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

Hi the repair kit was from ohm supply, 04TA0691. no back light, 24 v between pins 1 and 9, is there any components to check on invertor its a darfon  v070-001 many thanks

hi all ,the inverter is a 4H. V0708.001/E5

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
