how can I fix my hitachi lcd tv 32ld6600B?

If the screen is totally black it is most probably the inverter board gone this is the long board normally to the left or right hand side inside the set usually about £30-£40 on e-bay if your getting a blue screen then it will most likely be the scan board or t-con board as its also called this is more tricky as it is under the main boards in the centre connected to the screen again available from e-bay for around £20-30
