Intec PS1 video screen

[bigjer73]

I have an Intec 5" LCD TFT dock that was made for Sony PS1.
It has AV multi-in, Svideo and composite inputs. It runs on 7.5 volts.
Is there a way to convert it to a VGA input.

Any help would be greatly appreciated.

Thanks-Jerry

Not easily, as the RGB pins are wired straight-through, and do not go to the screen. I seem to recall an RGB mod for these, but I can't locate it now.

Tom, the only connections inside the dock for the PS1, are the 7.5v power supply and the AV Multi in. So I have to assume that the AV input has to be connected to the LCD screen circuitry some way or what was the point of this product? I think any mods to this screens circuitry would be the same as a Sony PS1 LCD, but I am not sure.
Any advice or references that you could supply would be greatly appreciated.

Thanks-Jerry

Hmmm... I may just be remembering wrong. I thought that the 5", like the 4" that I had, only used composite video from the PSOne.

Open it up to see what wires go from the AV multi-in to the screens circuitry. If it has more than 2 or 3 wires, you can do the VGA mod. Just a note, the VGA mod will not let it run on any VGA card, you have to change the output from the PC as well.
