Screen and touch bar stopped working after battery replacement

I followed this battery replacement guide: MacBook Pro 15" Touch Bar 2017 Battery Replacement and apparently everything went fine. However, my screen and touch bar are not working anymore. The caps lock green light works, and I can hear the sound when power cord is plugged, but both screen and touch bar remain black.

I've tried to reset SMC and PRAM but nothing changed.

What do you see on an external display? Do you see your desktop?

@danj I tried connecting my Thunderbolt Display, but it shown nothing, like it wasn’t connected.

@bisewski Did you remove the battery connection before you went through and removed any other connections?

@ellispctech I followed the steps of the guide. Disconnected battery from logic board before disconnecting anything else.

Ok, and was the battery a brand new Apple branded battery, or was it an off brand?
