Hi Shaun,

You don't mention part number for the PSU. Is it a long board that plugs into the CCFL sockets at the side? Attached service bulletin is all I have for
this Model.          Bruce

Hi Shaun,

I note it uses a FAN7530 IC - I think these have been troublesome. Schematic attached.                            Bruce with a C

Had same fault on a similar Sammysung, 'in my case' it was the chip as downunder said in the previous post.
