I have a 7100/66 that is part number 820-0555-A, maybe it is close enough... what part are you missing?

Do you have speakers attached ? The Cube does not have an internal speaker, so you would not hear a chime if you do not have any audio devices attached.

Google AI says this: Single vs. Dual MOSFET Exception. Occasionally, a 6-pin package houses a single high-current MOSFET where four pins are tied together on the PCB to act as the Drain, one pin is the Source, and one pin is the Gate.

It looks like component Q26 is marked as 433B4. Someone will have to identify or decode that marking. I hope that helps you. I have an mSATA to IDE mini adapter inside a 3D printed tray mounted in my PowerBook G4.

I will pull the top off my A1046 tonight and try to get a photo of the label on top of the component for you.

Is this the 15" A1046 (Powerbook5,2), A1095 (PowerBook5,4), or A1138 (Powerbook5,8 DLSD)?

I am by no means an expert on the VRM itself. There is another thread here. External links to A Super VRM currently not available. Some rebuild instructions here on MacRumors. I only have one working Cube, with a 1.2GHz G4 and the stock VRM seems to be fine. I have 5 other shells I collected...

Welcome to the forums! Lots of Cube threads here: Adding Sata SSD to Cube iMac slot load drive in Cube I think the most common failure is the VRM?

Welcome to the forums! I definitely think you can make one good one from the two of them combined. Just go slow with the disassembly and follow the great guides on iFixIt.com, here is the specific one for a 5300 screen.

You can create a wired connection for local devices by using a router in bridge mode. Basically the router connects to your building's wifi, and provides 1-4 wired connections for your local devices. You can get routers at the local thrift stores for cheap. If the particular model you have...

I don't know about the CRT model, but all the LCD models work fine at 24v. I haven't seen actual 28v come out of any of my G4 tower ADC connectors.

I think there were two motherboard versions: Tsunami and Kansas? Is there a dimm in the socket between the ram slots (bank of 4 ram, offset socket, bank of 8 ram)? If there is a dimm there, try removing that. Also, try removing/cleaning/reseating the G3 card. You can try removing extra ram...

Welcome to the forums! Hopefully you don't have to leave things behind. When you sell/donate/rehome your cherished devices to another loving collector, they will continue on with their usefulness. If you are trying to sell/rehome, it helps to list your location (or general area), so that...

Could it be a failing PSU that takes a while to get warm and fail? Just measuring the voltage output without load does not always signify a working PSU. I know it is grasping at straws, but you have tried everything under the sun.

Just remind us in August 2027 about G5tember so we have a little time to prepare next year!
