Digital Caliper

LOL when was the last time you saw a schematic for a cheap Chinese anything?

Check the obvious like dirty connectors or cracked joints, otherwise buy a new one.

Hé James, this is sci.electronics.REPAIR, not sci.electronics.buynew ;-}

If the device needs FCC type acceptance and the filer didn't request confidentiality, schematics are often available on 'gullfoss' (unfortunately digital calipers don't radiate much RF ;-) )

That's why I said check the obvious stuff, if the problem is not obvious, then you don't stand a chance. These things are truly not meant to be repaired, doesn't mean you won't succeed, but you won't find schematics or replacement parts.
