Introduction: HACKED!: Portable DVD Player

Picture of HACKED!: Portable DVD Player

In this small project I will show you how I "hacked" an old portable DVD player. It did not have a video input which makes it pretty much useless, because who watches DVDs nowadays? I took a look inside the player and found a way to input my video signal anyway. Feel free to use my method to "hack" your own portable DVD player.

Step 1: Watch the Video!

The video will show you how I did this small "hack". But I will give you a small explanation what you should do when you open your own player.

Step 2: Identify the Boards!

If you do not have the same player it will have other boards and other components. it is always a good idea to identify those boards and know what they do in the circuit. This way it is easier to assume where you can input a signal or tap a signal. When you know which ICs do the main jobs it is time to search for the datasheets or reverse engineer those.

Step 3: Search for the Datasheets!

I found the datasheets for the main processing IC and the LCD driver board IC pretty easily. After I looked through those it was a easy job to input my own video signal.

Step 4: Success!

If you did all the steps correctly then you should be able to hack your own portable DVD player....hopefully.

Hi! I1m working on this media player that has not dvd drive, just a memory card slot and two 3,5mm jack AV input, but it cant recognise any signal. Then I tried that you did, i took apart and found the IR3Y29B processor, and the wire for it, but the wire cant recognise any signal too. Could soeone help me out what could be the problem? Thanks! (sorry for my bad english)

Try grounding pin 39 0f the IR3Y29B

Also, connect pin 3 to the Yellow RCA connector.

i have portable dvd player it use hwcat d3031 and hwcat csc1004d anyone has the datasheet or pinout?

Thanks for sharing. I am trying to do the same thing with a portable DVD player (FL-125) and the main processing chip (SVP7188P) seems to be integrated with LCD driver functionality. I can only find the data sheet with feature descriptions that clearly indicated that there is video input but I could not find any literature on the schematic. Any idea on how to identify the pins or the schematic would be much appreciated.

I'm working on a portable dvd player myself, however, I'm stuck. It also only has the a/v out, but it doesn't have a seperate driver board. It looks like the connections go straight from the mainchip right into the lcd. I found a pdf file with the pinouts of the mainchip but I'm having trouble figuring out which pin to use to hook up to my raspberrypi b+. I'll post some pictures if you or someone else could help me out. Thanks!
The mainchip is a "Mediatek MT1389KQE"

Bryanmatthew7,

Did you ever find a way to get your own video signal into that Mediatek MT1389KQE chip? I am attempting a similar project.

Sorry, but you cannot adapt this particular model. I have an old portable dvd player with the same chip, and it simply doesn't have av inputs. (It has component inputs, but I can't find the pinouts) However, pins 44-47 should be a USB port, and you should be able to play DivX files off of a usb drive if you connect it to those pins.

I'm one of the unlcky guys with this model, however i found this 22 connection wich is a VCOM signal going to the TFT screen.

Could it be the "PIN" you are looking for?

That's a neat upgrade to an old dvd player! Thanks for sharing!
