Update: I calibrated the board - didnt fix the green tint. G3 would switch on with green tint but after some times would fix itself until I power it down for a some time again I tried looking for a potential place of an issue by using freezing spray and heat gun - no affect on green tint...

yes - lots of artifacts across the whole screen.

My G3 is M5521 slot loading

Where does one buy VRAM chips for G3 these days? I found one on Aliexpress but seller has not sent after a month of wait and I will probably be getting an automatic refund soon. This is what mine has and I need to purchase a few:

Ok the plan is: Open G3 and check which analogue board I installed and compare with the one that I replaced. I definititely know that old board didnt have the tube selection switch (so it was 661-2370). I need to check the one currently in G3 - I think it had a switch. If the currently...

big thanks to Daniel and for the service manual link above - I now know that there are two different analogue boards as well as two different tubes used in my type or g3 :). I am going to check out which one I had and which one I have now to make sure they are paired correctly. Ah looks like I...

I I do have a spare tube - might try that too. Before I removed the analogue and logic boards from donor g3 it had the same issue with green - I thought it was the crt but looks like not since it is doing the same in my main g3

Thank you both I will try all the suggestions. The strange thing is that the issue is not permanent. When it goes back to normal (randomly) the brightness settles too as well as green goes. The very bright green shine of the background is only there when green is visible. I actually tried...

ima Hey everyone, I am trying to analyse what's up with my iMac G3 that quite often has green tint to the all the colours especially after being turned off for a while. When this happens it looks like none of the colours (R, G or B) are missing but they are rather washed out with green. It...

Sorry to hear you are going through what I just went thought. I changed so many components in my Classic (please see my posts above for full list and order of when and what I did). The last changes that seemed to have done it were: 1) installed socket for QP1(CNY17G) and replaced for another...

I can confirm my Mac Classic's 5v rail is stable now! No issues on cool boot after cold nights as well as freezing spray is not affecting voltage now.

Thank you. Yeah I have actually removed all old solder and soldered with new one on all wire connections going into the board: around the speakers and the ones in the middle. The cable connections around the speaker near leaked capacitors were all green and yuk.

Update: well, I don't want to jinx it but I think my problem is fixed. The Classic is stable 5v rail wise from the power on and me blowing on various components on AB board does not seem to affect the stability at all. I am going to monitor how it goes for a few days after long cold nights and...

Yeah maybe - that did cross my mind before too. I might place an order for a few kits for classic so I have it for the future and if I can’t find a solution will recap the recapped jaycar caps. Do you have another classic that you recapped with jaycar caps that works ok and isnt suffering from...
