To the floor it crashed ...

[SlowCoder]

I have a Polaroid DVD player, model PDV-0821T. It took a trip to the floor, breaking the power receptacle.

 

I would like to know what I need to know to see if the display could be used for an Atari retrofit? Perhaps much in the same way as Ben Heck's PS1 mod? I have another DVD player, so it's not important to resurrect this one as a player also.

[dooglehead]

does it have a composite video input?

does it have a composite video input?

Interesting question. There is composite input to the player itself, but not directly to the display.

 

AND ... the player uses 9.5v DC, closely compatible with Atari ... Hummm!

If you could get a model number for the actual LCD, you could see what its scan range is and see if the DVD player was doing any conversion to make the picture viewable on the LCD. Then it would just be a matter of either wiring it up or building (or removing) the converter circuit.

 

As for the power, make sure that the ampereage is correct as underamping a circuit can damage it.

I took apart the DVD player, and have removed the LCD screen from the rest of the chassis. It has a simple swivel mechanism, so I think I'll just be able to drill a simple hole in the top of my test Atari and mount it in there without much difficulty, making for a pretty cool portable console!

 

Cracking open the LCD compartment, found a couple of stickers on the back of the actual LCD component, but I can't tell which might be the model.

 

There are 3 bundles of wires on the LCD that I disconnected from mainboard. Here are the markings for the pins on each bundle:

 

Bundle 1 (Assuming this is Audio)

1: SC

2: GND

3: TFT_CVBS

4: GND

5: GND

6: GND

7: ROUT-

8: ROUT+

9: LOUT-

10: LOUT+

 

Bundle 2

1: INT/EXT

2: PAL/NTSC

3: -13V

4: 3V3

5: 5V

6: 7V5

7: 17V

8: GND

9: GND

10: GND

 

Bundle 3:

1: 9V

2: 9V

3: GND

4: ON/OFF

5: GND

6: GND

 

I realize I'll probably need to convert my Atari to Composite A/V.

 

The power adapter for the DVD is 9.5V, 3A. Should that be enough to power both the Atari and the LCD?

 

Techie guys, how might I wire this to my Atari?

Tell me if this helps.

I googled TFT_CVBS for kicks, since TFT is a type of screen.

Pin 7-10 on the first bundle does look like audio. The first few pins on bundle one though look like they may be video along with some on the second bundle. The 3rd one looks like it is power. If the LCD doesn't take more than an amp, I would think you could use the 9v, 3A PS to power both. I would definitely check the power before hooking everything up first to make sure you are getting the power you are looking for. Underamping a circuit can really do damage to it.

Interesting question. There is composite input to the player itself, but not directly to the display.

Are you certain that's not output?

Yes,I'm sure. The system is capable of both input an output using the same composite port. There is an in/out switch.

 

I had examined just attempting to mount the DVD mainboard inside the Atari, and on the back of the LCD. This would definitely make this project easier, but there's not enough room inside the atari, and mounting on the back of the LCD makes it too bulky and it wouldn't tilt the way I'd like.
