I have an hitachi 32in 32ld8d20u, it has perfect sound but no picture, when you start the tv up the screen will light up then go dark, i have shined a torch into screen but not even any faint picture.

Was told that it would need a new inverter board which i have changed but still the same problem.

Anyone got any ideas as i would really like to get this fixed asap.

hi
check the supply to inverter panel should be 24v,
possible the panel faulty,one of the transformer sometimes
goes o/c
sparky

mulja:
Hi
check on inverter board on pin 2,3 must be 3.3v and 2.5v
pin11 to 14 24v
if voltage present then 2 posible faults inverter board faulty
or on of bulbs in the screen shorting
but you shore what no back light becouse very common fault is on lcd controler board
no picture with back light present.

shaunp2008:
apparently there is 24v showing have changed inverter board and still no picture grr, not sure what else it could be, there is no slave inverter board in this tv either

sparky:
hi
it points to the screen may be faulty
