After spraying inspect the fan for any damage and if the fan is damaged proceed to replace the fan. Link to replacement guide Lenovo Yoga 710-14IKB Fan Replacement
Monitor not Working
When turning on the laptop, the back lit keyboard functions correctly, but there is nothing displayed on the screen. When it does work a sudden movement causes glitches and the computer crashes.
Loose Display Cable
