Replacing CRT with LCD

Dear I know it is outdated but I have an e Mac G4 1.25 GHz machine which I love very much and am going to replace CRT with an LCD but I want to use its own power supply to run everything and have omitted the high tension components and now it switches ON but needs to connect the round IVAD board so I need the circuit diagrams of analog board and details of Vga Connector Pin 4&10 with yellow wires and said to be I2C line.

I will be very thankful if you can provide me on rinclairelectronics@Gmail.Com

Thanks anyway but please reply whatever.

Could you please tell me about conversion CRT to LCD, I have one eMac G4 700, and want to move CRT to LCD :(


What you want to know and technically what can you do in electronics, I mean at what level you can work and understand.


Oh sorry for missing this message. I can solder and have suitable instruments for that :)

I couldn’t find a diagram of the board, but I did manage to dig up some info that could help. You will have to view it via The Wayback Machine as the original site is long gone.
