My TECNO kb7 is total dead after I replaced new LCD display, till now when you plug in charger the charging indicator light shows white but nothing on both the old LCD and new LCD display. Please I need help my seniors.

Does pc detects the phone?
Did you take note of the phone’s build no? *identify using https://www.hovatek.com/forum/thread-16005.html

PC detected USB error , because of that I was not able to identify the build number.

if this is the case and you are sure that the device was able to boot before replacing both those items, then you must check other hardware parts
