Check transformer on inverter board

fix2003:
Remove the main board screening can
and look where the inverter plug goes into the main board. You will see a number of surface mounted chokes which feed the 12v supply to the inverter. They are usually discoloured and high resistance. Link them out with wire

Hi thank you for the tips here with this Logik lcd tv - I have checked this and it is not the problem however I dont seem to have 24 volts at the inverter socket thats marked 24 volt if thats a clue maybe - the power packed has checked out ok under a lamp load and is supplying a steady 12volts - any further help please

jordan:
On the PCB main board check L-21 and L-168
