, and just tin the edges, wouldnt be a hard soldering job.

Peoples · 01-15-2005, 08:53 PM

my camera is ****. But yeah the white and black wires are just RCA.

If you check each pin, and find the one that goes to the black side of that cap thats Labeled 2CS 100 16V that will be your ground and the one next to it should be 12v then all you have to do is attach the other two wires for video

Get the conectors from an old pc look for the ones that got to internal speaker(this one have four pins) and also try to use the pins as well(use you soldering tolls for this).

Also check if the tracks goes to the power area(the one that have a lot of power transistor,condensors and resistors)

Check continuity for the conector to diferent parts of the board.

Heh - unless you have some big quid, you're SOL. They are proprietary connectors from overseas (Taiwan, I think). They're only sold in large quantity (1000 lots, etc). You might be able to get free samples, but the mfr. is in Taiwan and their website isn't in English.

Let me know if you find a source, because I've been looking for them as well...

Thanks guys...one more question though - why would there be two RCA's? Two separate video inputs?

There are two switches that you can kind of see in one of those pics, one says "TURN LR/UD" which obviously turns the signal for up/down or left/right viewing, and the other says "S/D OFF/ON" which I am not sure of...

Two RCA's? The two video lines are for VIDEO and VIDEO GND...to one RCA.

Can't help with the switch labels.

Removing the tape or whatever that is from the bottom of the board before taking a picture of it would have been a BIG help.

From what I can see, the two center pins are connected to the ground plane on the bottom of the board. Those are your ground points for your power and outer conductor for your RCA jack for your video ground. Doesn't matter which of the two center pins goes to each of them because they are both grounded.

For the other two pins, the one furthest from the corner of the board has a thick trace going to a power filter cap on the top of the board. That is your 12V input. That leaves the pin closest to the corner of the board, with the small trace, your video input which you need to connect to the center conductor of the RCA jack.

Here's the best I could do with removing all that old tape off the backside.

Rover_Eli · 01-16-2005, 09:57 AM

Also, is this what you mean by separating the outside and center conductors for the RCA cable? Would I run this straight to the board on those two pins on the right?

jcdillin · 01-16-2005, 10:00 AM

yeah you got it, now the red is going to go to the pin closest to the edge of the board and the gold unshielded is going to go to one of the middle pins.

strohmrs · 01-16-2005, 10:13 AM

Yes. Just wire that up as I indicated on the picture in my previous post. Hope it looks good!
