I manually went in and disabled my display, now it powers up, but no display… (don't ask me why i did that) i was trying to troubleshoot a display problem and following a youtuber i disabled the display… Can i hook up a hdmi and use my tv or another computer screen to go in and enable the display?
Lenovo yoga 700, no display?

See if you can bring up the computer in Safe Mode and repair it from there.
If not, if it is a recent version of Windows, on a different computer, see if you can download and create an installation DVD or USB and boot from that device and see if it offer a repair option.
If that fails, seek professional help or go for a complete reinstallation of the operating system.
Take this as a warning. Never do anything to your computer unless you understand exactly what you are doing and what the consequences will be.
