M0401 AppleColor High-Res RGB monitor capacitor list?

[JC8080]

Does anyone have a capacitor list for the M0401 AppleColor High-Resolution RGB monitor? I found a thread with a list for the later M1297 revision, but I was not able to find anything for the M0401.

I am currently going over my monitor and have the PSU and D - Board listed. Please note that this is not 100% verified but is to my best knowledge is accurate. I should be getting the first batch of capacitors in a few days.

Great, this is very helpful, please update if you find any errors in your list. Are you recapping any of the other boards?

Why are you recapping? Preemptively, or to try to fix an issue? Mine works fine but is a bit dimmer than I think it should be, but it's been so many years since I used one of these I really don't remember how bright they should be.

I am glad it was helpful.

I will let you know the progress and if I find and issues.

I was having, what I can describe only as contrast issues that, when the monitor was warm, would fix itself. Figured that was a perfect indication of failing capacitors. I could use my EGR to determine which are good or bad but I figure for the $40 in capacitors, it's a great investment in the monitors future.

Hope all is well!

Here is the main filter cap on the G-board (power supply). As you can see, she's a beauty

That cap looks a bit rough. I heard recently, maybe from Adrian's Digital Basement, that a bulging appearance is normal for those large caps with the plastic bit covering the top of the cap, and it is not necessarily a sign of leakage. That one is bulging quite significantly though, it would definitely concern me. When I have recapped IIsi PSUs I have always replaced the large caps even though people say it is not necessary. I figure as long as I'm in there, and already ordering parts, I may as well do it for peace of mind.

 

[danny.gonzalez.0861@gmai]

Well, everything on the list was indeed accurate. I can share what I bought from Mouser with the exception of the filter cap. Although it was the correct size and value, the lead spacing was off by just enough that I drank an entire beer until I was able to figure that one out but in the end it did indeed work out flawlessly.

I found a few cracked potentiometers so my geometry is off until I care enough to take it apart and/or find the values online.

Also, note that I didn't recap the rear AV board as I didn't see a reason to. Maybe someone can add that last part for the world.

A lot of the caps I removed were Rudycon caps which aren't bad but they were 85c rated and I changed them to 105c high life rating so hopefully the next person to do this will be after I'm dead.

I will post the Mouser list the moment I get home.

Thanks!

Thank you, this is great info!

Hello everyone,

Sorry for the late response with the Mouser list. Got a horrible cold and am still going through it.

In any case, here is the PDF you can use to order the parts from Mouser or cross them to your preferred vendor.

Hope this helps!
