    Hi all someone pointed out that it looks like there is a cap on the v-sync from my diagram. There isnt. The cap is on the 5V line and not the V-sync. I will update the diagram and make it a little bigger.

    Hello,

    Kinda new here. For some reason i can't see the diagram for the 3.3 volt mod. I just bought on Datalux LMV10R on ebay and would like to mod it. Could you please email me the picture of the circuit.
    Thanks.

All you need is a 74HCT04 Hex inverter and a 0.1uf cap. You wire it up so the H and V sync lines each go into one inverter then that output goes through another inverter and that output you hook to the screen. Here is a little diagram. And its only two parts!

    I am selling one that I already modified and tested so if you are interested in that go check the For Sale forum.

    I updated the diagram a little. Its in my post about 10 down form here.

    Sorry I've been away for a while. I got real busy at work.
    Not sure why the pic I posted is not there anymore but I will put it up again. I also took some pictures of the inside of the screen before I sold it and will see if I can get those up here somehow.

    That helps so much!!! YOU ARE THE MAN!!!! I can pick up the parts on the way home from work and get started on upgrading the monitor.

    I'm looking forward to getting an ITX computer, probably a Epia-M 9000 and a 40 GB HD. Just hope a 60 Watt DC-DC converter can handle it.

    Works like a charm! I had to order 10 of one of the parts, so I have 9 "sets" of the parts needed, if you want, I will mail the IC and the capacitor out for $4 shipped (cheaper than shipping through digikey, and I only had one monitor to repair).

    I cut the yellow (vsync) and white (hsync) wire going to the connector on the VGA to TFT converter board. The IC was spliced in between the wires, I bent all the pins that needed to be connected to each other. The grounds were all combined from the tantalum capacitor that ran underneath it. A lead was spliced, and that ground was connected to the same area on a screw (you can't miss it). I hotglued the whole thing to the wire bundle

    For 5v, I tapped "C8", the center pin on the cable running to the inverter. It's a red wire on my LMV10R. That new tapped wire now has a 3pin male/female connector on it on each end so I can remove the backplate just like normal (I used some fan adapter cable I cut up).

    Thank you Trottingwolf (and your EE friend)!
