Liyu SC631 dont start.

[Manuel V]

I have a liyu cutting plotter and it won't turn on.
the display is flashing and at the same time the blade goes up and down. But the car does not move.

I appreciate any help you can give me.

Since nobody can give me any kind of help. I kept researching on this team.
The problem is in the source.
It costs 129 dlls in China. which is a very high price for this cutter model.
Checking the source, it appears that the Mosfet IC is bad (open). now I will try to locate it. is the FS5N60

Hey.

I mean no offence by any of this so please don’t take it the wrong way.

The issue is your on a dye sublimation printing forum which specialises on dye sub the other forums are more for a chat with other users in the same field.

No one here is really specialised in diagnostic of cheap Chinese cutting plotters.
Most of the time diagnosing a fault like this would require the machine to be physically looked at and diagnosed rather than a 2 paragraph statement.

As an ex electronics engineer I would advise you to take it to authorised repair store but as it’s so cheap you may as well tinker with it maybe replace a board for a few £££ and then buy a replacement if that fails.

Look on eBay for spare parts you may be surprised.
