lg lcd tv rz32lz55

[stu]

this lg lcd tv is driving me mad..soon as you power it up it runs with a great picture for approx 2 seconds then the screen goes blank..i have changed the inverter board but the fault still remains..cant find anything obvious so anyone got any ideas or circuit diagrams would be great.
i cant hear any sound either but it does not stay on long enough to find out! :wacko:
i am sure it has chassis number ml041a

many thanks

You try start up inverter board just take 24v from tv power suplly
and connect 5v from external power supply just touch the pin if inverter
back light flash for 1,2 sec and goes off then fault in inverter

Could be lamps in screen
