Give more info what repair kit you was use (power supply)?
Do you have back light?
If not check 24v to inverter board.

Check 3.3 or 5v on pin 2 or 3 not remember
they need to switch on inverter board
do you have back light for 1-2 second? then could be one of transformers faulty.
if not then check small smd fuse on inverter board

Good luck
