I was looking through the kernal logs of my S9 and one chain picks up 63 asics, but the two others pick up 0. Does that mean they are just burnt out or is there an easy fix?
Did you fix a fix?

Specially considering you don't need to flash it into the controller's nand, just boot it from the sd card by moving a jumper. Don't like it? Take out the card and move the jumper back. Nothing happened.
This point has been discussed a few times before, to me , that is a lot of work when compared to flashing a firmware from bitmain in 10 seconds using only a web browser, now this "a lot of work" is subjective indeed, and depends on a lot of factors, the most important part is not being able to physically access your miner, I am still using bitmain firmware simply because
1-it does what it suppose to.
2-requires no effort.
3-could be flashed over the internet with ease.
So until I can flash braiins' with the same efforts ,I am going to sadly stick with Bitmain's version.
Lower speeds (in mhz), or increase voltage. Lowering the speed is safer, you should only try messing with voltages under 9v, else lower those mhz.
it depends really, i had some hash board that needed a very low frequency to run stable, the only way to have them run at a moderate frequency was increasing the voltage, and giving the fact that those will die soon anyway, plus I needed to ROI asap i focused more on increasing the voltage until there was no room then I started to lower the frequency, but everyone and every board is different.
You do make sense from a technical stand point, i remember using a modified firmware for old school D3 and i was able to bring some dead boards back to life using super high voltage,
However to my personal experience, the chances of "resurrecting" dead S9 boards are pretty low to the point that they don't worth the time flashing BraiinsOS.
This indeed has no scientific back up and simply based on my personal experience and some other miners, having said that trying out BraiinsOS does not seem like a bad plan at all.

As for resurrecting chips there are two things you can do:

No, you can't find any because 2019 firmware just release this year. The reason why I recommend the latest version because the 2019 firmware added multi-option menu in miners configuration where you can set the miner to other option or low power mode. Where you can choose to increase hashrate or to run the miner at a lower frequency and lower voltage.
There are sometimes hashboard works in low frequency and lower voltage so if he had this firmware he can choose what frequency and working voltage works in his two hashboard and you have nothing to lose if you try.
I'm honestly don't recommend newbies to downgrade their miners to lower version which is open port and ssh enabled because there are chances that they can be hacked or become infected with mining virus. Unless if they know how to protect their miners to any of these attacks.

Also with BraiinsOS you can force different speeds and voltages that might resurrect them again. And sometimes its just the silly sensors that are bust. But to use bOS you should avoid Bitmain's 2019 firmware if you don't have physical access or the sd slot in your controller...
Besides i wouldn't trust the way Bitmain lowers speeds. Direct voltage and speed control is better than "minus 1, or minus 2 th", where its probably changing both without giving you enough control. Besides each board requires different settings anyway.
But first thing to try is take out all three boards and test one by one with different data and power cables.

Have you tried to upgrade the firmware to the latest version? The latest version is "Antminer-S9i-xilinx-201907311618-autofreq-user-Update2UBI-NF-sig.tar.gz"
I have not seen any 2019 firmware fixes the problem with hashboards showing 0 asics, the 2019 firmware version/s are only good for those boards that keep crashing , whereby if you set them on lower frequency you might get lucky enough to have them run perfectly.
To my personal experience I had the most luck with this particular firmware "Antminer-S9-all-201711171757-autofreq-user-Update2UBI-NF.tar.gz" , as explained in this topic
There is a small chance that such an issue would be fixed on a firmware level, but chances are the hashboard is dead - fixing it would require some tools and stuff, you will most likely need to replace a faulty chip on that board.

Try flash it first to the latest version then check the miner's configuration and look for working mode and try to check which settings will fix your issue until you choose "lower power mode". If not working do a hard reset and repeat.
You can find the guide from here https://support.bitmain.com/hc/en-us/articles/115003595387-How-to-reset-miner-to-factory-settings-
Do the 1st and 3rd method and ignore the 2nd method.
If nothing works there is a problem on PSU or Hashboard.
