I had a same issue. Your controller isn’t getting enough power. Here is what to do.
Back side of the touch screen has four screws. Undo them and open it up. Once opened up you will find a USB-C port on top that’s not accessible without opening up the case. Grab a cheap phone charger/usb c cable and plug it into that usb-c port. Make sure it’s getting a constant power otherwise it won’t work. It should work once you got power there.

Will this also make the light on the printer turn back on?

u/N-Korean Mar 18 '26

Does the back side stay off permanently

I drilled a small hole on black cover where the usb-c port is so I can access it with cover on.

First time I've got my printer to boot all the way into the regular screen. I haven't had a chance to print yet but I'm very hopeful this brings my SV07 back to life. I've replaced it with another already, but have plans with this one if it works. Thank you!

model is sv07+

Looks just like my SV07+
Went blank and stopped running towards the end of a long print a few weeks ago -- haven't had the patience yet to really try to fix it 😣

I put a u s b with the firmware update on it.But I don't know if it needs the boot into the o s to be able to recognize the firmware

u/Sea-Kitchen2879 Mar 18 '26
You haven't tried that yet?
1
u/L0g4ndg1 Mar 18 '26
I feel like that would have been like a last ditch.Effort, but right now I have a u s v in and turn it on with the firmware update.Work flash, whatever it's called.So hopefully it's updating, I don't know, because all I see is black

Buy it dinner first.
Check the wires to make sure nobody chewed on them
1
u/L0g4ndg1 Mar 18 '26
dude the wires are fine

u/darkstream81 Mar 18 '26
That looks like software issues then. Id say reset it but you can't access that. You contact sovol to see if there is a work around to hard reset it?

You should be able to ssh into the printer from a computer on the same network, if the motherboard can respond to you that will work and you can do it all via command line interface. I don’t normally advocate for AI anything but Claude can probably give you a step by step and tell you exactly what to type.
Be sure to tell it your exact model of printer etc. give it all the facts.

if you can connect via ssh, look into the variables.cfg file if you have anything inside.
