Accoustic solutions LCD26762HDF

[brainstorm]

Hi,

I have a Accoustic solutions LCD26762HDF which is fitted with a Vestel chassis, the fault is that the picture comes on briefly and then the set goes into standby. I have checked the 24v to the inverter and there is a 3.6v on the same plug and both voltages disapear when the set goes into fault.
The power supply is a 17PW22-4, has anyone had this fault? I,m sure this chassis is fitted in all sorts of brands of set.

Regards

Brian
