From service mode some settings can be changed and the ink absorber counter and some registered data can be resat or deleted. There is no reset procedure that can repair a defective printer.
A service manual covering models Canon Pixma iP4000 and iP5000 is found here. Before downloading see this instruction.
You can read about service mode operations from page 1-15 and on in the service manual.

I've found some Drucker youtube videos on removing the power supply and checking the pin voltage (with the power supply plugged in). The power supply/adapter was easy to remove, but the ip5000 one has 9 pins and the videos are all showing test voltages for 5 and 6 pin units. Has anyone seen a pin out diagram for the 9 pin power supply?
The videos are in German, but some of the comments are in English with the author replying in English...so I could see what can be learned by checking the two standby voltages and it's worth checking.

Could you please post links to these Youtube videos from drucker(-channel.de?)?
With 9 pins there most likely are four output voltages from the iP5000 power supply. I assume there is one control pin, 4 ground pins and 4 voltage out pins. I searched for info about that power supply but found none. So I think it trying to test the standby and possibly also working voltages makes no sense if you don't know what the voltages should be and the pin-out of the output connector.
But according to the druckerchannel.de Canon forum these power supplies fail very rarely. Instead a defective print head and/or defective logic board prevents the power supply from turning on.
If you remove the print head and the printer will now turn on, but of course with an error message about a missing print head, you know the power supply is OK.
A new print head might then bring the printer back to life, but there is a risk that the logic board has been damaged by the defective print head, With a damaged logic board the printer will not work properly or not at all and the damaged logic board might damage the new print head, making installing a new print head a gamble.
I have already written something similar to this, see this, this and this post.

Here are the Drucker videos I mentioned, I found them searching for "ip5000 power supply" but they aren't about the ip5000. I don't speak German so I could only make out a few words, but the diagrams helped towards understanding.

Reading the comments (and the replies) I gathered that if the standby voltages are correct, the odds are high that the regular voltages will be correct and the psu is good. That would then point towards the logic board as the culprit.

That sounds reasonable to me. But the pins in the power out connector are very small and are closely spaced, and there will most likely be a ground pin next to a voltage out pin, so I think there is a high risk of creating a short circuit when testing voltages using normal test probes. What damage will a such short circuit do? To avoid such risk I made some adapter cables to test the MP610 power supply, but sadly these cables don't fit the smaller connector on an iP4000 power supply. I don't know the iP5000 power connector and the spacing of the pins. Be very careful if you want to test the stand by voltages using normal test probes.
To turn on, meaning change from stand by to operating, the power supply needs a control signal from the logic board. A missing control signal could be caused by a defective logic board but could also be caused by a defective print head that fails a test made by the logic board.
If the printer can turn on with the print head removed it means the power supply is OK and the logic board might be OK but the logic board might also be damaged by a defective print head and still function partly so the printer will turn on without any error messages. A logic board that has been damaged in this way can ruin a new print head.
If the printer can turn on without print head a new print head might save the printer, but the new print head could also be ruined. It is a gamble. In service manuals for newer Canon printers it is recommended that both print head and logic board is replaced in case of a print head failure.
I think a true new and unused print head is nowhere to be found. Beware of print heads from the far East. They are probably used and defective heads that have been cleaned to look like new and are packaged in counterfeit foil bags and cardboard boxes.
Apart from finding a new print head I think the problem is the condition of the logic board and sadly I know no way to test it.

@jbclem By re-reading the thread I noticed the ip5000 will not turn on without print head, which means power the supply and/or the logic board is defective. I also noticed that you have one more iP5000. If that one can turn on without print head you might try installing the print head from the other iP5000 that printer. You might be lucky that the print head is OK and will work now. Swapping print heads between printers for troubleshooting is normally not recommended, but in this case I think you have nothing to lose.
Another test could be swapping power supplies between the printers and see if any of them can turn on without print head. That way you might find a good power supply and logic board combination. Trying to install one of the print heads would then be a gamble but you might be lucky. If not I suggest to give up on the two iP5000 printers.

I'm trying to find an adapter to use in checking out the ip5000 power supply. But that's not easy, and I don't know the correct name for this kind of adapter. It looks like the ground wires are #2, #4, #6, etc... with #1 being on the left(but which is the up or down side?) side of the plug. Even though it's a 9 pin plug, only 1-6 and 8 are used, 7 & 9 are blank(no wires). So I'm assuming #1 is the Red wire and the first one of the 1-6 group.
I'm also going to pull out my other ip5000 and pop out the power adapter and give that a try.

The ground pins are likely connected internally, I guess you have tested this?. As a control input is needed it is likely the power supply has three output voltages. Maybe these voltages are stamped or embossed on the bottom of the power supply?
I think the control input is a yellow wire, and black and maybe white is used for ground(s) and blue and red and ? are used for voltages out. But this is guessing based on measurement on other power supplies. So what are the wire colours on your power connector?
I don't know what the power connector is called or where to buy one. But old computer cooling fan cables, mouse cables or analog sound cables for old optical drives might be a source of connectors from which wires with suitable contacts can be salvaged. These connectors are smaller than these used here and fit an iP4000 power supply. I think they might also be suitable for an iP5000 Power supply.
Here are some of these cables and connectors, notice two different size connectors on the analog audio cable, click to enlarge:
Here is a close-up of the small of the analog audio connectors, click to enlarge:
Here the wires are removed from the connector, and one has been insulated, click to enlarge:
With the contacts insulated there is no risk of short circuits when the contacts are attached to neighbouring pins on the power supply, click to enlarge:
Good luck with making the test cables. When extending the small cables to connect to the DMM remember to insulate the soldering joints using for instance heat shrinkable tubing.
