how do i add RCA inputs to my portable dvd player?

hi

After moving i unearthed my old, but very big screened, portable dvd player. It used a Li-Po battery which is lost and has been flat for 4-6 years, so its unlikely to work anymore, and even so, i no longer need it. What i do now need is an LCD reverse parking monitor. I have everything but an LCD with RCA inputs, so i figure, why not repurpose my DVD player.

I need to know,  how would i go about locating the correct area in the circuit to connect the RCA input?
I know how to follow tracks, im just not sure what it is im looking for, My first thought was, follow the RCA outputs, and hope that at some point it leads to where the DVD player is producing the RCA that goes both to the output jack, and also to another processor/ encoder/ decoder which then feeds the data stream to the LCD, and all i need to do is sever the original RCA track and use my own, however before i do anything, i want a second opinion, as well as also finding out if my logic is sound. If infact the datastream from the dvd reader is being turned into a decoded datastream for the LCD in the same place that also creates the RCA output, then this wont work, as there is nowhere to put the inputs.

In this case, how would i go about getting my video output to display on the LCD? how would i go about locating a decoder and conecting it up and ect,  just video anyway, for the time being i dont need audio, also the audio track is easy enough to manually hijack anyway.

This is a situation where i would rather spend an excessive amount of effort in getting it to work rather than buying a display.

Thanks

Its probably not possible. The thing to do is identify the chip set used by the device, get the datasheets for the parts (which, being Chinese are usually VERY hard to get, let alone read) and see if there are analogue inputs.

I actually doubt it. The signal path will be purely digital to the LCD

In that case how would i go about operating my analogue signals on the lcd?
Basically, you can't, the LCD is a digital device. Again, only detailed study of the chip sets will help. Its CONCEIVABLE that the display is an analogue input, but very very unlikely. Why convert from digital from the DVD, to analogue to digital for the LCD ? They wouldn't do it.

Thats what i meant, how do i convert analogue into digital for the LCD? This being without anything from the dvd player motherboard, just the LCD.

what would i need?
You need exotic silicon, which isn't easy to find - I can't help much further, because the silicon is only available in complex packages like BGA., assuming you can even get it.

Basically you're looking for the kind of stuff you get in a graphics card like the Nvidia ones, which accept S video in.
