Hey all. Recently I purchased an Apple Color Monitor (model A2M6020), unfortunately after receiving it I noticed that the screen was acting funky. After talking to a friend I learned that the capacitors need to be replaced. Was wondering if anybody knew offhand what type of capacitors it uses and how many.

Console 5 stocks some monitor kits (like the IIgs monitor and Commodore 1702), but doesn't stock a kit for this monitor. And as far as I know, no schematic exists for this monitor either. I recapped my Color Monitor IIc (which I think is the same as the 6020) a while back and had sent him the list of caps, but he never did anything with it. Here is the list of caps I found in mine. The list should be accurate, but double check everything against yours. Apple really skimped on quality caps in this monitor. Some no name chineese cap in most cases. Samyoung may have been in partnership with United Chemi-Con at the time, as they used a similar logo. So those might be decent quality. Or they were ripping them off by using their logo, not sure. One of the main filter caps looked like the top was bulging. I think that was C506? But it may have been manufactured that way, hard to say.
C514 I guessed is a low leakage cap. In the 80's special caps usually had bright yellow or orange sleeves. They could denote they were "low leakage" or possibly low ESR. Since that cap was yellow, I treated it as such by using a Nichicon KL series (ultra low leakage). But I don't know for sure. Can't say it seemed to hurt that I used that particular cap. For the rest I just used good 105c Nichicon and Panasonic caps.
