I have found one dying cap CP78 on the power supply board, but can't seem to make much headway. The second question is, does this model work in normal operation on the PC 640*480 VGA mode or did Apple not allow this in this model. The Apple data sheet isn't particularly explicit. Thanks Andrew this unit supports other resolutions than 640x480 but you need a computer which supports multiple frequencies monitors on (very) old macs, this display is black. does it turn really off or does only the led comes yellow after 2 secs ? if it is, it's probably not a power supply fault, but a logic (video fault) as the monitor detects the video and comes green only if it has video it can display. dont know also which sony model it is.. -- Jean-Yves. |

This monitor uses a sony CRT, but was designed by apple. I don't think there's any way to get a schematic of it. Apple only supplies enough information for board swapping. Andy Cuffe |

Were you thinking of the Apple 21inch color display M3502(different model) in your answer Yves ? My studio monitor is a 1999 manufacture for connection to a G4 (Translucent plastic and gray). (I have one of the older model as well, just can't be bothered to fix it yet!) regards Andrew the both monitors support 640x480 and both have a failure mode with a yellow led when they dont detect video. I saw lots of them die this way... It can be fixed (I saw tv servcie mens fixing them..) but I dont know how.. by the way dont trust the man selling you the service manual, I can send it to you if you want, there is nothing on it only take apart methods. there is NO schematic as apple dont give them. apple relies on modules exchanges and dont publish any schematic of any of their models. -- Jean-Yves. |
