Sounds like you have some liquid damage to the logic board at the location where the internal display is connected. You’ll need to open the system up to inspect the connections for damage. Follow this IFIXIT guide to Step 4 " Unibody Mid 2012のロジックボードの交換. Then jump down to Step 15. Does your connector and the solder joints look like this:
If not you’ll need to do some cleaning and you still may need the logic board repaired or replaced (as well as the LVDS cable to the display).

to my knolege the device has never been in contact with liquid
You'll still need to open the system to check things out. Take a few pictures and post them here for us to see iFixitでの質問に画像を追加する方法
Agreed possible liquid damage to the connector.
i will attempt to take pictures tomorow, had the mac appart and completly removed the display assembily to tighten hinges but theres still no life after putting everything back
